One Call Covers the Full Job: HVAC, Electrical & More
When a new AC system also needs panel work, wiring upgrades, or other trades involved, most homeowners end up juggling two or three separate contractors. At Cornerstone Services, that problem doesn’t exist. Our HVAC, electrical, plumbing, and handyman services all operate under one roof, one warranty, and one flat-price quote, so your installation is handled start to finish without the back-and-forth.
We’ve been in business for over 20 years and have earned more than 1,250 five-star reviews across Google, HomeAdvisor, Facebook, and Yelp. Our technicians are fully licensed and insured, arrive in uniform, and drive lettered vehicles, so you know exactly who’s at your door. We serve residential and commercial customers throughout North Andover and northern Massachusetts.

AC Installation & Replacement Services We Offer
We handle central air conditioning installation and replacement for both residential and commercial properties, as well as ductless mini split installation for homes without existing ductwork. Mini split systems allow room-by-room temperature control without duct modifications, making them a practical solution for additions, older homes, and spaces where running new ductwork isn’t feasible.
Before recommending any system, we assess your home’s cooling load to match the unit to the actual demand of your space. An oversized or undersized system won’t run efficiently. Proper system sizing helps determine whether your new installation performs the way it should.
Our comprehensive AC installation services include:
- System sizing and selection: We calculate your home’s cooling load before recommending a unit, so the system is matched to your space, not just estimated.
- Central AC installation: Full installation of new central air conditioning systems for residential and commercial properties.
- Ductless mini split installation: Room-by-room cooling without ductwork. It is ideal for homes where central duct runs aren’t practical.
- Old unit removal and disposal: We remove your existing outdoor condenser and air handler responsibly, so you don’t have to arrange separate disposal.
- Full system replacement: From disconnecting the old unit to verifying refrigerant line and electrical compatibility with the new system, we handle the complete replacement process.
- Free system consultations: Not sure what your home needs? We offer complimentary consultations to walk you through your options before any commitment.
Why North Andover Homeowners Choose Cornerstone Services
There’s no shortage of HVAC contractors serving the area. What separates us is how we’re structured and how we stand behind our work.
Here’s what that looks like in practice:
- Flat-Rate, Per-Job Pricing
We price by the job, not the hour. The number we quote before work begins is the number you pay when it’s done, with no adjustments for time overruns and no fees that appear at the end. - Signed Workmanship Warranty
Every completed installation is backed by a signed warranty under our quality assurance policy. You get documented protection on our work, not just a verbal assurance. - Same-Day Scheduling Available
If you need an installation or assessment quickly, call us. We offer same-day scheduling for customers who can’t wait, and our team is available around the clock for scheduling, questions, or urgent needs. - Background-Checked Technicians
Every technician we send to your property has passed a background check before setting foot in your home or business. Uniformed, lettered-vehicle arrival means you can verify who we sent before you open the door. - On-Time Arrival, Built Into Our System
Our service vehicles are staged on call from multiple locations across the region, and we run a dedicated scheduling system designed to support on-time arrival. If we say we’ll be there, we can be there as scheduled. - Single Provider for Every Trade
AC installation often uncovers related needs: an outdated panel, a circuit that can’t support the new system, or wiring that needs to be brought up to code. Because we offer electrical, plumbing, and handyman services alongside HVAC, one call can get all of it resolved under the same warranty and pricing structure. No second contractor required.
We also offer financing options for customers who’d prefer to spread out the cost of a new system. Ask about current terms when you schedule. Monthly rotating promotions are available as well. Ask what’s running when you call. After every installation, our technicians clean up the job site before they leave.
Contact Cornerstone Services online or at (603) 874-1402 today to schedule your AC installation or replacement in North Andover.
