AfterHVAC Company in Kennesaw, GA
Dalton Heating & Air handles HVAC work across Kennesaw, GA with a straightforward approach: the price is in writing before any work starts, and every repair carries a full-year written guarantee. Kennesaw’s mix of 1980s-era subdivisions, newer construction along Cobb Parkway, and older ranch homes near downtown means we see a wide range of equipment ages and duct layouts. That variety changes how we diagnose problems, size heat pumps, and route emergency calls. If your system is down, call (361) 306-9515 and a real person answers, day or night.
Why Kennesaw Homes Are Different
Kennesaw sits on a ridge line where summer humidity from the Chattahoochee drainage settles in hard, and the equipment load is real: an AC system that runs fine in drier parts of metro Atlanta works measurably harder here. We routinely find condensate drain lines backing up in slab-foundation homes in Legacy Park and Ridenour because Georgia clay holds moisture against the slab, and the combination of short crawl spaces and long horizontal duct runs in neighborhoods around Butler Creek means a lot of duct-sealing work that newer developments never need.
Housing stock matters too. The older sections off Main Street and Cherokee Street still have systems sized for the building codes of their era, so a straight equipment swap without a load calculation often leaves upstairs rooms hot in August. Meanwhile, homes in Summerhour and the townhome clusters near Swift-Cantrell Park run newer units, but builder-grade installs can still have airflow problems in second-story runs. Every Kennesaw job has to account for specific neighborhood conditions, and that is a big part of why we send technicians who have worked this area, not a rotating cast of subs.
Our Main Kennesaw Services
Most calls from Kennesaw homeowners fall into one of three buckets: an AC that has quit or lost cooling, a furnace that won’t heat in January, or a full heat pump install. Each has its own page with pricing, what to expect, and how we handle the job. Here is what you should know about each in Kennesaw specifically.
AC Repair in Kennesaw
Kennesaw’s humidity means air conditioners here fail differently than they do in drier climates. The most common calls we run are for frozen evaporator coils, failed run capacitors, clogged condensate lines, and low refrigerant. A AC Repair in Kennesaw call starts with a written diagnosis and a written price before we touch the unit. Most repairs run $150 – $650 depending on the part, and the work is guaranteed in writing for a full year. If the repair does not hold, we return at no charge, no questions asked.
Heat Pump Installation in Kennesaw
Heat pumps are a strong fit for Kennesaw’s moderate winters, and we install a lot of them as replacements for older gas furnaces and straight-cool ACs. A Heat Pump Installation in Kennesaw includes a Manual J load calculation, a written fixed price, and a set install date before we order equipment. Sizing matters more in Kennesaw than most homeowners realize, because undersized units cannot keep up with July humidity loads and oversized units short-cycle, which leaves the house clammy. Install pricing runs $3,500 – $7,500 depending on capacity and ductwork.
Furnace Repair in Kennesaw
Kennesaw winter nights dip into the twenties enough that a furnace failure is a genuine emergency. Common failures we fix are failed igniters, gas valve problems, bad flame sensors, and blower motor failures. Furnace Repair in Kennesaw runs $150 – $700 for most jobs, with the higher end covering blower motors or control boards. Like every Dalton repair, the work is covered by a written full-year guarantee, and we service furnaces from Rheem, Goodman, York, and Daikin, among others. If it’s not safe to run, we tell you plainly and show you why.

Pricing for HVAC Company in Kennesaw, GA
| Service | Typical range in Kennesaw |
|---|---|
| AC repair (capacitor, contactor, common parts) | $150 – $650 |
| Furnace repair (igniter, flame sensor, gas valve) | $150 – $700 |
| Full AC installation | $3,500 – $7,500 |
| Heat pump installation | $3,500 – $7,500 |
| Seasonal tune-up | $80 – $200 |
What pushes a Kennesaw job toward the top of these ranges is usually access: a furnace in a tight attic off Barrett Parkway takes longer than a ground-level utility closet, and older homes with original ductwork sometimes need sealing or replacement work before a new system will perform. Regardless of the number, the price is in writing before we start, and it does not change at the door.
