Green Tree Heating & Air Conditioning: Reliable HVAC Repair Serving Northglenn, CO 80233

Common signs include weak or no airflow from your vents, unusual humming or grinding noises from the unit, the system frequently overheating and shutting off, or a complete failure to start. In Northglenn's climate, dust and strain can accelerate wear. If you notice these issues, it's best to call for a diagnostic to prevent a complete breakdown.

It could be. A faulty reversing valve, which switches your system between heating and cooling, is a common culprit. Other signs include the system stuck in one mode or unusual hissing sounds. Given the heavy use of heat pumps in our area, valve issues are frequent. Our technicians can test the valve's solenoid and refrigerant pressure to pinpoint and resolve the problem.

Regular maintenance is key. We recommend bi-annual tune-ups before summer and winter. This includes cleaning components prone to dust buildup (a major factor in blower motor failure), checking refrigerant levels, and testing electrical components like the reversing valve solenoid. This proactive care can identify small issues before they lead to costly repairs and keep your system efficient.
