Residential HVAC in Dover, NH

Upfront Pricing

Honest, Upfront Pricing

Effective HVAC service starts with knowing exactly what you're dealing with. Dover HVAC provides honest, upfront pricing throughout Dover, handling everything from a worn capacitor to a full system replacement. Every job begins with a thorough assessment of your equipment, including its age, tonnage, fuel type, refrigerant charge, and duct condition, followed by a plain-English recommendation with the price spelled out before any work starts.

The problem with HVAC failures is that most of them develop out of sight. A pinhole leak in the evaporator coil slowly drains refrigerant, the blower bearings wear down gradually, and a weak capacitor holds on until the first hot afternoon, when the compressor won't start. If your bills are climbing, airflow drops, or ice forms on the lines, get it looked at while it's still a simple repair.

Not every visit is about a breakdown. Many Dover homeowners ask us to evaluate an aging system before it fails, and it's a smart move. With a typical AC or furnace lifespan of 12 to 18 years, replacing on your own schedule beats a rushed swap in the middle of a heat wave. We'll give you a straight answer on how much life your equipment has left.

Maintenance Plans

Tune-Ups That Keep Your System Running

The best repair is the one you never need. That's the idea behind our maintenance plans. Twice a year, we clean coils and burners, confirm the refrigerant charge, test the electrical components, inspect the heat exchanger, flush the condensate drain, and change the filter, all tailored to the equipment in your home.

We offer flexible maintenance options for homeowners, with spring cooling tune-ups and fall heating tune-ups for most systems. That's especially important in dusty areas, where dirty condenser coils choke heat rejection and drive up energy use. Each home is assessed individually, and the plan is tailored to your equipment's age, your household's comfort demands, and your local climate.

The savings add up faster than most people expect. Clean coils move heat more efficiently, a correct refrigerant charge keeps the compressor from overworking, and a fresh filter protects the blower motor. Compared with the cost of replacing a system even one year early, a maintenance plan is a bargain.

Comfort Sized to Your Home's Demand

Bigger isn't better when it comes to HVAC. An oversized unit turns on and off too often, wastes energy, and never runs long enough to pull humidity out of the air, while an undersized one runs nonstop and still can't keep up on the hottest afternoons. We don't simply copy the tonnage of the old unit. Instead, we run a proper load calculation that factors in your square footage, insulation, windows, and ductwork, and for mini-splits we size each head to the room it serves.

Choosing new equipment is about more than efficiency ratings. We'll compare furnace-and-AC setups with heat pumps, and ducted systems with ductless mini-splits, laying out operating costs, electrical and venting requirements, and the installation itself. Growing families often do best with two-stage or variable-speed equipment, which holds tighter temperatures from room to room and uses less energy. You choose what fits your home and budget.

Heating and Cooling Problems We Solve in Dover

The majority of service calls we take in Dover come down to a handful of recurring problems. The air conditioner blows warm air. The furnace won't ignite or keeps short-cycling. Ice builds up on the evaporator coil, the outdoor unit hums but never kicks on, or a ductless head flashes an error code. Refrigerant leaks, clogged condensate drains, and thermostats that forget their settings round out the list. Our technicians handle all of them, starting with the exact part that failed.

Some failures can wait a day, and some can't. A weak capacitor just keeps the compressor from starting. A cracked heat exchanger, on the other hand, can leak combustion gases into your living space, and a blocked condensate drain can quietly ruin a ceiling before anyone notices. We come prepared to replace capacitors, contactors, fan motors, igniters, flame sensors, and control boards, seal ductwork that's leaking air into the attic, and recharge refrigerant once a leak has been repaired.

Fast HVAC Help When Your Dover Home Needs It

HVAC failures rarely come at a convenient time. They tend to hit on the hottest afternoon of summer and the coldest night of winter, exactly when your family depends on heating or cooling the most. Same-day and emergency service from Dover HVAC puts an experienced technician at your door quickly, with the parts and equipment to find the fault and fix it on the spot. If the system is past repair, we plan and install a correctly sized replacement without a long wait.

Fast service shouldn't mean cutting corners. Even on emergency calls, we price the job upfront, go after the underlying cause instead of patching the symptom, and take the time to explain in plain language. That approach has earned us a lot of repeat customers all over Dover.

We Fix the Cause, Not Just the Symptom

We focus on solving the real problem, not just the symptom you noticed. Dover HVAC tracks down the failed component, the airflow restrictions wearing on your equipment, and the installation shortcuts that cause early failures, so problems are far less likely to return. As a family-owned, experienced and professional company, we treat your home like our neighbors' homes, because that's exactly what you are.

Each job follows the same straightforward process. We inspect thoroughly, recommend honestly, complete the repair or installation professionally, and give you practical advice on upkeep. From the first call to the final walkthrough, we handle every detail. For year-round protection, ask about our maintenance plans.
