Signs You Need AC Repair

Air conditioning problems often start with small changes before turning into full system failures.

  • Warm air coming through vents
  • Weak or uneven airflow
  • System not turning on or shutting off unexpectedly
  • Water leaks or moisture around the unit
  • Unusual noises during operation

These issues indicate your system is not operating correctly and should be inspected.

Quick Checks Before Scheduling Service

A few simple checks can rule out minor issues:

  • Thermostat settings are set to cooling mode
  • The circuit breaker has not tripped
  • The air filter is not clogged or blocked

If the problem continues after these checks, professional repair is needed.

What Happens During AC Repair

A proper repair starts with identifying the exact cause of the issue, not guessing.

  • Inspect system components and overall operation
  • Test electrical connections and controls
  • Check refrigerant levels and cooling performance
  • Evaluate airflow and system pressure
  • Identify failed or worn components
  • Complete repairs using compatible parts
  • Test system to confirm proper cooling and operation

This process ensures the issue is resolved and the system runs correctly.

AC Repair Services

Air conditioning systems include multiple components that must work together. Repairs are based on the specific failure within the system.

Component Repairs

Issues with motors, capacitors, or electrical controls can prevent the system from running or cause inconsistent operation.

Refrigerant and Cooling Issues

Low refrigerant levels or leaks can reduce cooling performance and strain the system.

Airflow and Performance Problems

Blocked airflow, damaged components, or system imbalances can affect how air moves through your home.

We repair all major air conditioning brands and system types.

Phil was outstanding! He diagnosed a problem that several other techs from a different company couldn’t figure out. He was so friendly and took the time to explain everything clearly. Highly recommend Phil from Southport!

Great experience on updating our HVAC systems to heat pumps/backup furnaces.
Ryan, Oliver, Andrew and Jacob (all installers for Southport) are wonderful, competent, and delightful young folks, who gave great service doing the physical upgrade of 2 older heat/ac systems.

I highly recommend Southport for your future HVAC upgrades. All the folks from the person doing the bids (Adam) to Manager (Jackson) to all the installers, are first class, professional and proud of where they work and what they do.

Losing AC in hot weather is never fun, but Southport made the whole process as painless as possible. They were quick to respond, easy to work with, and got everything moving fast when we really needed it.

From the initial quote to the installation of our new AC and furnace, everyone was friendly, knowledgeable, and professional. The communication was great, the work was done efficiently, and everything went smoothly.

We're extremely happy with the result and wouldn't hesitate to recommend them to anyone looking for HVAC work.

Got a furnace replacement and a/c unit install. Both work great. The hvac techs worked very hard but they were not so thrilled to be doing a full install on a friday. they made it clear by complaining within earshot for the whole 7 hours. So maybe consider not scheduling with them on a Friday and it may be a better experience for you. 5 stars

I purchased my furnace from Southport and needed service when my AC went out during a storm. Andrew,my service tech was fantastic! He explained everything, got the parts the same day, and had me up and running in no time at all! At his recommendation, I also purchased a surge protector and maintenance agreement so I can rest easier during storms. Thank you Andrew!!

I was referred to Southport by a co-worker. Their staff is super friendly and informed. The sales manager Nate was reasonable to work with. You can probably save a few hundred bucks going with a smaller company with less overhead, but I think the peace of mind that comes along while working with an established company like Southport, is much more important. They got me booked for an instilation appointment within two days of signing a contract! Their technicians were polite and did the best they could at keeping my carpeted basement clear of mud, considering the first few hours they were there was during a rainstorm. Whatever mess they made they cleaned up. The installation took longer then expected (about 10 hours) but there was a lot of work to be done, and the technician thanked me for my patience. He said it's nice to be able to take their time and make sure everything is installed perfectly! All and all, I had a positive experience, and highly recommend using Southport. Friendly and fast service at fair price!

Justan and Luke did a great job on replacing our utility laundry sink and replacing our compression water valves to 1/4 turn valves. They involved us in every step of the process to make sure they were doing it exactly as we wanted it done. Friendly, professional and skilled at what they do!
