They called ahead of time to let us know they were coming. They were right on time. They checked out our heater. We had just bought the house and couldn’t get the pilot light lit. The tech determined that there was air in the line, so he bled the line and got the pilot light lit. He checked out the heater and told us the heater was fine and didn’t need any more work.

Living in Texas we learn to appreciate our Air conditioners! I was ready to freak out yesterday when my unit stopped working and I am expecting some family over this weekend for the holidays! I started searching for a reputable air conditioning company in the metroplex. Couple of my friends at work referred me to MB Kiser and I decided to give them a try! I have called their customer service and lady on the phone was very knowledgeable and willing to help, which was a big plus for me.

We have a service contract with them so they come every six months to prepare the furnace and air conditioner. We get a reduced rate for any repairs because of the contract and we never get charged for any overtime. My parents also use them. I would recommend them. They redid our whole system in our old house. We’ve used them for 45 years. One of the guys remembered coming to our family home when I was little.

They are great. Our downstairs unit went out. They were able to put in the model I wanted. It was a 5 ton horizontal system, and a difficult installation. They had the resources to get it done. They ran into some problems but they charged us what the original bid was. They were also able to fix the upstairs air conditioning. They are very professional and always respectful. They were able to troubleshoot as they went along. If there were any problems, they were able to fix them.

OVERALL EXPERIENCE WAS 100% POSITIVE.

I have now used MB Kiser for about 12 years. They have always been fast and honest. Recently, I had my AC go out at my office they fixed it fast with a $35 capacitor. The repair person I had out before Kiser tried to sell me an entire hvac system. Kiser also repaired one of my home units at 8pm on a hot evening fast and easy. Much to my amazement they did not even charge for emergency or afterhours. M.B. Kiser is wonderful to work with.

We had our second HVAC system installed by M.B. Kiser today. They are excellent. The installation team arrived at 8:30 and left at 6 with all the work complete, area cleaned up and a great Carrier Infinity system installed. We have two systems in our house. We had the same setup installed last year and it has been flawless. The prices are competitive and the installers and service people are professional, competent and excellent communicators. Highly recommend.

THIS COMPANY DOES BOTH COMMERCIAL AND RESIDENTIAL WORK. HAD A NEW SYSTEM PUT IN AT THE BARBER SHOP. WORKERS WERE VERY PROFESSIONAL AND THE WORK WAS DONE QUICKLY AND CORRECTLY. ALSO HAD THEM COME AND REPLACE A HEATING UNIT AT HOME. SAME GOOD SERVICE AND PRICE WAS COMPARABLE TO OTHER ESTIMATES THAT I GOT.

Rebecca J.

I have used MB Kiser three times now at two different properties. Kenny and John are the best techs I have come across. This is a company that really puts their customers first which probably explains why they have been around so long.

David W.

Quick response, my AC was out Friday all day and they came out first thing Saturday morning. Jordan answered all my questions, and verified the issue within first 10 minutes. I would highly recommend using them in the future.

Saj J.

Annual maintenance plan is pretty straightforward and a much better value than paying twice a year for the same service at twice the rate. Service manager came out after the first call didn’t fix it, and made sure the unit cooled. Awesome service and friendly people.

Daniel M.

Happy MB Kiser customer since 2014. Great company, very dependable and always on time. My A/C bit the dust on Monday, and they sent a tech to fix it right away. A broken A/C in Texas during summer time is as good as a death sentence lol. Luckily these guys are always around. Thank you the MB Kiser team and Jordan in particular. Big thanks to Kristen for expediting the part ordering.

Oleg M.

Thank you so much for your consideration. I truly appreciate your service to keep my aged system working.

Vincent F.

Well we used them twice and both times were happy with the price and work that was done.
