Repair, Installation & Maintenance for Salem Homes & Businesses
When your cooling system fails in the middle of a New Hampshire summer, you need a provider that shows up fast and works to get it right the first time. Cornerstone Services handles AC repair, installation, and maintenance for residential and commercial customers across the region. We work on central air conditioning systems and ductless mini splits. Same-day AC service is available for customers who call and need help quickly.
We’re also more than an HVAC company. Electrical, plumbing, cleaning, and handyman services are all available through the same team, under the same roof. One call and one warranty cover whatever the job turns up.

AC Services We Provide
Our licensed and insured technicians work on all makes and models of cooling equipment. Whether you’re dealing with an unexpected breakdown or planning ahead for the season, here’s what we cover:
- AC Repair: Central air conditioning and ductless mini split repairs, including refrigerant issues, frozen evaporator coils, clogged condensate lines, blower motor failures, and thermostat problems.
- Seasonal Maintenance & Tune-Ups: Routine annual maintenance before the cooling season helps prevent breakdowns, maintain efficiency, and extend system life. Seasonal maintenance plans are available.
- New System Installation & Replacement: From new construction to aging system replacement, we handle full installations. When repair costs are high relative to your system’s age, we can give you an honest assessment of whether replacement makes more sense.
- Ductless Mini Split Installation: We install ductless mini split systems for homes and businesses without existing ductwork, or for customers adding cooling to a specific area.
- Emergency AC Repair: Our team is on call around the clock. If your system goes down overnight or on a weekend, we’re available.
Why Salem Customers Choose Cornerstone Services
We price every AC job by the job, not the hour. The number we quote you before work begins is the number you pay when it’s done. Every completed job is also backed by a signed workmanship warranty under our quality assurance policy, so you have documented protection on the work we perform.
Here’s what else you get when you work with us:
- 1,250+ Five-Star Reviews: Earned across Google, HomeAdvisor, Facebook, and Yelp
- Background-Checked Workers: Every technician is screened before arriving at your property
- On-Time Arrival: Service vehicles are staged from multiple locations so we show up when we say we will

- Financing Available: Ask about current terms when you schedule
- Monthly Promotions: Rotating offers each month with savings on scheduled services
One Call Handles It All
AC work doesn’t always stay neatly within the HVAC scope. A technician pulling an older system might find ductwork damage, a thermostat wiring issue, or an electrical panel that needs attention before a new unit can be installed. With most contractors, that means a second call, a second company, and a second wait.
With Cornerstone Services, it doesn’t. Electrical, plumbing, HVAC, cleaning, and handyman services are all available through one company, under one pricing structure and one signed warranty. Our tagline says it plainly: One Call Does It All.
