HVAC Company in Alpharetta, GA
Dalton Heating & Air handles heating and cooling work across Alpharetta, GA, from compressor replacements in Windward homes to furnace repairs in Crabapple. Most Alpharetta houses run their air conditioning hard from May through September, and furnaces shoulder real load from December through February. That’s a long operating season, which means systems here age faster than the national average. For an honest estimate on a repair or a replacement, call (361) 306-9515. The three services homeowners call us about most each have their own Alpharetta page, linked just below.
Why Alpharetta Homes Are Different
Alpharetta sits in the upper Piedmont, so we get genuine heat and humidity in the summer and nights that dip below freezing often enough to matter. That swing is the point: an AC-only setup or an undersized heat pump gets exposed twice a year. Home styles add another variable. Windward and the streets off Kimball Bridge Road include a lot of 1980s and 1990s construction with furnaces that were efficient for their decade but are now past reasonable service life. Newer sections around Avalon and the Halcyon side of town have tighter envelopes and two-stage equipment, but we still see condensation management issues in crawlspaces and attics. Alpharetta also has HOA-governed communities where equipment placement, noise, and screening rules affect how a heat pump or condenser gets installed. The city publishes clear mechanical permit requirements, and we pull or file what the job needs. What we find most often: blower motors that never got a second thought, capacitors that give out in late July, and heat pump reversing valves that choose the cold week in January to fail after years of quiet service.
Our Main Alpharetta Services
AC repair and furnace repair are the two calls we run most often. Heat pump installation is the bigger-ticket job homeowners plan for once they see repair costs stacking up on aging equipment.
AC Repair in Alpharetta
When an Alpharetta system stops cooling in August, it’s usually the capacitor, contactor, or a refrigerant leak on older R-22 lines. We diagnose before we quote, and the price is in writing before any work starts. In Alpharetta’s heavier humidity, we also check that the condensate line is actually draining: a clogged line can trip a safety switch and shut the system down even when the mechanicals are fine. Full details are on the AC Repair in Alpharetta page.

Heat Pump Installation in Alpharetta
A heat pump can carry both cooling and heating in Alpharetta, but sizing matters. Short cycling on a hot afternoon or a system that never satisfies in January usually means the existing unit was not matched to the home’s actual load. We run the load calculation, correct any duct or return problems we find, and install units built to hold up through the full swing of an Alpharetta year. Read what the job involves on the Heat Pump Installation in Alpharetta page.

Furnace Repair in Alpharetta
In Alpharetta, furnace failures cluster around January cold snaps. Ignitors, flame sensors, and induced-draft motors account for a large share of our no-heat calls. We test the sequence of operation before we touch anything, so the repair is the one that actually fixes the problem, not the one that gets the truck out the door. Specifics are on the Furnace Repair in Alpharetta page.

Pricing for HVAC Company in Alpharetta, GA
