They had good advice on choosing the brand and size of our unit, and since then I have had to call them twice in the middle of the hottest part of summer for a/c issues and they were there the very day I called both times, and had us right back up and cooled off. Both issues were warrantied as well. Great Folks!

Strangely, the side of the house farthest from the AC unit was the coldest, while the bedrooms never seemed to cool down properly. Initially, they thought some plumbing underneath the house might be restricting the cold-air returns and recommended that I have that addressed first. I had the plumbing moved to improve the airflow, but unfortunately, that did not solve the problem. The MainStream team came back and continued troubleshooting the system. They carefully checked the ductwork until they discovered a damper that was restricting airflow to the bedrooms. Once they opened the damper, the difference was immediate. The system is now distributing air properly, and the temperature throughout my house is more consistent than it has been in years. What impressed me most was that they didn't simply give up when the first possible solution didn't fix the problem. They came back, continued investigating, found the actual cause, and corrected it. I am extremely pleased with the service I received from MainStream Heating and Cooling and would definitely recommend them to anyone needing HVAC service. Thank you to the entire MainStream team for a job well done!

Cut pipe from bathtub and did not connect to anything, water ran all under house. Used old pipe with no glue, shoved small pipes into larger ones and covered with thin dirt cover. Left some old pipes wrapped with silver tape in yard, I guess this was the ones he brought and didn't use and left two piles of dirt after barely covering the old pipe he used. the pipe under the house left hanging had a towel around it, I guess that was his "pipe hanger". He never arrived during the day but always had an excuse for either no show or arriving at 4:30-5:00 p.m. saying his truck broke down or he had no babysitter. After arriving late, one day he left around 7 p.m and the next night he left around 2:00 a.m. But he went missing for several hours and left without saying he was leaving or would be returning. The next day he said he was sorry he had a "breakdown". He showed up that Friday afternoon to "complete" the job. He stayed in the yard a little over an hour or so, collected his money and left. The next day there was problems with a feeling of dampness in the house, a man came to inspect and found water all under the house from the bathtub that was not connected to anything. Further inspection found the "field line" to be old pvc of varying sizes, smsll pipes shoved into bigger pipes and not an ounce of glue. I have pictures of the mess that had to be completely redone. My husband is a 76 year old stroke victim and I have a musculoskeletal disease, he counted on us being unable to check his work. If he ripped us off, he will rip off anyone. He is a big talker and brags about his "work ethic" and how he is not trying to get rich off anybody and all the while he is ripping off! He shouldn't be allowed to touch any one's plumbing! His guarantee, like his estimate for "new pipe from Home Depot", is as useless as his work and word. Use this man at your own risk!!!

If you have not had a new HVAC system installed in your home, you won't believe how expensive the system can be, it's mind boggling, literally. I received pricing up to $18,000.00 for a simple 3 ton HVAC system. These folks are total professionals and I don't hesitate to let everyone know, without knowing what other HVAC people quoted me, they were not only competitive, they beat every other HVAC contractor hands down, not by hundreds, but thousands of dollars, so let me save you lots and lots of leg work and hours of telephone calls, Southern AIR Solutions has the correct Rheem system for you and you WILL NOT be taken advantage of, as so many in Bowling Green were willing to do, as evidenced by their system pricing.
