Putting Off AC Maintenance Will Cost More In The Long Run

Upgrading your HVAC unit can be a significant expense for your family’s budget. For this reason, you may be putting off purchasing a new HVAC system for as long as possible.

Air conditioner repair technician

The old adage ‘If it is not broke, do not fix it’ may apply to many situations. However, in the case of HVAC systems, you should replace your old system before it breaks down.

According to the experts at Energy Star, your air conditioner or heat pump unit should be replaced every 10 years. The reason is technological advances make newer HVAC units more efficient than ever. Efficient units can save homeowners hundreds of dollars in utility costs each year.

By using an older HVAC system to heat and cool your home, you are literally blowing your money out of the window. You may be saving money on the purchase price of a new unit, but each month you are spending more money on utility costs. Older HVAC systems are inefficient and wasteful.

HVAC units are only as good as their efficiency as they perform their functions. Each unit is given an efficiency rating by Energy Star known as SEER. For example, units that were installed prior to 2005 have a SEER rating of less than 10.

To put these numbers into perspective, a SEER-9 system that is upgraded to a SEER-13 system can save your family 38 percent in utility costs per year. That is a significant saving.

In 2005, the Department of Energy mandated that all HVAC units have a SEER number that is no less than 13. This legislation by the federal government is an effort to improve energy efficiency in households throughout the United States.

Understanding SEER
SEER stands for Seasonal Energy Efficiency Rating. This is a metric system that was devised to determine the efficiency of an HVAC unit. If a SEER number is high, then it is determined to have a greater level of efficiency. You can purchase an HVAC unit as high as SEER-23.

A simple formula is used to determine the SEER number of an HVAC unit. The calculation that determines the efficiency of your HVAC unit is the number of BTUs divided by the number watts in the system.

The SEER numbers represent the potential efficiency of an HVAC unit. They are not exact measurements that will determine how the HVAC unit will perform in your home.

Factors such as the climate of your geographical area, the size of your home and the quality of your air ducts can determine the actual SEER performance of your unit. At any rate of performance, it will not be less than SEER-13.

Purchasing a New Unit
Before you go to your local ‘big box’ hardware store to purchase a unit with the highest SEER number possible, there are factors that should be considered.

  • HVAC units should be purchased according to the size that is right for your home.
  • High SEER numbers may not be appropriate for your heating and cooling needs.
  • HVAC efficiency can be affected if it is improperly installed.
  • Regular maintenance affects your actual SEER number.

Installing Your New HVAC Unit
You might be tempted to install the unit yourself or get it installed by a family friend who performs unlicensed HVAC work. Resist the urge to do so.

Since your HVAC's SEER number and efficiency will be affected by improper installation, you should hire an HVAC company using the following guidelines. All HVAC technicians who install high-efficiency equipment should be certified and experienced.

Experienced HVAC technicians will be able to examine your home and current HVAC system to help you determine a SEER system that is appropriate for your circumstances. If you purchase a system that is not right for your home, you will lose efficiency regardless of the SEER number.

Although SEER numbers play an important role in your HVAC system's efficiency, a higher number does not mean the unit is better.

Types Of Air Purifiers for Your Home

Air purifiers are convenient household devices that, as their names suggest, purify and cleanse the air. They accomplish this by extracting contaminants from out of the air. Air purifiers can be helpful to all people but are often considered to be especially positive for those who have asthma or those who have allergies. If you're thinking about purchasing an air purifier for your residence, you should review all of the options that are available to you. You can also contact our reputable family-run HVAC company for more information. Our Venice-based business has NATE certification and also is a Bryant dealer with factory authorization. When it comes to air purifiers, we truly know our stuff.

There are numerous options are effective whole-house filters.

Pleated filters are one option. These types of filters are adept at obstructing microscopic particles that are particularly harmful to the lung tissue. If this sounds interesting to you, look for a pleated filter that's electrostatically charged. These kinds of pleated filters are terrific for drawing in typical allergens such as pet dander and pollen. Although these filters sometimes cost a bit more than others, they're generally totally worth the extra money.

Ultraviolet filters are also available. These whole-house filters are a smart option for those who are generally most concerned about the presence of germs. Ultraviolet light is capable of destroying airborne viruses and bacteria. As a result, UV filters are particularly common sights in medical facilities such as hospitals. If you ever happen to visit the tuberculosis section of a hospital, you'll likely see an ultraviolet air filter there.

Electronic filters are yet another strong option in whole-house filters. Another common name for the electronic filter is "electrostatic precipitator." These filters are often integrated into ductwork. When air travels within these filters, single high-voltage currents place electrical charges on the particles. Collector plates with opposite charges then retrieve the particles. These collector plates are situated on the units' other sides. These types of filters are particularly useful for tiny smoke particles. When smoke particles are excessively tiny and therefore cannot be caught inside of media filters, electronic filters are a good idea. These filters differ from media filters in that they don't call for replacements ever. It is important, however, for people who have electronic filters to clean their aluminum collector plates several times a year. These collector plates require cleaning with soapy H20.

Extended media filters, last but not least, are yet another choice in whole-house filters. These filters are shaped like boxes. They consist of filtration media heaps that, as a result, enable them to be stronger and more successful than standard fiberglass filters. If you want to invest in an extended media filter for your residence, you have to get it professionally installed. Extended media filters require annual replacement.

Since maintaining clean air in the home is such an important thing, it's crucial for homeowners to take the process of selecting a whole-house filter extremely seriously. Your goal should be to invest in a whole-house filter that's capable of efficiently retrieving pollen and dust, for example.

As far as the subject of air purification goes, no other company in the Venice, Florida area can assist you better than we can. If you have any questions or concerns regarding air purifiers and whole-house filters, for example, we can provide you with all of the information you could ever possibly need.

fall maintenance tips for air conditioners mahle cool air of venice florida serving north port and englewood florida

Fall Maintenance Tips for Central Air Conditioners in FL

As the cooler air approaches, many homeowners feel a little overwhelmed with everything there is to do to prepare for the change. The one thing you can relax about, though, is your central air conditioner. These do need fall maintenance performed, but the fact is that it is not a difficult task to accomplish. However, ignoring the needs of your AC could leave you stranded when the hot weather comes back. By taking care of it now, you can make sure you and your family will stay cool next summer.

Cool Air Fall Maintenance

First and foremost, if you have a central air conditioner, you will need to call in a professional to perform an inspection on it. This routine maintenance will include a cleaning. While you may be able to change a filter or clean them when needed, many of the parts that need to be inspected and cleaned are actually inside the sealed unit. The professional, who has received the proper training and has the proper tools, will be able to get inside the unit to inspect and clean it.

A professional inspection of your central air conditioner will include a thorough cleaning of the evaporator coil which is located in the part of the unit located inside your home. This is the part that actually cools the air and, if it is clogged with dust and dirt, you may notice that your unit has restricted air flow. In other words, it is not putting out as much cool air as it normally does.

They will also inspect the condenser unit located outside your home. A problem with the condenser will greatly affect the temperatures in your home. Many issues are caused by outside debris getting inside the unit or a low refrigerant level. As this unit is complex and sealed, the professional should be the one to clean it and perform any routine maintenance. Part of their inspection will also include a cleaning of the fan located inside this outside unit.

If you were to simply shut off your central air conditioning unit this fall and turn it back on in the spring, you may be lucky and nothing would be amiss. Unfortunately, this is not often the case. A lot of dirt and debris can get trapped inside air conditioning units while they are in use and, if left this way, it will cause damage when they first start back up. Even if you do not notice anything immediately, over time, you will see symptoms, including reduced air flow.

A common problem among busy homeowners is that they forget to call to have maintenance performed on their system. One solution to this problem is the air conditioning maintenance plan. The plan includes a thorough inspection and cleaning of your central air conditioning unit, and it affords you the luxury of receiving priority when you call in an emergency. If you do find that your system needs servicing, you will receive a discount for having purchased a maintenance plan.

With the colder season arriving soon in Florida, the last thing you want to do is forget about your air conditioner as you will need it as soon as the weather changes again. In fact, living in Florida offers you that chance that you still may need to have your central air conditioning on in the winter. By performing routine maintenance on it this fall, you can be certain that it will be ready to go whenever you need it. Furthermore, by keeping your central air conditioner in good working order, you can save money as it will be more efficient to operate. Call or Text us today for more details (941) 203-7955 and don't forget to check out our specials on a central air conditioner and heating maintenance. Stay Cool with Mahle!

Is Duct Cleaning a Waste of Money?

save money ac duct cleaningSo many people want to know if duct cleaning is a waste of money. Commercial cleaning firms, health studies and scientific journals conclude that the heating, ventilating, and air-conditioning system in a home and building is probably a good idea. Duct cleaning usually involves a complete cleaning of the HVAC’s air handler, coils, grilles, housings, fans and motors. Cleaning air handling units, heating and cooling coils, and air handling units can improve running efficiency.

Reports by the National Institutes of Health say there is not enough proof to determine if duct cleaning actually improves inner air quality (IAQ) or building occupant health. The following information may help you to decide if your home will benefit from HVAC duct cleaning.

Professional Duct Cleaning

Professional duct cleaners use brushes, vacuums and specially-designed blowers to clean the return, supply, and intact ducts throughout the home. Duct cleaning should be thorough, and should include a cleaning of the coils, air handler, housings, registers, motors, grilles and fans of the system. Although the jury is still out about whether duct cleaning improves air quality and helps people with respiratory allergies and illness, some states make HVAC duct cleaning a routine part of public buildings.

If duct cleaning isn’t proven to be necessary, there are instances in which cleaning ducts and the HVAC system may be important.

Indoor Air Quality

There are many growing environmental concerns in our world and it is a relatively simple task to convince people that ducts in their home require cleaning. Most homeowners value safety and cleanliness at home and paying to have the HVAC unit cleaned represents is not a major expenditure.

HVAC Contamination

In contrast, Environmental Protection Agency (EPA) says that cleaning is only necessary if the HVAC unit and its ducts are deemed “contaminated.” Since many homeowners may not know if mold is present in the HVAC system without an inspection, they may put off a decision about duct cleaning. Importantly, the State of Florida reports that mold is a serious problem. Mold requires only "a suitable place to grow, nutrients [e.g. dust] and moisture" to grow. Homeowners in Florida may believe that regular duct cleaning is an important preventive measure.

When to Clean Ducts and the HVAC System
While duct cleaning alone doesn’t seem that necessary, there are cases where cleaning the HVAC unit and ductwork could be useful. Consider HVAC unit and duct cleaning:

-- After a home modeling [especially important when high dust levels, asbestos abatement, and removal of lead paint occur]. Before performing such work, close off the ducts to prevent these dangerous elements from entering the home circulatory system.

-- After removing animals, such as rodents, found nesting in the HVAC and ducts. Cleaning in the aftermath of extermination is an important sanitary step.

-- When mold is present. Consider mold a serious problem.

-- When someone in the home is ill or suffering from a mystery allergy or respiratory illness.

-- When contaminates, such as pet hair, particulate debris, or odors are released through previously cleaned/vacuumed registers. The problem may rest within the duct system.

Disreputable Cleaning Firms

As with almost any business, disreputable firms--scammers--do exist. Homeowners should not give in to fear tactics used to get them to purchase duct cleaning services. To protect against scammer businesses, consider these details:

-- Ask for at least three references and call them. Ask each reference if they are satisfied with the business service.
-- Demand full-service cleaning of the heating and cooling unit. Cleaning the ducts is not enough.
-- Discard "specials" that offer discount duct cleaning. This type of offer allows the scammer to get a foot in the door. The goal is to sell additional products or services. A thorough cleaning requires special equipment and more than a single worker. The cost of professional HVAC unit and duct cleaning is about $500.
-- Obtain a firm estimate from any business offering cleaning of the heating, ventilating, and air-conditioning system. A reliable business will provide a preliminary inspection as well as a written estimate.

The Fine Print

Hire only National Air Duct Cleaners Association-certified (NADCA) businesses. Licensing and insurance protect the homeowner against defects in labor and workmanship. NADCA-certified businesses will follow guidelines established by the North American Insulation Manufacturers Association (NAIMA). This is crucial when insulated ducts are cleaned. The business should provide the homeowner with a visual inspection of their work to ensure your satisfaction. The visual inspection enables the homeowner to inspect each duct in person or via remote camera. The homeowner may withhold payment until the visual inspection is complete. Any use of steam is contraindicated because these treatments add moisture. Sprays or sealants should not be used and may infuse toxic chemicals into the system. At present, the EPA has not registered any chemicals for use in HVAC and duct cleaning.


Duct cleaning performed by a reputable professional cleaner may be helpful in many situations.

Simple Ways To Keep Your Home Cooler And More Comfortable While Saving Money

In many cases even a properly sized, installed and operating central air conditioner can have trouble keeping a home cool, or at least having to run longer than it should. This results in high AC bills.

Usually the problem is caused not by one single problem but by several things that act against the air conditioner by warming the air indoors as the AC works to cool it. Below are a few of these simple to fix issues that help your AC be more effective.

Insulate Leaking Electrical Outlets.

Most people are aware that they need to maintain the weather striping that lines exterior doors and widows, but did you know electrical outlets along the outer wall of block home can leak out your cool air too? While the amount of air leaking out of the home through the outlets may be small there are a couple of reasons while this is still important. First while the leak is small, it is 24/7 - a constant trickle of cool air leaking out and warm air leaking in all day every day. The other reason is in Florida, most homes are built from cement blocks. During the day the stone blocks absorb the heat from the sun. This in tern heats the air in the space inside the blocks and between walls. Having uninsulated electrical vents allows that warm air to seem into your home.

Replace Your Air Filter Often

Changing the air filter located in the air handler one per month is one of the most important and easiest ways to keep your home cool more efficiently. For the air conditioner to work properly clean air must flow through the coil inside the air handler. If the filer is dirty, it will reduce the air flow significantly. This in turn will force you to run your AC much longer to keep your home cool in the hot summer months. Having a dirty air filter will also allow dust and dirt particles to build up in the coil and work their way back into the air of your home where it can contribute to indoor air pollution. So simply changing your AC filter regularly -at least once per month - you can keep your AC running cold and efficiently all year.

Shade Your Outdoor Unit

While it’s no surprise to anyone living in Venice, our area gets HOT. All that sunshine Florida is famous for does more than heat up your home. Direct sunlight blazing away on your outdoor air conditioner unit will get the unit extremely hot during peak sunshine hours. SO hot in fact that it can reduce the ability of the outdoor unit to exchange the heat from inside your home out into the air. The solution is a simple one -simply provide shade for your outdoor unit. By shading the unit, it will no longer be absorbing heat from direct sunlight all day long and will stay much cooler. This can improve the ability of the AC to remove heat from the coolant and in turn make your air conditioning more efficient! There are a lot of ways to can shade your air conditioner ranging from building an awning like structure to simply planting a shade tree or large shrub near by. Of you do choose the tree method, though make sure tree will not drop leaves and seeds into your outdoor unit and that you maintain plenty of open space around the unit for air to flow.

Shade Your Windows

While not really a cheap solution, shading your windows from the outside will help quite a bit. This is because even if you have curtains or blinds inside the sunlight is still passing thermal radiation into your curtains and blinds. After the blinds heat up they will release that heat into your home. Depending on how your home is oriented this can result in a significant heat source. By shading your windows from the outside you prevent the curtains and blinds from ever heating up and warming the inside of your home. Shading you windows can be accomplished a variety of ways from planting shrubs or shade trees, to having awnings installed or even films applied to the window to block out the heat.

By performing a few maintenance tasks around the home you can really make your air conditioner have to work less to keep you cool. However if even after these measures are taken your AC is still struggling to cool your home give us a call and we will be there to fix your ac in a flash.

One of the biggest issues for a poorly working central air conditioning system is not changing, or worse, not even having an air filter in the air handler.

Why an air filter is so important for central air conditioners

So what’s the big deal with the air filter anyway? It comes down to how the vast majority of air conditioning systems have been designed. Nearly all air handlers which deliver cold coolant and also absorb heat from the home, have air flowing over a coiled line of coolant.

This coiled tube which contains coolant, is embedded in a honey-comb like structure of very narrowly spaced cooling fins. For proper operation it is essential that air can flow through and around this coil.

As air is drawn over the coil is gets cooled by the coolant and blown into the air vents by a blower. In addition to cooling the air, the air actually heats the coolant in the same way ice melts in a class of water. But also with a cold drink, condensation will form along the coil and when operating properly, will drain away and out of the home.

However if the air flowing over the coil and the finely spaced cooling fins is dirty with dust particles and other common particulate in household air, the dust will begin to build up around both the coil and the blower fan.

Over time the dust will clog up the cooling fins on the coil and prevent air from flowing directly over the coil. Not only does this prevent the air from being fully cooled it causes another issue, the water from condensation does not fully drain away.

During hot days the homeowner will run the air conditioner much harder because the clogged coil is not able to cool the air fully.

As more and more condensation builds up in the dust coating the coil and other AC parts, the coolant which is no longer being warmed by the air will actually get the condensation so cold it will freeze solid.

Once this happens the air conditioner will cease to cool the air at all because air can no longer reach the coil and exchange heat. The only remedy at this point is to shut the AC off and let the ice met away.

Often the issues goes unnoticed for years causing the air conditioner to be run much more often than needed and resulting in much higher electric bills.

The get and keep an older dirty AC back to good running order give Mahle Cool Air a call. We can completely clean out the air handler parts allowing the air to be cooled like new and all that condensation to be drained away. After that be sure to change your air filter each month to keep the air flowing clean and free of dust. If if need some help in this area Mahle Cool Air offers regular maintenance plans to keep your AC running smooth all year long.

Why Do Air Conditioners Breakdown In Summer?

As summer approaches, residents here in Florida will be using their air conditioner more frequently, and it is going to be operating for longer periods of time. This is when system breakdowns are most likely to occur. In most cases, repair of the unit or replacement of a specific part is necessary, and this means calling on the services of an experienced HVAC tech.

You certainly don't want to think about the possibility of a 90° home or office interior, but it just might happen. It is, therefore, a good idea to learn about why your air conditioning unit might fail. Here are some of the most common reasons an HVAC unit experiences problems during the late spring and summer seasons.

1) Motor Capacitors Become Inoperative
As you run your air conditioner more and more, overheating of the unit often causes the capacitors to become fatigued. If they blow out, the motors that run the compressor and fans will not operate. The system won't even circulate the room air, meaning that your home's or office's interior will heat up very quickly. A large air conditioning unit that provides a high number BTU's cooling power can cause an electrical overload, and instead of the breaker panel tripping, the capacitors on the system's motors will blow.

2) Refrigerant Leak
As you operate your air conditioner more and more frequently, the cooling refrigerant begins to circulate under more pressure. Coolant is sent to the outdoor compressor and then rerouted back to the central unit. If a leak develops, the refrigerant loss can become an indoor or outdoor environmental hazard. At the same time, you will notice that the air coming from the register ducts is no longer cool. The only way to fix this problem is to have a professional HVAC system tech fix the leak and replace the refrigerant.

3) Coils Become Frozen
This is one of the most common air conditioning system problems. As the unit runs, dirty filters or blocked ducts can cause a cooling of the evaporator coils. Sludgy refrigerant is the result, and the coils will become covered with a thick layer of ice or frost. The coils will no longer conduct heat away from the air flow, and the result is warm air blowing from the registers. If the refrigerant lines become blocked, they must be cleaned out by a service technician.

4) Faulty Thermostat Operation
If your thermostat is set to the desired temperature but the system keeps cycling on and off, chances are the thermostat has a faulty part or there is a wiring problem. Repeated cycling can cause a series of problems within the evaporator coils as well as to the motors and fans. Replacement of the thermostat may be necessary.

Most air conditioning repairs become more and more expensive if the problem is allowed to continue. The sooner the unit is repaired, the lest costly the repair bill.
