HVAC Maintenance Plans in Vermont - Protecting Your Heating Investment

Vermont winters don’t allow for heating system surprises. A heat pump that hasn’t had its coils cleaned in three years runs at 15–20% reduced efficiency and is far more likely to fail on the coldest night of the year than one that’s been maintained. A boiler that hasn’t had its condensate drain inspected can develop a blockage that causes the system to shut down on a January morning. Maintenance contracts exist to prevent exactly those scenarios.

Prevent Costly Breakdowns with Maintenance

We started our maintenance program because our customers kept calling us for repairs that should never have happened – problems that a $200 annual visit would have caught and corrected. We now maintain 150+ heating and cooling systems across Chittenden County, and our contract customers experience significantly fewer emergency calls than our non-contract customers. That’s not a marketing claim – it’s what the data from our own service records shows.

Extend Heat Pump Life with Maintenance

A properly maintained cold-climate heat pump lasts 15–20 years; a neglected one typically fails in 8–12 years. Langlois Plumbing, Heating & AC LLC's maintenance contracts include two annual system visits, refrigerant pressure checks, coil cleaning, electrical connection inspection, and priority Langlois Plumbing, Heating & AC LLC - Website Developer Guide v6.0 Page 31 scheduling for any repairs. We currently maintain 150+ active contracts across Chittenden County.

Refrigerant pressure check (heat pumps)

Indoor and outdoor coil cleaning

Filter inspection and cleaning or replacement recommendation

Electrical connection inspection and tightening

Thermostat calibration check

Blower wheel inspection

Combustion analysis (boilers)

Written service report

Condensate drain inspection and cleaning (boilers and heat pumps)

Priority scheduling

Contract customers move to the front of the line for repair calls. During peak demand periods (January cold snaps, first hot week of summer), this matters significantly.

Discounted repair rates

Contract customers receive a 15% discount on all repair labor. Parts are billed at cost.

Maintenance for Heat Pumps

Heat pump maintenance is more detailed than boiler maintenance because heat pumps are year-round systems that switch modes seasonally. The outdoor coil accumulates debris, the indoor filter collects dust, and refrigerant pressure needs to be verified annually to catch slow leaks before they affect performance.
We clean coils with professional coil cleaner, not a garden hose – the difference matters for efficiency recovery. A dirty outdoor coil on a heat pump in Vermont conditions can reduce heating output by 10–15% at low ambient temperatures. That’s the difference between a comfortable home and a cold one at -5°F.

Maintenance for Boilers

Boiler maintenance focuses on combustion efficiency, safety, and condensate management. We check the burner’s air-to-fuel ratio and adjust for maximum efficiency. We inspect the heat exchanger for cracks. We verify that all safety controls – pressure relief valves, low-water cutoffs – function correctly. For condensing Langlois Plumbing, Heating & AC LLC – Website Developer Guide v6.0 Page 32 boilers, we inspect and clean the condensate drain, which can acidify and block if ignored.
A well-maintained boiler burns fuel more completely, produces fewer emissions, and runs at its rated efficiency. An unmaintained boiler gradually drifts lower – often 5–10% below its rated AFUE within three years.
