Commercial HVAC Services We Provide
We handle the full range of commercial heating and cooling work: installation of new systems, repair of existing equipment, and scheduled preventative maintenance programs designed to reduce unplanned downtime and extend equipment lifespan. New Hampshire businesses face serious heating-season demand in winter and real cooling loads in summer, so year-round system reliability isn’t optional.
Our commercial HVAC work covers common system types, including rooftop units, split systems, heat pumps, and ductless configurations. Named services include:
- Mini split installation
- Boiler installation and service
- Commercial heating system repair
- Commercial cooling system repair
- Preventative maintenance programs
- System replacement and new installation
Same-day scheduling is available when your operation can’t afford to wait. Call us and we’ll work to get a technician out the same day.
What Salem Businesses Get When They Work with Us
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 workmanship warranty issued under our quality assurance policy. You get documented protection on our work, not just a verbal promise.
On-Time Arrival
Our service vehicles are staged on call from multiple locations across our service area. That staging is what allows us to show up when we say we will.
Background-Checked Technicians
Every worker we send to your property has passed a background check before setting foot on-site.
Clean Job Sites
Our technicians clean up after every job.
Financing & Monthly Promotions
Financing options are available for commercial work. We also run rotating monthly promotions on scheduled services. Ask about current terms when you call to schedule.
One Call for HVAC, Electrical, Plumbing & More
Commercial properties don’t divide neatly by trade. An HVAC issue can involve electrical supply, a plumbing connection, or access that requires another set of hands. When those situations come up with a single-trade contractor, you’re back on the phone finding someone else. With Cornerstone Services, you’re not coordinating multiple contractors. Electrical, plumbing, HVAC, cleaning, and handyman services are all handled by the same team, under the same per-job pricing structure and the same signed warranty.
That’s what our tagline means in practice. One call connects you to every trade we cover, with one point of accountability for all of it.
Frequently Asked Questions
Do you handle both heating and cooling systems for commercial buildings?
Yes. We install, repair, and maintain commercial heating and cooling systems, including boilers, mini splits, rooftop units, and split systems. If your building has year-round HVAC needs, we cover both sides of that work.
