Coweta County gets furnace repair, AC repair and ductwork service from our office in Newnan, the county seat. Housing runs from antebellum homes in Newnan's historic districts to newer owner-occupied houses across the county, so a repair often starts with how air reaches the rooms. Long hot seasons and heavy spring pollen shape the rest of the work.
Home base in the City of Homes
Our office is in Newnan, the Coweta County seat. Newnan calls itself the City of Homes for its antebellum houses and has six historic districts on the National Register. Houses that old were built for fireplaces and open windows, so any central system in them was added later, with ducts routed through crawl spaces, closets and attics wherever they would fit.
That history shows up in service calls. Rooms at the end of long runs stay warm in July, returns are often too small, and a furnace on restricted ducts can trip its high limit. We measure static pressure and look at the duct route before recommending equipment.
A county where most people own their system
Coweta County had 146,158 residents in 2020, and about 73 percent of its occupied homes are owner-occupied. When you own the equipment, the repair or replace decision is yours, so we describe exactly what the fix involves and explain how much life the system realistically has left.
The county line also runs through Palmetto, which was incorporated in 1854 and lies mostly in Fulton County with a section in Coweta. Palmetto homes on either side get the same work.
The 2026 summer and the spring before it
By mid-September 2026, Atlanta had already logged 71 days at 90F or above, nearly double the usual count of about 38, and the first arrived in April, roughly six weeks early. A season that long wears out capacitors, contactors and condenser fan motors that might have lasted another year in a normal summer.
Spring brings a different load. Atlanta's pollen peak is driven mainly by oak, pine, sweetgum and sycamore, and on March 29, 2025 the local count hit 14,801 grains, far above the 1,500 level treated as extreme. Pollen mats the outdoor coil and loads filters fast. Our pollen-season filter guide covers how often to change them, and an AC tune-up with a coil cleaning restores airflow through a matted condenser.
Heating and cooling work that fits Coweta County
Furnace Repair
Furnaces in older Newnan houses often trip high limits because ducts added later restrict airflow.
Ductwork Replacement
Antebellum and early homes in Newnan's historic districts often need a duct layout rethought, not just patched.
AC Repair
A summer with 71 days at 90F by mid-September wore out parts that would normally last longer.
AC Tune-Up & Maintenance
Oak and pine pollen mats Coweta condenser coils every spring and cuts cooling capacity.
Whole-Home Air Filtration
Media filter cabinets hold more pollen than a thin filter during peak counts.
Furnace Replacement
With most Coweta homes owner-occupied, the long-term efficiency of a new furnace is the owner's to weigh.
Coweta County heating and air questions
Usually, with planning. Ducts can run through attics, crawl spaces and closets, and small-duct or ductless systems avoid cutting into plaster and trim. In Newnan's National Register districts we plan routes that leave the original features alone where we can.
The season was unusually long. Atlanta had 71 days at 90F or hotter by mid-September 2026, almost twice the usual count, and the first came in April. Capacitors and contactors wear with run hours, so a longer season brought failures forward.
Oak, pine, sweetgum and sycamore pollen coat the outdoor coil and clog filters. The coil then sheds heat poorly, head pressure rises and the system cools less while using more power. Rinsing the coil and changing filters during peak weeks keeps capacity up.
That depends on the furnace's age, the repair and the heat exchanger's condition. A failed ignitor or flame sensor on a sound furnace is worth fixing. A cracked heat exchanger or repeated control failures usually point toward replacement, and we lay out both options.
Both. Palmetto lies mostly in Fulton County with a section in Coweta. For HVAC the line makes no practical difference; we work on homes on either side the same way.
