Report
Every spring, before it gets hot outside, we have our AC inspected. Today was a routine visit by a tech to make sure everything was working properly. I spoke with Lisa in the office, and she was pleasant and helpful. Michael Boyle came out and spent about 1 1/2 hours at my home, checking out the compressor outside, and the blower on the furnace, and he was VERY thorough. He took the time to explain things to me, to show me readings on his equipment, to warn me of possible issues down the road.
There is no doubt in my mind that he knew what he was doing, and that he checked out EVERYTHING, and sincerely wanted to give me all the options needed in order for me to make some sound decisions going forward. He was very knowledgeable and answered all my questions. If you call them, ask for Michael! Great service from a great company!

I highly recommend southwest heating and cooling. I was impressed with the entire process beginning to end. I filled out an appointment request on their website and was contacted the next day to set up and appointment. A few days later the tech came out and told us we needed a total replacement of our furnace and AC unit. He could not have been nicer. He took the time to fully explain everything and all of our options.
Once we agreed, service was schedule within days. They contacted frequently with updates on arrivals and confirmations. The crew, lead by Jesus Gomez, was exactly on time(actually a few min early), were extremely friendly and informative, not to mention clean and detail oriented. Once the install was finished, he took the time to show me everything and explain how the new system works. The whole experience exceeded my expectations and I would highly recommend them.

Jesus Gomez did a terrific job of installing my new furnace and air conditioner. It was a big job and if not done right could shorten the life and affect the efficiency of the system. He did it right and took his time to explain everything to me. I would refer him to any of my friends or relatives. Services: Install AC, Heating system installation

Upgraded from a swamp cooler to AC, but had to replace our original 50 year old furnace. Decided to get a new hot water heater at the same time. So, kept Jesus and Rony busy the entire day. They were hard workers and a great team. From the time I called for an estimate, things moved quickly (our first meeting at home was on Friday and we scheduled the install for Tuesday). Not the least expensive quote, but everything moved smoothly and though it has only been a few hours we are happy with our decision.
