Maintenance

Tune-ups that catch problems before they cost you.

A neglected system works harder, lasts fewer years, and quietly raises your utility bill. Our seasonal maintenance keeps equipment within manufacturer specs and protects your warranty coverage.

Furnace Tune-Up

Heat exchanger inspection, burner adjustment, ignition check, filter replacement, and carbon monoxide test. Recommended every fall before heating season.

From $129

AC Tune-Up

Coil cleaning, refrigerant level check, capacitor and contactor test, drain line flush, and thermostat calibration. Scheduled in spring before the first hot stretch.

From $139

Comfort Club Plan

Two visits per year (heating + cooling), 15% off all repairs, priority scheduling, and no overtime fees. Transfers to new owner if you sell the home.

$19 / month
Installations

Right-sized equipment, installed the way the manufacturer intended.

We don't guess at tonnage. Every replacement starts with a Manual J load calculation so your new furnace or condenser matches the actual heat loss and gain of your building — not a rule of thumb that leaves you with short cycling and uneven rooms.

We install gas furnaces, electric air handlers, heat pumps, ductless mini-splits, and packaged rooftop units. Most residential replacements are completed in a single day, with old equipment hauled away and the work area cleaned up before we leave.

All installations include a written warranty on labor, manufacturer warranty registration on your behalf, and a follow-up visit within the first heating and cooling season to verify performance.

Heat out at midnight? AC down on a 90° day?

Our on-call technician answers real calls, not a call center. Most emergencies are reached within 90 minutes in the Columbus metro area.
