Get matched with top air conditioning pros in Coolidge, AZ

Q: Can running AC too cold cause mold?

• <div><p>Yes, running your air conditioning unit too cold can cause condensation in the air ducts and built up moisture on the air filter, resulting in a breeding ground for mold and mildew. Mold and mildew growth can irritate those with respiratory issues, so it&rsquo;s best to keep your AC running at a normal temperature.</p></div>

Q: How often does an HVAC system need maintenance?

• <div><p>As a general rule, you should have your HVAC system professionally serviced at least once a year, though it's best to follow the manufacturer's specific recommendations. Many experts suggest twice-yearly maintenance: once in the spring for the cooling system and once in the fall for the heating system. This is especially recommended for older units, systems with recurring issues, or heat pumps that provide both heating and cooling. Regular service, which can cost between $100 and $550, keeps the system running efficiently, helps prevent costly future repairs, and saves money on utility bills.</p></div>

Q: What should a window AC sound like?

• <div><p>A window AC unit is not completely silent. You&rsquo;ll hear the sound of air blowing, and if you put your ear right up next to the unit, you may hear a slight hiss or gurgle as the refrigerant flows through the system. That said, if your system is making a running water sound, a loud banging sound, a grinding sound, or physically vibrating, you may be facing an issue or malfunction with your AC unit.</p></div>

Q: Can an overheated compressor cause a fire?

• <div><p>Yes, it is possible. An electrical fire can break out if the compressor has inadequate ventilation. When it overheats but doesn't have a proper thermal cutout, this can cause the motor to short-circuit and catch fire. This risk is exacerbated if flammable materials, like dust and fallen leaves, are clogging the unit. The compressor overheating won't start a fire by itself, but poor maintenance and installation can increase the risk once it hits its breaking point and short-circuits.</p></div>

Q: How often should I change the filter and clean the coils to prevent freezing?

• <div><p>You should plan to change your AC unit's filter every <b>one to three months,</b> depending on the manufacturer's recommendations. You should also clean the coils at least <b>once per year</b>, but if you have pets or someone in your household has allergies, you might need to clean them more often. Fortunately, many pros will clean the coils and change the filter for you during an inspection, which you should schedule <b>once or twice per year</b>.</p></div>

"They showed up same day I made the call. They are very expensive. I paid $192.00 to correctly attach the air vent on top of the water heater. He did not use new parts. He used the same parts I had already. All he did was expand the vent with a pair of pliers and reattached it to the water heater. Too expensive."
