Alpharetta’s HVAC work splits into two very different jobs: maintaining large, multi-zone systems in homes built after 1990, and working around original ductwork in older houses near downtown where the crawlspaces and attics were never designed for today’s humidity levels. Dalton Heating & Air handles both. We’re a Garrison Partners company, we put every price in writing before work starts, and every repair carries a full-year written guarantee. If you need an HVAC company in Alpharetta that shows up inside the window and stands behind the work, call (229) 537-2086.
Why Alpharetta Homes Are Different
Alpharetta’s growth from a small town to a sprawling suburb happened fast, and the housing stock shows it. Homes in Windward and Kimball Bridge regularly run 3,000 square feet or more, which means two separate systems, two thermostats, and zone dampers that have to work together. When one zone won’t cool, the culprit is often a failed damper motor in the bypass duct rather than the AC unit itself. Older sections like Downtown Alpharetta tell a different story: 1960s-1980s homes with original ductwork in attics and crawlspaces, where leaks and poor insulation quietly drive up cooling costs all summer.
The climate doesn’t let any of it slide. Alpharetta’s humid subtropical weather means air conditioning runs hard from May through September. Spring pollen clogs condensate drains. High humidity forces systems to work longer just to pull moisture out of the air. Winters are usually mild, but freezing nights do arrive, and furnaces that haven’t been touched since spring have a way of failing on the first cold morning. New or old, every Alpharetta home has something specific going on, and the fix usually starts with knowing which kind of house you’re standing in.
Styles & brands we work with
Our Main Alpharetta Services
The three calls we get most in Alpharetta are AC repair, heat pump installation, and furnace repair. Each has its own page with pricing, timelines, and what to expect.
AC Repair in Alpharetta
Alpharetta summers push AC systems to their limits. We see refrigerant leaks in older units, failed capacitors on 10-plus-year-old systems, and clogged drain lines that trip float switches and shut everything down. On the larger multi-zone homes, a common call is one floor blowing warm while the other stays cold, which usually points to a damper or airflow issue rather than the compressor. AC Repair in Alpharetta covers our diagnostic process, what common fixes cost, and how quickly we can get a technician out.
Heat Pump Installation in Alpharetta
Heat pumps work well in Alpharetta’s climate, handling both summer cooling and the mild winter heating load. When we install one, we’re sizing it to the home’s actual square footage and duct layout, not just swapping in the same tonnage that was there before. That matters in older Alpharetta homes where duct leaks or undersized returns have been fighting the old system for years. Heat Pump Installation in Alpharetta walks through load calculation, brand options, and what a full installation includes.
Furnace Repair in Alpharetta
Furnace problems in Alpharetta usually surface on the first cold snap, when the system has been idle for months. Igniters, flame sensors, and blower motors are the frequent offenders. In older homes near downtown, we also find cracked heat exchangers on furnaces that are near the end of their service life, and that’s a safety issue that needs prompt attention. Furnace Repair in Alpharetta explains what each symptom typically costs to fix and when replacement starts to make more sense.
