What to expect from our hvac maintenance service.
Most HVAC failures don't come out of nowhere, they build up over months from dirty coils, weak capacitors, clogged drains, and refrigerant slowly drifting out of spec. Cranfield Services' maintenance visits are designed to catch every one of those before they leave you sweating in July or shivering in January. A spring AC tune-up includes a full evaporator and condenser coil inspection, refrigerant pressure check, capacitor and contactor test, condensate drain flush, blower amp-draw measurement, and a thermostat calibration. A fall heating tune-up adds combustion analysis on gas systems, heat exchanger inspection, ignitor and flame sensor cleaning, and CO testing. We document everything in writing, most manufacturer warranties require annual professional maintenance, and our reports keep that warranty enforceable. Bundle both visits and you save on each one while locking in priority scheduling when something does go wrong.
Frequently asked questions.
How often should HVAC be serviced?+
Twice a year for split systems, heating in the fall, cooling in the spring. Heat pumps, which run year-round, benefit most from twice-yearly visits.
Does maintenance really save money?+
Yes. Industry studies show well-maintained systems use 15–25% less energy and last 30–50% longer than neglected ones. Most homeowners recover the cost of a tune-up in the first season.
Will maintenance void my warranty?+
The opposite, most manufacturer warranties REQUIRE documented annual professional maintenance. We provide a written record after every visit.
