"We had ATC take a look at our HVAC system that was not running well. Another company came out and told us the entire installation was wrong and everything had to be replaced, including all ducting. The price was astronomical. They also said that some structural work needed to be done, such as cutting through drywall and the house, which was not included. When Kevin from ATC came out to look, he said the ducting and the heater were just fine. The condenser and coil were old and probably should be replaced but it wasn’t an emergency. He suggested installing a dual controller and an additional return to improve the airflow issue we were having. He also gave us a quote for three options of new condenser/coils, along with financing options. The price was a fraction of the other company and the financing allowed us to do everything now rather than later. John and Kevin came out to do the installation. THEY WERE PHENOMENAL! They arrived on time, were so pleasant to speak with, were exceptionally patient with all our questions, were extremely knowledgeable about HVAC and split systems, were neat and clean, and did an extremely professional job of installation. That included all the drywall work that was necessary! And the improvement we received was unbelievable! Every room in the house was immediately receiving excellent airflow! We really thought we were in trouble, but these guys made sure we got all the cooling/heating we needed throughout the house with as little cost to us as possible. I would highly recommend the company and would especially recommend John and Kevin. They also fixed a split unit that wasn’t working. They can do it all!! Love these guys!"

"Had them do 2 units on my property. The first one was great, the pre team is great, and the guys who actually do the work. After the 2nd one, where I chose the more expensive option to get a Mitsubishi Heat Pump, the unit would not turn the fan on some of the time. I told them, and wasted insane amounts of time. They kept saying things like 'I am trying to understand what doesn't work.' 'Pretty simple, you choose to run the fan to simply circulate the air and the icon goes, Nest thinks it is on, but does not go on.' Then they said they were going to have a Mitsubishi tech come out and for sure it would get resolved. Never happened. Just listened to a book on Benjamin Franklin and he and John Adams had to share a bed one time while traveling and Adams went to close the window and Franklin said this place will be a tomb if you do. That was what 250 years ago? and HVAC is their business? Guess I will have to take them to court. The office staff post job is a clown car of silly children. So if your job goes great, they will be a good choice. If you run into an issue you will wish you hired ANYONE else. You've been warned."

Choosing the right Heating and Air Conditioning Contractor is very important. Chances are you are going to make a substantial investment in your new HVAC system with which ever contractor you choose. There is nothing worse than investing a large amount of your hard earned money in a new system and winding up with a system that is noisy, inefficient, and does not perform properly. Or even worse, one that fails prematurely. Surprisingly enough most HVAC Contractors have no formal training. Untrained HVAC Contractors frequently do not size systems properly which could result in improper cooling, very high utility bills, and even systems that fail prematurely. Before you even consider a contractor make sure they are NATE Certified and Air Balance Certified. North American Technician Excellence is the Prestigious Certification of HVAC Competence. Using a NATE certified contractor is like using a surgeon that graduated Harvard Medical School with honors. Air Balance Certified contractors understand airflow which equates to efficiency and comfort in your home. To have a system designed properly a contractor has to understand air flow. At Southland we offer this high level of expertise. Yes, we are very good at what we do and there is no question about that. Our reviews and ratings prove that. Our installations are unparalleled with every system being designed specifically to the home. All options for a quality installation are included in every system we install. From basic systems, high efficiency systems, to specialized zoning we do it all. If you are searching for a knowledgeable contractor you have found one here. We offer extremely competitive pricing and expert design knowledge.

"Dave was very efficient and knowledgeable. He was able to supply my quote before he left. I look forward to working with Southland heating and air. Follow up: I made my decision and signed the contract. Best decision I could have made. They were thousands of dollars less for the exact same equipment than 3 other companies I got estimates from. When challenged none of the other companies could revise their estimate to even come close. Southland is a Mitsubishi diamond dealer so I got full Mitsubishi warranties plus 1 year from Southland of parts and service. The day the installers arrived, on time, it was raining. Jamie and Ricardo used the utmost care to protect my home. They covered the floors, moved and covered the furniture and made sure before they left that I fully understood how to use the remote and operate the equipment. I have attached a photo so you can see for yourself the way they carted for my home. The equipment works perfectly. I would hire this company again in a heart"

"Easy communication. I needed a bathroom exhaust fan installed where there is no attic access. The project included wiring and ductwork to the exterior as well as drywall removal and repair, and then finishing everything beautifully. The two-man team of Vasquez did as instructed and also fixed some old shoddy work that was in the way of the new duct and wiring. They used good materials and did good work at a good price. They were also very respectful of my home, keeping the mess contained and cleaning up after. I would hire again."
