What Are The Most Common HVAC Problems In The Summer?

HVAC stands for heating, ventilation, and air conditioning. And in Florida’s summers – air conditioning is the most important out of all of them. As an HVAC company with over 12 years of experience in Bradenton, the summertime is one of our busiest seasons.

The last thing our customers want is for their AC to break down when it’s 90 degrees outside and have to call us to repair it for them. Which begs the question, what are the most common HVAC problems in the summer?

From over a decade of experience, here’s our list and what to watch out for:

1. Refrigerant Leaks

    Refrigerants are chemical compounds used in air conditioning systems, refrigerators, and freezers. They’re there to absorb heat and provide cooling. It transitions between liquid and gaseous states within the HVAC system, effectively transferring heat from the indoor air to the outside.

    In an HVAC system, refrigerant cycles through a closed loop. It starts as a low-pressure gas, then is compressed by the air conditioner’s compressor, which increases its temperature and pressure. 

    The refrigerant then flows through the condenser coils where it loses heat to the outside air and condenses into a high-pressure liquid. This liquid passes through an expansion valve, where it experiences a drop in pressure, turning it into a low-pressure liquid/gas mixture. 

    Leaks happen due to corrosion or damage to the refrigerant lines. Signs of a refrigerant leak include reduced cooling power, hissing noises from the HVAC unit, and higher than usual energy bills.

    You should fix leaks quickly since low refrigerant levels can strain the compressor, leading to way more issues down the road.

    2. Dirty Air Filters

      Air filters in HVAC systems means protection from dust, hair, and other particulates that can accumulate and cause damage. By trapping these nasties, filters prevent them from entering the system where they can clog the internal mechanisms, such as the evaporator and condenser coils, and reduce the system’s efficiency and lifespan.

      Air filters also improve the air quality inside a building. They capture pollutants, allergens, and particulates from the air, such as pollen, dust mites, and pet dander, which can be beneficial for people with allergies or respiratory issues.

      High-efficiency particulate (HEPA) filters are super effective at capturing very fine particles, significantly enhancing indoor air quality. During Florida summers, when the HVAC system is used more frequently, filters can become clogged faster. This restricts airflow, forcing the system to work harder and less efficiently. 

      We’ve made quite a few house calls in Bradenton for HVAC repairs because of this – which is why it’s so important you check for dirty air filters before they become a problem.

      3. Faulty Thermostats

        Sometimes it’s not 100 degrees in Florida – it could be that your thermostat is wrong! A malfunctioning thermostat can lead to issues with maintaining comfortable temperatures.

        Common problems include unresponsive thermostat screens or incorrect temperature readings, which can cause the HVAC system to run excessively or insufficiently.  Almost like when a friend tells you it’s hot outside even when it’s cold, so you forget to bring a coat.

        If your HVAC system is linked to a thermostat and it’s giving it the wrong info, this means that your system can run far longer than it should, leading to crazy electricity bills. Making sure your thermostat is properly calibrated and functioning can save you from discomfort and high energy costs during summer.

        4. Overworked Air Conditioners

          The strain on air conditioners during Florida’s hot months is challenging. For instance, an HVAC unit in Sarasota failed during a heatwave because it was overworked and hadn’t been serviced beforehand. Overworked HVAC units are one of the most common reasons we’re called out during a heatwave in Florida.

          The repair required was extensive and costly when it didn’t have to be. You should do a pre-summer servicing to check system components like the compressor and condenser for any signs of wear or damage that could lead to breakdowns during critical times.

          This is one of those situations where you’d rather get your engine checked before driving onto the highway. Or in this instance, having an AC run 24/7 in the Florida heat. Not to mention the crazy high energy bills since your AC unit runs extra hard to compensate for the loss of efficiency.

          5. Drainage Problems

          Florida summers don’t just get hot – they also get humid. Fortunately, most HVAC systems have ways of dealing with this humidity and added water it gives to its system. These are called “drainage systems”.

          But if the drain line becomes clogged, it can lead to water damage and affect indoor humidity levels. You should perform regular maintenance to help keep the drainage system clear.

          Drainage issues quickly escalate from a minor nuisance to a major problem involving water damage to your home’s structure or interior. Regular cleaning of the condensate line, perhaps with a simple mixture of vinegar and water, can prevent algae and mold buildup that often clogs the pipes.

          Florida homeowners should also make sure that the drain pan is not damaged and that it properly channels the condensate away from the HVAC system and the home’s foundation.

          Lots of Things Can Go Wrong With Your HVAC System This Summer

          From drainage systems not working well, to wonky thermostats and more.
