What Our Customers Say

value
“Maintenance plan is worth it. Friendly, courteous, and quality work.”
Preventive maintenance for HVAC systems is a scheduled tune-up and safety inspection that cleans, tests, and adjusts heating and cooling equipment to keep it efficient and reliable. Most breakdowns start with dirt buildup, clogged drains, or loose electrical connections that drive up energy use and wear parts. We perform these visits in Mahomet and surrounding Champaign–Urbana communities. Our Comfort Family memberships include one spring and one fall HVAC tune-up with priority response for repairs.
Typical tasks include:
- Clean burners/heat exchangers; verify ignition and flame.
- Tighten electrical connections; lubricate moving parts.
- Measure airflow; test thermostat; replace or provide common filters.
- Clear and treat condensate drains; complete system cleaning.
If you notice odd noises, water around the unit, or repeated shutdowns, turn the system off and call a technician.

A typical AC tune-up service includes a full system inspection, targeted component cleaning, and completion of a detailed maintenance checklist to confirm safe, efficient cooling. Most visits focus on catching wear early, removing buildup that increases strain, and verifying controls so the system starts, cools, and drains as designed. Our technicians complete these checks each spring throughout the Champaign–Urbana area and note what was tested, adjusted, or should be monitored. Technician insight: small airflow or condensate corrections during a tune-up often avert the mid-summer no-cool calls we see most. Members of our Comfort Family receive scheduled spring AC maintenance as part of their plan.
If you notice unusual noises, weak airflow, or water by the air handler before your visit, turn the unit off to prevent damage and schedule service.
