Local HVAC Services in Oklahoma City, OK 73159 - A & A Air Conditioning Heating & Refrigeration

In Oklahoma City, a failing reversing valve often shows as your heat pump struggling to switch between heating and cooling modes, blowing lukewarm air, or making a distinct hissing noise. Since our weather demands reliable climate control, it's best to call a professional like A & A as soon as you notice these symptoms. Prompt service can prevent further system strain and restore efficient operation for your home's comfort.

For most Oklahoma City homes, we recommend checking your HVAC air filter every month and replacing it at least every 90 days. However, during high-pollen seasons in spring or dusty periods, you may need to change it monthly. A clean filter is crucial for maintaining airflow, improving indoor air quality, and preventing your system from overworking, which can lead to breakdowns and higher energy bills.

Yes, absolutely. A severely clogged filter restricts airflow over the evaporator coil, causing it to get too cold and freeze, even when it's hot outside. If you notice reduced cooling, ice on the indoor unit, or water leakage, turn the system off and check the filter first. If it's dirty, replace it and let the ice melt completely before restarting. If the problem persists, our technicians can diagnose and resolve any underlying issues to prevent damage.
