Dover HVAC keeps local homes comfortable with experienced technicians, stocked trucks that finish most repairs in one visit, and upfront, honest pricing on every job.
A broken AC or furnace doesn't wait, and neither should your service company. With technicians based around the Dover area, we provide fast, reliable service and hands-on care from experienced pros who know the climate and housing stock of our region.
When the air conditioning quits or the furnace won't light, you need a technician who finds the real problem and fixes it the same day.
When your AC hums but won't cool, blows warm air, or keeps tripping the breaker, the fix is usually a single worn component. We test the system, find it, and replace it, often the same day. Every repair comes with an upfront quote and an honest opinion on repair versus replacement.
When the furnace clicks but never lights, lights and shuts off, or runs without warming the house, the cause is usually one component. We test the ignition, airflow, and safety controls to find it. We also check for the problems that matter for safety, like a cracked heat exchanger, and give you an upfront price before any work begins.
We take on the full range of comfort problems, from failed capacitors and cracked heat exchangers to ductless installs and commercial rooftop units, with the hands-on experience the job calls for.

Call (351) 345-9323Most failures start small and give you clues first. Below are the warning signs local homeowners run into most, and any one of them is reason enough to call us for a closer look.
Warm air from the vents usually traces to a weak capacitor, a refrigerant leak, or a frozen coil, all fixable, and all diagnosable in one visit.
AC repairFrequent on-off cycling is the furnace protecting itself from a real problem. Ignoring it risks the heat exchanger, the most expensive part in the cabinet.
Furnace repairA system that runs constantly but never satisfies the thermostat is burning money. Seasonal maintenance restores the efficiency you paid for.
Maintenance & tune-upsR-22 refrigerant, rust on the cabinet, a compressor on its second capacitor, these are signs the smart money is on replacement.
System replacementYour ducts move the same air thousands of times a day. Years of dust, dander, and construction debris ride along until they're cleaned out.
Air duct cleaningA garage office, a converted attic, or that one bedroom the ducts never reached, a ductless mini-split solves it without tearing open walls.
Mini-split installationAn HVAC system never fails at a convenient time. We schedule fast, show up on time, and arrive with the parts to finish the job.
We don't cut corners. Our team is experienced, background-checked, and fluent in every major brand, from a 20-year-old gas furnace to the newest inverter-driven heat pump.
If a $40 capacitor fixes it, that's what we'll tell you. We quote repair and replacement honestly, with real numbers, and let you choose, no scare tactics, no pressure.
Installations get the full treatment, real load calculation, correct line sets, sealed and balanced ductwork connections, and a complete commissioning test before we leave.
For over 12 years, Dover HVAC has been the go-to team for HVAC service in this part of NH. Our locally based technicians know the specific conditions that local comfort systems face, from the age of local housing stock and its ductwork quirks to coastal air that corrodes condenser coils.
Our team doesn't just swap parts and leave. We check the airflow, the charge, and the electrical supply driving the failure common to local homes and businesses. This local knowledge means we catch problems other companies miss and keep your home comfortable.
Speak directly with a local HVAC expert. Upfront pricing, no obligation.
From the first call to the final airflow check, our method is built to solve the problem completely the first time.

We don't guess. The diagnostic covers the full system and turns into a straightforward recommendation with the cost spelled out up front.
Whether it's a ten-minute capacitor swap or a full system changeout, the work is done carefully, tested thoroughly, and left cleaner than we found it.
To keep your comfort reliable long-term, we can set up seasonal maintenance that cleans coils, checks the charge, and catches small issues before they strand you in the wrong season.

A house with no AC in a heat wave isn't something to wait out. Here's what our team does the moment you call to restore your comfort fast.
The first call is where it all starts. Someone on our team picks up, works out how urgent the situation is, and schedules the soonest visit available, while telling you the few simple things to do in the meantime.
Your technician shows up ready to work, not just to look. The common failure parts ride on every truck, so the visit moves straight from diagnosis into repair.
During the visit, the cause gets found and fixed. Our technician works through electrical, refrigerant, and airflow checks and shows you exactly what failed and why.
We offer spring and fall tune-up plans, with reminders when you're due, to clean coils and test components before they cost you a compressor. Staying ahead of the problem is how equipment reaches year 15 and beyond.
"When our old furnace was on its last legs, they walked us through converting to a heat pump instead of just quoting a like-for-like swap. Our winter bills dropped noticeably the first season, and we got cooling out of the same equipment. Zero regrets on this one."
"The AC would run for hours and never hit the set temperature. Their tech found a refrigerant leak at a valve, repaired it, and recharged the system properly instead of just topping it off like the last guy. It has kept up through every heat wave since."
"We put a ductless mini-split in the bonus room over the garage that no vent had ever reached. They measured and calculated instead of eyeballing it, and the install was clean and quick. That room is finally usable year-round."
We do more than patch the symptom. We give you lasting comfort. Every visit is backed by experienced technicians, quality parts, and a focus on fixing the cause.
The difference shows up in the results. Our technicians have logged real years on these systems, so they identify the actual fault the first time and fix it properly instead of throwing parts at your system until something sticks.
We size every replacement to an actual load calculation rather than defaulting to whatever's on the truck. Installations get done to code: sealed duct connections, correct line sets, proper condensate handling, clean electrical work. You get a system that performs for years, not just on day one.
Our team focuses on keeping systems alive with simple, scheduled care. If you want to avoid the emergency replacement, our seasonal tune-up plans clean coils, verify the charge, and test every safety control. No surprises, no hidden fees. This focus on longevity is why so many homeowners recommend us.
Wherever you are in our service area, we've got it covered, with fast repairs, quality installs, and maintenance plans reaching every community on our list.
