Answers to Common Questions
View All FAQsWhy Is My Heat Pump Running But Not Cooling Properly?
A heat pump that runs but won’t cool usually has restricted airflow, an incorrect thermostat setting, dirty coils or filters, or a refrigerant issue. Change or clean the filter monthly. Our EPA-certified techs measure airflow, verify refrigerant charge, check for leaks, tighten electrical terminals, and confirm thermostat operation. Schedule tune-ups twice a year in spring and fall to prevent cooling loss. We service all brands in Champaign and Urbana.
Quick checks:
- Set thermostat to Cooling and lower the setpoint.
- Replace/clean the air filter.
- Keep indoor vents and the outdoor unit clear of obstructions.

A heat pump not cooling on hot days usually means there’s a problem with refrigerant charge, airflow, controls, or the reversing valve. The most common cause we see is low refrigerant from a leak, which prevents heat from being absorbed and moved outside.
Other frequent culprits include a clogged filter or dirty indoor/outdoor coil restricting airflow, a thermostat or control issue keeping the system from switching modes, a stuck reversing valve leaving the unit in heat, or a compressor/contactor fault that stops proper operation. A technician will verify airflow, measure the refrigerant charge, check for leaks, inspect electrical connections, and confirm thermostat and control operation per our standard checklist. We handle these exact issues across the Danville area and also offer flat-rate pricing with 24/7 emergency service.
Try these quick checks before you call:
- Replace or clean the air filter if it’s dirty.
- Confirm the thermostat is set to Cool and a lower temperature than the room.
- Clear leaves or debris from around the outdoor unit so air can move freely.
If cooling doesn’t return after these checks, turn the system off and schedule a professional diagnosis to prevent further damage. <br/> Updated: 2026-04-01 <br/> Need help in Danville, IL? Call 217-559-9454 or book online.

A heat pump’s lifespan varies with maintenance, installation quality, and run time. In Champaign and Urbana, our technicians perform maintenance visits or tune-ups to verify airflow, refrigerant charge, electrical connections, and thermostat operation. Rather than a single annual visit, we recommend twice-annual maintenance checks designed to account for both heating and cooling demands. Monthly filter care and clean coils have a dramatic impact on performance and service life. We also diagnose and seal duct leaks to reduce strain.
Quick checks:
- Schedule professional service at least once a year.
- Clean/replace filters monthly; keep the outdoor unit clear of debris and landscaping materials.

There isn’t a single “average” annual price listed on our site. Your cost depends on the system, its age, and what the visit includes. We use flat-rate pricing, and a technician will confirm costs on site. Many customers join our Lanz Comfort Family for savings and twice-yearly tune-ups. We service all brands and offer 24/7 emergency response with no after-hours fee. Typical maintenance checks include refrigerant charge, airflow, electrical terminals, belts, motors, and filter/coil care.

You can handle basic heat pump upkeep, but full servicing should be done by a pro. Change or clean filters monthly. Keep the outdoor unit clear and protected from high winds. Professional annual service is recommended to measure airflow and refrigerant charge, check for leaks, seal ducts, inspect electric terminals, and verify controls and thermostat operation. DIY refrigerant or electrical work is not safe and can harm efficiency.
Quick checks you can do:
- Replace/clean filters monthly.
- Clear debris around the outdoor unit.
- Follow the manufacturer’s care instructions.
