We'd recently purchased a new house in Little Elm, Tex. and needed the HVAC system serviced and the A/C and heating vents repaired prior to our move-in.

Richard Neely of System Control Air Conditioning & Heating was prompt, professional, and knowledgeable. He did a thorough job of servicing our HVAC system and vents, and his pricing was very reasonable.

We will definitely use him again and recommend him without reservation. I've included his contact information below for your reference and use!

Moving into an older home, I was skeptical of how the prior owners had taken care of the house, and that included the HVAC units. This is my 2nd year having System Control out to do yearly maintenance. After checking and replacing the filter, they were able to run some quick tests on the units and gave me assurance that the equipment is still running as expected and that there aren't any issues needing to be addressed. They even gave me some tips on how to help maintain the units throughout the summer months to extend their lifespan. Thanks Richard and team for helping take care of our much

Horrible. We used this company because our landlord said he’s been working with them for 20 years. When the a/c repair guy got there he looked around and said everything is fine and charged $225. We told him he didn’t do anything. Why should we pay him? He said the money was for him to go out and “check” what’s going on. He didn’t even diagnosed anything . He just walked around and stuck a machine to get a reading and he said the “a/c was fine”. My parents doesn’t know English so they paid him. I got to the shop after a couple of hours and the a/c still did not work. We called

I live in Forney and I called into System Control INC just after 5:00pm when they had closed for the day and left a message, by 6:00pm I had received a call and set an appointment for 11:00am the next day. At 11:15am I get a call from Oscar the HVAC engineer who told me that he is just around the corner and will be with me shortly, 5 minutes later he arrived and immediately listened to what I had to say, which is not always normal nowadays. He checked out both of our HVAC units and furnaces and found the issues. He serviced both units and cleaned them, checked pressures etc and kept me informed

I’ve used System Control for quite a number of years and I’ve always been impressed by their honesty and hard work. They’re located a little outside of Dallas but they do work in Collin County as they’ve done work at my house in Plano.
I try to be very thorough in researching companies I use. I’ve gone through quite a few A/C companies and there are other decent ones (at least based on my experience) in the area, but System Control is the best of all that I’ve used. I’ve dealt with Richard and Rickey and they are always very thorough, courteous and professionally. Most importantly
