Customer service was good. The technician was courteous, fast and seemed to know what he was doing. I won’t know if it is truly fixed until later today and or the near future. If the AC works correctly then it is fixed. If it doesn’t, it isn’t. I’m not an AC technician, or I would have fixed it myself

My thermostat was not working appropriately, resulting in warm air blowing on a cool setting. I contacted Mainstream and they had a technician ready to come out the same day. They replaced my thermostat and my unit was cooling once again. Thank you very much for getting my unit working correctly again!

Service all around was excellent! I spoke with Mainstream Heating and Cooling on Monday morning about my issue and they worked me into their schedule the same day. Mainstream was awesome, the service repairmen were professional and personable. To my surprise, they replaced my 2 older WiFi thermostats that I purchased from them several years ago with 2 upgraded WiFi thermostats at no charge! Thank you very much Mainstream, the new thermostats are working great!

They gave the lowest estimates. When they were going to be very late unexpectedly, the owner himself called to apologize and came out in place of the technician. We had a set amount of money, so he got us a better unit at a lower price in order to get us a better unit rather than just the cheapest one.

They said the cooling air compressor was going bad and then the guy we normally used was back again and he went out and looked at it and they found the different problem and it's working fine as far as we can tell. It appears right now that they misdiagnosed it. We needed somebody right away and we have tried some other folks and they couldn't get to it for a day or so and Mainstream said that they would get it on that same day they couldn't give me a time but they didn't, come on that same day and they got it working again. And then two or three days later it went out again and so I called them and asked him to go back and find out. The first time it was blowing fuse and so I asked him will you go back and find out what causes the fuse to blow because it blew again. So, they went back and this time they said that the compressor was good. They had purchased $1500 or $5000 replaced the whole thing and a replace with a fuse got it working again. So, we have a little bit of time to figure out what to do in our regular fellow I had a lot of compliment in because we've been using them a long time. So, they got back and they took a look at it and they found the different problem and doesn't think that the compressor was going bad. And instead of $1500 it could flack a $40 apart. I would not use this provider again in the future.

Ms [removed member name], thank you for your feedback and I would appreciate more details. The reason for your complaint and "F" score seems unclear to me. We were called on July 23rd and arrived the same day, in the middle of summer when others could not. We diagnosed and replaced a bad 30 amp fuse and your unit was running properly when we left. You called us back on July 30th and we diagnosed the electrical winding in your compressor as soon to fail. We recommended you replace either the part or the unit. As a courtesy, we did not charge for this visit, despite them being separate mechanical problems. From our perspective, we delivered great fast service when other companies could not, diagnosed and fixed your initial problem with a same day speed for a low fee and then returned, free of charge, as a courtesy, and found that your old unit was wearing out and needed to be fixed. The compressor is the engine of your system and it wears out with use just like your car motor does. Thank you for additional feedback to us as to what you think we did wrong or what would have needed to earn us a passing grade. As always, thank you for using our company and feel me to contact me directly with any questions as well.

Ms [removed member name]: Thank you for using Mainstream and my apology for not communicating that Filters are the homeowners responsibility. When we do an annual service, we focus on the machine and making sure it is running at maximum efficiency. Our 21 point inspection helps makes sure you have the best operation possible. Filters should be changed frequently during the year. We have found it best if you use the arrival of your power bill as a trigger to check them and change as needed monthly.

Our first experience was great all around, from the sales to the ending inspection. Our second experience was not the best but ended on a good note. The salesman was horrible and never gave us a quote, even after several phone calls. After this the owner became involved and he was very responsive and took care of us completely. We had a few issues with the install crew and the superviser having miscommunication but again the owner took care of things and made everything right. Overall we are pleased and feel that njo one could beat Mainstream.
