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!

We had our air conditioner replaced by All Temperatures Controlled INC in the spring. The Service Provider was knowledgeable in helping with our selection. We also had our air ducts replaced in order for more efficient air flow. Everyone at All Temperatures Controlled was very respectful and helpful. We are pleased with the quality of the air conditioner installation and operation.

I paid this company to come back in to perform an inspection and they found the real problem and replaced the part and installed a new gas line with an automatic shut off valve.  They also made sure that our unit was up to code.  I ended up paying $330 to get it fixed rather than taking another companies word for it and replacing the system. I would highly recommend ATC.  I called and thanked them after the work was done.
