Heat Pump Maintenance Dallas TX

Signs Your Heat Pump Needs Maintenance

Heat pumps usually give plenty of warning before they break down. Call us if you notice any of the following:

• Auxiliary Heat on Mild Days: Backup heat is normal below freezing. If your thermostat shows AUX or EM heat on a 45-degree day, your heat pump is not carrying its share of the load, and your electric bill will show it.
• Ice That Will Not Clear: Light frost in cold weather is normal, and the defrost cycle should melt it off. A unit that stays encased in ice points to a defrost, airflow, or refrigerant problem.
• Cool Air in Heating Mode: Heat pump air feels milder than furnace air. Air that feels cool at the vents for long stretches outside of a defrost cycle is a sign something is wrong.
• Stuck in One Mode: A heat pump that will not switch between heating and cooling may have a failing reversing valve or a control problem.
• Short Cycling: A system that turns on and off every few minutes wastes energy and wears out the compressor early.
• Unusual Noises: Grinding, screeching, or rattling from the outdoor unit usually means a motor or loose part needs attention. A brief whoosh during defrost is normal.

1. 01

   Outdoor Coil Cleaning

   We clear leaves, grass clippings, and cottonwood fluff from the outdoor coil so the system can move heat efficiently in both directions.

2. 02

   Refrigerant Charge Check

   We verify the refrigerant charge. Low refrigerant hurts heating and cooling alike, and it usually points to a leak that needs to be found and repaired.

3. 03

   Reversing Valve Test

   We run the system in heating and cooling modes to confirm the reversing valve shifts cleanly between them.

4. 04

   Defrost Control Check

   We test the defrost board and sensors so the outdoor unit clears frost on its own during cold weather.

5. 05

   Auxiliary Heat Strip Test

   We test your backup electric heat strips and their controls so they are ready when temperatures drop below freezing.

6. 06

   Electrical Components

   We test the capacitors and contactor and tighten electrical connections, the parts most likely to fail during a heat wave or a cold snap.

7. 07

   Indoor Coil, Blower, and Drain

   We inspect the indoor coil, test the blower motor, and clear the condensate drain line to prevent summer water leaks.

8. 08

   Thermostat Settings

   We confirm your thermostat is set up for a heat pump, including the auxiliary heat settings that affect your winter electric bill.

9. 09

   Filter and Airflow

   We check or replace your filter and confirm strong, even airflow through your vents.
