Most Common HVAC Service Calls in the Summer

If your HVAC system does not work properly and your home is not as comfortable as it should be, you can probably tell that there’s something wrong with your unit. While some minor works like changing the air filter seem doable, other jobs like part replacement and repair will require the professionals to bring back your HVAC system’s optimum performance.

Although the summer season is all about moderate to high temperature, many of the HVAC problems can still arise, you will need expert care. Here are the most common HVAC service calls in the summer:

Refrigerant Leaks

Leaks in your refrigerant can happen and this problem can cause your system not to work properly. If your refrigerant has leaked out, your compressor might run hot and eventually stop running. So, before the problem gets worse, be sure to call your HVAC contractor immediately.

Dirty Components

A heating and cooling system that lacks regular maintenance and cleaning cannot offer the efficiency and comfort that you and your family deserve. Dirty components can make your unit work even harder, increase your energy consumption, and might impair its longevity. Be sure to contact your local HVAC contractor to perform complete HVAC maintenance and cleaning.

Blown Fuse

The fuse is found in your evaporator coil and it protects your unit’s compressor or motor against overheating. But if there are loose or short wiring’s, the fuse may blow anytime. This problem can be very dangerous, that is why you need to call your local technician to handle the repair.

Corrosion of Terminals and Wires

If your HVAC system frequently turns on and off on its own, it could be a sign that your terminals and wires are corroded. Contact your technician to inspect your HVAC system. If the problem is in your terminals and wires, replace the corroded parts immediately.

Loud and Strange Noises

Noises are normally heard when you turn on and off your HVAC system, but the unusual squealing, rasping, banging, or grinding sounds are not part of the operation. These loud and strange noises can indicate that your system’s bearings and belts are wearing out. Sometimes, they can also mean you have dirty burners, air circulation problems or normal wear and tear. So when you hear strange noises, call your HVAC contractor for service immediately.

Frozen Coils in Summer: How is that Possible?

Frozen Coils in Summer: How is that Possible?
Is your A/C starting to freeze up this summertime? This can be caused by an ice buildup in your coils. Let’s take a closer look at how this is possible in the midst of a heat wave.

Evaporator and condenser coils—these two are responsible for the heat transfer and cooling process of your unit. When ice buildup starts to cover them, it’s a sign of trouble in your system.

Let’s find out what’s causing them to ice up.

  • Damaged Blower Fan

The blower fan is responsible for sucking the heat and bringing cool air in your home. When it gets damaged, the airflow significantly changes, and condensation starts to build up in your coils. Immediate attention is required to avoid further costs in your system.

  • Clogged Air Filters

Clogged air filters are another reason for frozen coils. How? Dirt, mold, and other airborne pollutants can obstruct the air in your air conditioner. If the air is stuck around the coils, it will start to freeze up and cause your system to breakdown. So, check your air filters regularly and replace it periodically.

  • Faulty Thermostat

The thermostat can make or break your system. If your thermostat is not working properly, your A/C will work harder or runs too cold. Ice can also build up in your coils. If you’re still using the old manual-dial type, consider recalibrating or switching to a programmable thermostat. If you need expert’s advice, feel free to contact us at Kirk Air Conditioning and Heating.

  • Dirty Condenser

Your outside unit is called the condenser, which is often left unchecked and uncleaned. Dirt, mold, and other debris negatively affect the cooling process of your system, causing ice buildup in your coils too. These extra loads are causing your A/C to overheat and reduce its lifespan.  Make sure to check and clean your condenser regularly. Use soft brush and gently remove these filthy particles or use water to wash it off.

  • Refrigerant Issues

Refrigerant is a chemical involved in cooling your home, and having issues with it can harm your health. The low refrigerant level is another reason for frozen coils. Refrigerant leaks can damage your system, leading to costly repairs. Do not ignore this red flag and contact the pros to get it checked and fixed immediately.
