AC Repair
Our technicians provide fast, dependable AC repairs to restore cooling during Louisiana's extreme heat. We diagnose issues like warm air output, strange noises, and electrical problems, using specialized tools and manufacturer-approved parts. With 24/7 emergency availability, we prioritize urgent cases to minimize discomfort while ensuring long-term system reliability through thorough diagnostics and repairs.
AC Replacement
We install energy-efficient AC systems designed for lasting performance and lower utility bills. Our experts assess home size, insulation, and climate needs to recommend optimal units from trusted brands. The process includes proper sizing calculations, old unit removal, and ductwork evaluation, ensuring seamless integration with existing infrastructure while maximizing energy savings and indoor comfort.
AC Maintenance
Annual maintenance plans extend system lifespan and prevent unexpected breakdowns. Our comprehensive inspections include coil cleaning, refrigerant checks, electrical connection tightening, and airflow optimization. Regular maintenance improves energy efficiency by up to 15%, reduces repair frequency, and maintains manufacturer warranty validity through documented service history.
Emergency AC Repair
Available round-the-clock for critical cooling failures, our emergency team responds promptly to situations like complete system shutdowns or refrigerant leaks. Equipped with diagnostic tools and replacement parts, technicians resolve urgent issues during extreme weather conditions. This service includes priority dispatching and after-hours support to restore comfort as quickly as possible.
Ductless Mini Splits
We install and service ductless mini-split systems for homes without traditional ductwork. These zoned solutions allow independent temperature control in different rooms while improving energy efficiency. Our technicians handle multi-zone configurations, wall-mounted unit placement, and smart thermostat integration, providing quiet operation and improved indoor air quality through advanced filtration systems.

We moved into a new home that had an existing older Trane unit with some minor issues. GHAC came in and fixed an outdoor overflow leak that the previous owner said existed for years, cleaned up some things and set us up on a maintenance plan so we could receive the repair at a discount and get the most life out of the unit in the years to come. Arrived on time, courteous and answered all of our questions.

Honest worker, gave me the details of what he had to check and do. Found a possible freon leak. Used a dye in the new freon and returned 4 days later to check on the possible leak. It was discovered in a coil installed in 2013, but the warranty was up in 2018. Will return to replace the coil as soon as possible.

We have used this company for years and they do a great job. Some of the technicians are better than others, but they are all excellent. Most recently Jeff came to solve a problem with our air-conditioning and he was like Sherlock Holmes looking at dust samples in vents to figure out the problem and solve it. Brilliant!

GHAC installed my unit (replacement) originally and I have had a service contract with them for several years (thankfully they have a very professional and efficient office staff to ensue I schedule my visits timely!). My technician, Ron, is always professional, pleasant and genuinely concerned that our system runs at maximum capacity for maintaining our comfort. He always calls and arrives when scheduled, is very helpful when explaining what needs to be done and why, and always proactive to try and avoid possible "emergency" issues down the road that would keep us without our cooling system due
