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 Durham HVAC, the math comes first. We build a load calculation for your Durham, NC 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 with real readings instead of on paper.
Our two most requested repairs are AC Repair and Furnace Repair. Start there if your system isn't running right.
Warning Signs for HVAC Installation
Catching these issues early helps you avoid costly problems. Keep an eye out for the following clues:
- An older system charged with phased-out R-22
- Paying more every month for a house that feels worse
- Rooms that never reach temperature no matter how the vents are adjusted
- An addition or renovation the existing system was never sized for
- Rattling, humming, or roaring loud enough to interrupt conversation
- A compressor failure one year and a heat exchanger problem the next
- Your heating and cooling equipment is past the twelve-to-fifteen-year mark
- Short, frequent cooling cycles that leave the house clammy
Act Before It Gets Worse
A failing capacitor, clogged condensate drain, or dirty flame sensor rarely fixes itself and usually gets more expensive to address the longer it runs. Don't wait, call (984) 213-5892 and we'll take a look right away.
