What a Cornerstone Services Heating Maintenance Visit Covers

Our heating maintenance services cover furnaces, boilers, and heat pumps. Whether you’re running a gas forced-air system, a hydronic boiler, or a heat pump, annual preventive HVAC maintenance before the season starts is one of the most effective ways to help avoid mid-winter breakdowns and keep energy costs in check.

Every maintenance visit includes a complete system check-up. Our technicians inspect the heat exchanger for cracks and leaks. A cracked heat exchanger can allow combustion gases to enter living spaces, so this inspection is a safety priority. We test all safety controls, adjust the burner for peak efficiency, and clean key components, including the burner assembly. A clean heater runs more efficiently and can present less fire risk, so cleaning is built into every visit, not treated as an add-on.

Beyond the core furnace tune-up, our technicians also address:

  • Filter inspection or replacement to maintain proper airflow
  • Thermostat calibration to confirm accurate temperature control
  • Ductwork inspection for blockages or leaks that reduce efficiency
  • Heat pump servicing checks for refrigerant charge and coil condition
  • Safety control testing across limit switches and pressure controls
  • Boiler maintenance checks including expansion tank and pressure relief valve inspection

When the visit is complete, our technician cleans up the work area and leaves your property the way they found it. Every job we complete is backed by a signed workmanship warranty under our quality assurance policy. This gives you documented protection on our work, not a verbal promise. Every worker we send to your home or business has passed a background check before stepping on your property.

Why Salem Homeowners Choose Cornerstone Services for Heating Maintenance

Cornerstone Services is licensed and insured, with more than 20 years of experience serving homes and businesses across southern New Hampshire. But the reasons Salem customers come back go beyond credentials.

Our service vehicles are staged on-call from multiple locations, which means technicians reach your door when scheduled, not in a vague window that turns into an all-day wait. On-time arrival isn’t a policy statement. It’s built into how our dispatch system works. We also price by the job, not the hour. The number we quote you before the work begins is the number you pay when it’s done: no hourly overruns, no adjustments at the end of the visit, and no surprises.

Financing options are available for customers who need them. Ask about current terms when you call. We also run rotating monthly promotions that can include savings on scheduled heating maintenance, so it’s worth asking what’s current when you book.

One more thing that sets us apart: Cornerstone Services isn’t a single-trade HVAC shop. We cover electrical, plumbing, HVAC, cleaning, and handyman work under one roof. When our technician is at your home for a heating maintenance visit and you need a plumbing issue looked at or an electrical question answered, you don’t have to call a different contractor. One call handles it all: same pricing structure, same workmanship warranty, same team.
