HVAC Services We Provide in Amesbury

Amesbury winters run cold and summers run humid, so we cover the full range of heating and cooling services homes and businesses rely on year-round.

Cooling services we handle:

Heating services we handle:

Additional HVAC services:

  • Air duct cleaning
  • Dryer vent cleaning
  • Thermostat repair and installation

Heat pumps have grown in popularity across New England because they handle both heating and cooling from one unit. Ductless mini splits offer similar flexibility for additions, older homes, or spaces where running new ductwork isn’t practical. Whatever your system, we can assess it, repair it, or replace it.

What to Expect from Cornerstone Services

A few things make working with us different from coordinating with a typical contractor.

Flat-Rate, Per-Job Pricing
We quote by the job before any work begins. That number doesn’t change at completion, no matter how long the job takes. No hourly overruns, no surprise line items.

On-Time Arrival
Our service vehicles are staged on-call from multiple locations. We built our scheduling system around showing up when we say we will, so you’re not rearranging your day around a four-hour window.

Signed Workmanship Warranty
Every job we complete is backed by a signed warranty under our quality assurance policy. You get documented coverage on the work we do.

Safety and Clean Worksites
Every technician who enters your property has passed a background check. When the job’s done, we clean up after ourselves.

Financing is available for qualifying customers, and we run rotating monthly offers that can reduce the cost of scheduled services. Ask about current terms when you call.

One Call for HVAC, Electrical, Plumbing & More

HVAC work often connects to other trades. A new system may require thermostat wiring, panel capacity checks, or boiler plumbing connections. When your provider handles all of it, you make one call instead of three and work under one warranty rather than piecing together coverage from separate contractors.

Cornerstone Services handles electrical, plumbing, HVAC, cleaning, and handyman work under the same roof. We also operate a dedicated Home Modifications division, covering wheelchair ramp installation, grab bar installation, stairlift installation, kitchen modifications for elderly residents, and smart home setup for elderly and disabled clients. We serve both residential and commercial properties in the Amesbury area, and our founding principle hasn’t changed: unwavering, genuine dedication to every client on every job.

Frequently Asked Questions

How does your flat-rate pricing work for HVAC jobs? 

We assess the work and give you a quoted price before anything starts. That price is what you pay when the job’s complete. It doesn’t change based on time on site or materials used beyond what was scoped.

Do you serve commercial properties in Amesbury, not just homes? 

Yes. We serve both residential and commercial clients in Amesbury and across northern Massachusetts. Call us to discuss your property’s specific needs.
