Popa Heating & Cooling: Experienced HVAC Repair Serving Highland, IN 46322

For most Highland homes, we recommend checking your air filter every month and replacing it every 1-3 months. High pollen seasons or if you have pets may require more frequent changes. A clogged filter is a common issue here that strains your system, reduces airflow, and can lead to costly repairs. Regular replacement is a simple maintenance step we emphasize to improve efficiency and indoor air quality.

Yes, a faulty reversing valve is a common culprit for that issue in Highland. This valve directs refrigerant flow to change your system from heating to cooling mode. Symptoms include the system blowing cool air when set to heat, or getting stuck in one mode. Don't ignore it—continued operation can damage the compressor. Our technicians can quickly diagnose if it's the valve, a wiring issue, or a thermostat problem, and perform the precise repair needed.

For Highland homeowners, we generally advise considering replacement if your system is over 10-15 years old, requires frequent repairs, or your energy bills are rising significantly. An aging system struggling with our local temperature swings becomes less reliable and efficient. We provide honest assessments—if a repair like fixing a reversing valve on an old unit is a short-term fix on a failing system, we'll explain your options for a new, energy-efficient installation that offers better comfort and long-term savings.
