With the summer heat baking Oak Ridge, TN, you’re sure to turn to your heat pump for relief. But if you turn it on and get nothing but warm air, you have a problem. Here are some reasons your heat pump might heat in cooling mode:
Improper Thermostat Setting
If your heat pump won’t put out cold air, your thermostat is the first place to look. Ensure it’s in cooling mode and hasn’t accidentally switched off. Then, confirm that it’s not executing a schedule that overrides your manual inputs.
Clogged Air Filter
Your heat pump can’t lower the temperature in your home if its filter gets too dirty. That restricts airflow through the system and reduces cooling capacity. Remember to change your air filter every three months or whenever it’s visibly dirty.
Dirty Evaporator Coil
Ignoring a dirty air filter for too long could allow dirt to accumulate on your evaporator coil. When your system runs, a filthy coil can’t transfer heat out of your home. Only a thorough coil cleaning by an HVAC service technician will solve the problem.
Refrigerant Leak in the Heat Pump
If your refrigerant system develops a leak, it’ll diminish its cooling capacity. It could also cause a frozen evaporator coil, further reducing performance. If you suspect a leak, arrange an HVAC maintenance or repair appointment right away.
Malfunctioning Reversing Valve
Your outdoor unit contains a reversing valve that switches the system between heating and cooling modes. If that valve gets stuck or malfunctions, you could get heat in cooling mode. Only a qualified HVAC service technician can diagnose and repair issues with a reversing valve.
Professional troubleshooting is essential if your system won’t cool your home when needed. Call Melton Heating and Air whenever you need heat pump repairs in Oak Ridge, TN.
