Global Mechanical Services - Granbury's Qualified HVAC Repair

The most frequent issue we encounter in Granbury is clogged air filters due to our area's high dust levels. A dirty filter restricts airflow, forcing your system to work harder, increasing energy bills, and potentially leading to breakdowns. We recommend checking your filter monthly and changing it at least every 90 days, or more often during peak summer and winter use. As part of our maintenance plans, we ensure your filters are clean and your entire system is clear of dust buildup.

Yes, a malfunctioning reversing valve is a common culprit when a heat pump fails to change modes correctly, especially in Granbury where these systems get heavy use.

Our technicians are experts in diagnosing and repairing reversing valve issues. We'll perform a thorough inspection to confirm the problem and provide a precise, lasting repair to restore your home's comfort.
