Redline

We have used Redline for repairs maintenance and installation. They have been awesome to work with. On time, professional, honest and reasonably priced. Even during the hottest time of year! I would highly recommend them. All of the tech we have worked with are great, but Cory is even a knotch above excellent!

After 2 weeks sweltering in the 90°+ days in Denver…

Redline was the 3rd company I called to bid out a furnace repair (central air). Derek was amazing. Not only did he discover what was actually wrong with my unit, in which TWO other businesses misdiagnosed, he got it up and running within an hour or so. Derek was also very informative letting us know what type of maintenance and frequency we should be doing ourselves.
Redline will be my first call moving forward for all my HVAC needs.

P.S. The office staff was so friendly and helpful when I called to scheduled and that is always super appreciative when dealing with home repairs!

Connor came to look at our 20 year old furnace that was not working. He found a simple maintenace item that was overlooked by other companies. It was a quick fix and it was working perfectly again. He is honest, compotent and has great communication skills.

Derek has been out to service our water heater a few times. He is always on time, professional, and courteous, and takes time to explain everything to me. He’s always gotten it back up and running, but it was an old water heater and the day came when she had heated her last shower. He was out today and installed a new one for us. He had it installed, and ready to go quickly and efficiently. I also would like to add that Alicia, who I spoke to when calling them, is a pleasure. I appreciate everyone who has helped me at Redline. I would definitely recommend them to anyone who needs this type of service, hands down.

Everyone I have worked with on the Redline team has been excellent! Derek McKnight and Jason were both so professional, knowledgeable, and helpful. They were able to push through a very quick repair for me and work with the manufacturer to get it covered under warranty. I would recommend their service to anyone.

We've been using Redline for a few years. Great, local company. Derek is the best. He is always able to troubleshoot our very complicated old building, gives us helpful tips to keep our units in good condition between visits, and is always professional and friendly. The gals in the office are great too! Would highly recommend.

We just had a great experience with Redline. They could have really put one on us, since we don't know anything about hvac stuff. But Derrick was thorough and figured out I was just an air supply issue. Super friendly, and knowledgeable definitely going to save their number for future issues!

I got several quotes and did extensive research before selecting an installer for a new heat pump and furnace. Redline was right in line with other companies and the installer, Derek, was very knowledgeable and helped me make some decisions. They arrived on time for both the estimate and the work, did a good job, respected my home and were friendly and helpful. I would recommend Redline and Derek!

We have used Redline on numerous occasions, they have consistently been very professional and helpful. Always courteous and accommodating. They work diligently to problem solve the issue and resolve the problem. Would highly recommend them. Derek, in particular, has been awesome and we have really appreciated the consistency in having Derek out, as he has gotten to know our HVAC/AC system and is able to trouble shoot quicker knowing the system.

Derek did a great job servicing our malfunctioning hot water heater. He was on time for our appointment, professional, and provided a thorough explanation of the work needed and cost. He completed the repairs in a timely manner and I would definitely recommend Redline and Derek..
