Where do most HVAC installations go wrong? Most often before the first wrench turns, when someone matches the new tonnage to the old nameplate and skips the math. At Dover HVAC, the math comes first. We build a load calculation for your Dover, NH home from its square footage, insulation levels, windows, orientation, and air leakage, because sizing errors in either direction cost comfort and money every day the system runs. From there the job becomes three connected pieces of work: equipment matched to the load, ductwork able to deliver what that equipment produces, and a commissioning process that proves the result on the meter instead of on paper.
Most of our service calls are for AC Repair and Furnace Repair. Start there if your system isn't running right.
Signs You Need HVAC Installation in Dover
Catching these issues early helps you avoid costly problems. Watch for these telltale signs:
- Utility bills rising each season as comfort slips
- Major components failing on both sides: compressor one year, exchanger the next
- Your furnace and AC have both passed twelve to fifteen years of service
- A system noisy enough that you have to talk over it
- The system still runs phased-out R-22 refrigerant
- Air that feels cool but damp in summer, a classic oversizing symptom
- You are renovating or adding space and the old system cannot carry it
- Hot or cold rooms that no vent adjustment can fix
