Licensed & NATE-Certified
Top Rated AC Repair Service in Lawrenceville 30+ Years in Business
Same-day air conditioning repair from a licensed, NATE-certified team that's kept homes and businesses across Lawrenceville and Gwinnett County comfortable for over 30 years.
Lawrenceville is mixed — the historic homes around the downtown square need a different approach than the new builds near Sugarloaf Mills or the Collins Hill area. Conserve has serviced both for over 30 years: older systems where you're weighing repair vs. replace, and newer high-efficiency units that just need annual care. We'll tell you straight which one your house needs, what it'll cost, and when. Same-day service across Lawrenceville, including 30043, 30044, 30045, and 30046.

Frequently Asked Questions
Does Conserve offer free estimates?
Yes. Estimates on new system installations and replacements are always free, with no obligation and no pressure. Just call (770) 403-3739 or fill out the form above and we'll take care of the rest.
How fast can you come out?
In most cases we offer same-day or next-day appointments, 7 days a week. If your AC is completely out, tell us when you call and we'll prioritize your visit.
How much does a new HVAC system cost in Lawrenceville?
It depends on the size of your home and the efficiency level you choose — which is exactly why we do a proper load calculation instead of guessing. After a quick assessment, we give you a clear, written price with no hidden fees, so you can decide with confidence.
How often should I service my AC and furnace?
We recommend a tune-up twice a year — your air conditioner in spring and your furnace in fall. Regular maintenance prevents most breakdowns, lowers your energy bills, and meaningfully extends the life of your equipment.
Are you licensed and insured?
Absolutely. Conserve holds Georgia Type 2 Conditioned Air Contractor License #CN210894 and is fully insured. Our technicians are NATE-certified and EPA-certified, so your home and your system are always in qualified hands.
Do you service commercial properties?
Yes. Alongside residential homes, we install and service commercial systems — rooftop units, chilled water systems, makeup and exhaust air, and VRF — for businesses throughout Gwinnett County.
