HVAC Company in Union City, GA
Union City sits in south Fulton County where the summer heat settles in by late May and doesn’t leave until October. Homes here run their air conditioning hard for five straight months, and the strain shows up as failed capacitors, tired compressors, and heat pumps that can’t hold a charge. Dalton Heating & Air handles AC repair, heat pump installation, and furnace repair throughout Union City with written pricing before any work starts and a full-year guarantee on every repair. Call (361) 306-9515 when you need a technician who shows up inside the window.
Why Union City Homes Are Different
Union City’s housing stock runs from 1970s ranch homes in the Shannon Villas area to newer construction along Highway 29 and the districts near Ronald Reagan Parkway. Those older homes often still run on original ductwork sized for a different era, while the newer builds pack tighter cabinets and attics that make equipment access a real constraint during a repair call. A furnace swap or heat pump replacement in a tight attic off Camp Creek takes longer and costs more than the same job in an unfinished basement, and that’s just the reality of the work here.
The red clay soil in this part of Fulton County shifts with rain and drought, which means condenser pads sink over time. A unit that sits out of level runs harder, builds up vibration, and shortens the life of the compressor. We check level, airflow, and condensate drainage on every service call because Union City’s particular mix of humidity and clay soil makes those three things fail before anything else does. Add in the occasional HOA requirement in the newer subdivisions about where outdoor units can sit, and the job becomes more about logistics than parts.
Our Main Union City Services
Most Union City homeowners reach out for one of three things: an air conditioner that stopped cooling, a heat pump that needs replacing, or a furnace that won’t fire in January. Each service has its own dedicated page with pricing, timelines, and what to expect.
AC Repair in Union City
When a Union City AC quits in August, the failure is usually a capacitor, a refrigerant leak, or a contactor that burned out from running nonstop since May. We diagnose the problem, put the repair price in writing before touching a tool, and carry the common parts for AC Repair in Union City on the truck so most jobs finish in a single visit. No overtime charge for emergency calls, and every repair carries the written one-year guarantee.

Heat Pump Installation in Union City
Union City homes that rely on heat pumps get year-round duty out of one system, which makes proper sizing and installation load calculations matter more than the brand name on the box. We size the unit to the home’s actual square footage, duct capacity, and insulation before quoting a fixed price for Heat Pump Installation in Union City. You’ll get a written install date, not a vague window, and the rebate paperwork handled as part of the job.

Furnace Repair in Union City
Union City’s cold snaps hit fast, and a furnace that won’t light in a 30-degree week is an urgent job. Our technicians check gas pressure, igniter condition, the flame sensor, and the limit switch, then hand you a written price before any repair begins. The Furnace Repair in Union City page covers the cost breakdown and what we see most often in this part of Fulton County. If a furnace repair fails within the guarantee period, the second visit is free.

What pushes a Union City repair toward the upper end is access. A furnace in a tight attic off Highway 29 or an AC condenser packed into a small backyard with clay-settled ground takes extra time to work around. Whatever the number, it gets written down before work starts, and that figure does not change at the door.
