Common Summertime HVAC Problems and How to Prevent Them

As the temperatures rise during the summer, your HVAC (heating, ventilation, and air conditioning) system becomes vital in maintaining a comfortable indoor environment. Since AC plays a massive role in keeping homes in the U.S. and other parts of the world comfortable amid rising global temperatures, the demand for air conditioning will surge by 2050. 

The increased workload of the AC unit in the summer can also lead to various issues that may disrupt its efficiency and performance. The key to dealing with the most common summertime HVAC problems is learning how to prevent them. Use this guide to get familiar with these problems and ensure your system operates smoothly throughout the season.

Refrigerant Leaks

Refrigerant leaks can significantly impact the cooling efficiency of your HVAC system and increase energy consumption. Common signs of a refrigerant leak include reduced cooling performance, ice buildup on the evaporator coils, and hissing sounds from the unit.

To prevent refrigerant leaks, it's essential to schedule professional HVAC maintenance regularly. Technicians can detect and repair leaks before they escalate into more significant problems, ensuring optimal system performance and efficiency. It's also essential to ensure that your system's refrigerant levels are checked and topped up as needed during routine maintenance visits. 

Air Conditioning System Malfunctions

Air conditioning system malfunctions can range from minor issues like insufficient cooling to significant problems like compressor failure. Regular maintenance is crucial in preventing these issues. Schedule annual HVAC inspections with reputable HVAC technicians from Apple Plumbing, Heating & Air before the summer season begins to identify any potential problems early on. To schedule your service, visit ApplePlumbing.com and complete a short web form with your contact information.

Once your request is received and an HVAC technician arrives for the inspection, they will check for worn-out components, clean the unit, and ensure all parts function correctly. They will also consider the dimensions of your area, your specific requirements for usage, and your financial considerations and offer you the most appropriate choices for repairing your HVAC unit.

Clogged Condensate Drain 

Your air conditioning system produces condensate during the cooling process, which needs to be drained away correctly to prevent water damage. However, over time, the condensate drain line can become clogged with dirt, algae, and debris, leading to issues such as water leakage and reduced cooling efficiency. 

To prevent this, inspect the condensate drain line periodically and clean it as needed. You can also consider installing a condensate drain pan overflow switch, which can shut off the system if the drain becomes clogged, preventing potential water damage. 

Overworked System Due to Improper Sizing

An HVAC system that is improperly sized for your home can result in increased energy consumption, uneven cooling, and premature system failure – especially during the summer months when the demand for cooling is high. 

It's crucial to have a professional HVAC contractor perform a load calculation to determine the appropriate AC unit size for your home to prevent this issue. Investing in the right-sized unit will improve comfort, enhance energy efficiency, and prolong the lifespan of your HVAC system. 

Dirty Evaporator and Condenser Coils

Dirt and debris buildup on the evaporator and condenser coils can hinder heat transfer, reducing the efficiency of your air conditioning system. Regular maintenance, including coil cleaning, is essential to prevent this problem. However, coil cleaning can be challenging and is best left to professionals with the necessary tools and expertise to perform the job effectively.

Schedule annual HVAC maintenance to ensure that your coils are clean and free from obstructions. In addition to professional cleaning, you can help prevent coil buildup by keeping the area around your outdoor unit clear of debris such as leaves, grass clippings, and dirt.
