Cornerstone Services provides residential and commercial HVAC services in Haverhill, MA as part of a multi-trade operation covering electrical, plumbing, cleaning, and handyman work under one roof.

Our service vehicles are staged on-call from multiple locations across southern New Hampshire and northern Massachusetts so we arrive when we say we will.

Heating & Cooling Services We Provide

Haverhill’s winters demand reliable heat, and its humid summers put air conditioning to the test. We handle the full range of HVAC work for both residential and commercial properties, from first-time installations to emergency repairs on existing systems.

Our HVAC services include:

  • Furnace repair and installation
  • Boiler installation and service
  • Air conditioning repair and installation
  • Heat pump repair and installation
  • Ductless mini-split installation
  • HVAC maintenance, tune-ups, and inspections

Ductless mini-split systems are a practical fit for Haverhill homes without existing ductwork, finished additions, or rooms that need independent temperature control. Heat pumps deliver year-round comfort by handling both heating and cooling from a single system. Whatever your setup, we can assess what fits your property and get it running correctly.

Preventative maintenance is worth scheduling annually for both heating and cooling systems. A tune-up before the heating season or an AC inspection before summer helps catch developing problems before they become costly failures.

Why Haverhill Residents & Businesses Choose Cornerstone Services

More than 1,250 five-star reviews across Google, HomeAdvisor, Facebook, and Yelp reflect work done one job at a time. That track record starts with how we price and how we show up.

We price by the job, not the hour. The number we quote you is the number you pay at completion: no hourly overruns, no adjustments, no hidden fees. Every job we complete is backed by a signed warranty under our quality assurance policy, giving you documented protection on our work. Every technician we send to your property has passed a background check before arrival, and when the job is done, they clean up completely and leave your property spotless.

Our vehicles are staged from multiple locations so we arrive on time rather than making you wait. Financing options are available if you need to spread the cost of a larger installation or replacement. We also run rotating monthly promotions. Ask about current offers when you call or schedule.

One Provider for Every System in Your Home or Business

HVAC installations and repairs often involve electrical work: new circuits for equipment, disconnect boxes, and thermostat wiring. When your HVAC contractor and your electrician are the same company, that coordination disappears. We cover electrical, plumbing, HVAC, cleaning, and handyman services under one call, one warranty, and one pricing structure.

All trades operate on the same terms. There’s no separate quote process or warranty policy depending on which technician walks in. For commercial clients managing maintenance across multiple systems, fewer vendors mean fewer scheduling conflicts and clearer accountability.

Our service line also includes a dedicated home modifications division: wheelchair ramp installation, grab bar installation, stairlift installation, kitchen modifications for elderly residents, and smart home setup for elderly and disabled clients. It’s part of the same full-service model.

Frequently Asked Questions

How Do I Know Whether to Repair or Replace My System?

Age, repair frequency, and energy efficiency are the main factors. A system older than 10 to 15 years that has needed repeated repairs often costs more to maintain than to replace. If you’re unsure, our technicians can assess your system and walk you through the options with honest guidance before any work begins.

What Counts as an HVAC Emergency?

Any situation where a system failure creates a safety risk or makes the property uninhabitable. No heat during a Massachusetts winter freeze, a suspected carbon monoxide issue, or a cooling failure in extreme heat all qualify. Our on-call staff are reachable any time for urgent HVAC needs in Haverhill.
