HVAC Services We Offer in Andover
We handle heating and cooling across the full range of systems found in Andover homes and businesses. Our technicians work with all major brands and models, and our services cover both new installations and existing equipment that needs repair or upkeep.
Heating services include:
- Furnace repair and installation
- Boiler installation and repair
- Heat pump repair and installation
- Heating system maintenance
Cooling services include:
- Air conditioning repair and installation
- Ductless mini split installation
- AC maintenance and tune-ups
Additional HVAC services include:
- Air duct cleaning

Andover winters push furnaces and boilers hard, and our summers aren’t mild either. Ductless mini splits are a strong fit for older homes without existing ductwork or for adding a zone to a newer addition. Heat pumps handle both heating and cooling from a single system, which is why they’re becoming a common upgrade across New England. We’ve been working in the HVAC industry for over two decades, and we bring that experience to every service call in Andover, MA.
What Sets Cornerstone Services Apart?
We built Cornerstone Services on a straightforward principle: genuine, unwavering dedication to every client. That shows up in the details people don’t always think to ask about until something goes wrong.
Per-Job Pricing
We price by the job, not by the hour. The number we quote before starting is the number you pay when we finish: no adjustments, no hourly overruns, no hidden fees. You know what you’re agreeing to before we pick up a tool.
Signed Workmanship Warranty
Every completed job comes with a signed warranty under our quality assurance policy. That’s documented protection on our work, not a verbal assurance.
1,250+ Five-Star Reviews
We’ve earned more than 1,250 five-star reviews across Google, HomeAdvisor, Facebook, and Yelp. That track record was built one job at a time across multiple platforms.
Same-Day Service and Staged Vehicles
We offer same-day scheduling for customers who need help quickly. Our service vehicles are staged on-call from multiple locations, so we’re not starting the clock from a single dispatch point. When we say we’ll be there, we aim to show up as scheduled.
Background-Checked Workers
Every technician we send to your property has passed a background check before setting foot inside your home or business.
Clean Job Sites
Our technicians clean up when the work is done. You won’t be left with debris or materials on the floor after an HVAC installation or repair.
24/7 On-Call Staff
Our team is reachable around the clock for scheduling, questions, or urgent service needs. Financing options are also available. Ask about current terms when you call. Monthly promotional offers rotate, so it’s worth asking what’s available when you schedule.
One Call for HVAC, Electrical, Plumbing, & More
Most homeowners have dealt with coordinating multiple contractors for different jobs, one crew for the HVAC, another for the electrical, and someone else for plumbing. Cornerstone Services handles all of it under one roof, one call, and one consistent warranty and pricing structure. You’re not managing separate schedules or comparing invoices from different companies.
For local property managers overseeing multiple systems, this matters even more. A single provider handling HVAC alongside electrical and plumbing reduces scheduling friction and keeps workmanship standards consistent across every trade.
We also offer a dedicated home modifications service line that includes wheelchair ramp installation, grab bar installation, stairlift installation, kitchen modifications for elderly residents, and smart home setup for elderly and disabled clients. For households where comfort and accessibility upgrades go hand in hand, having one provider handle both simplifies the whole process.
Frequently Asked Questions
Do You Offer Same-Day HVAC Service in Andover, MA?
Yes. We offer same-day scheduling for customers who need fast help. Availability depends on the current day’s schedule, so call us at (603) 874-1402 and we can confirm what we can get on the calendar for you.
How Do I Know If I Should Repair or Replace My HVAC System?
It depends on the system’s age, how often it’s needed repairs recently, its current efficiency, and how the repair cost compares to replacement value. There’s no universal rule. Our technicians can assess your equipment and walk you through the numbers so you can decide what makes sense.
Do You Offer Financing for HVAC Installations?
Yes, financing options are available. Specific terms can change, so ask about current options when you call to schedule. We can make sure you understand what’s available before committing to anything.
How Often Should I Schedule HVAC Maintenance?
Twice a year is the standard recommendation. Fall is a good time to service heating systems before the cold hits, and spring is the right window for cooling systems before summer demand peaks. Regular maintenance helps extend equipment life and catch small issues before they become expensive ones.
What Counts as an HVAC Emergency?
If your system fails completely during extreme temperatures, if you suspect a gas leak or carbon monoxide issue, or if the failure creates a safety risk, treat it as an emergency. Call (603) 874-1402 and we can get someone to you.
