Customers Say

“Thank you Aaron Hart! I waited 5 years to call an HVAC because I was afraid of the cost. I checked on Next Door for reliable HVAC companies and the comments were accurate and so was Yelp! These guys are fair and honest. Appreciate you so much!”

Jessica K.

“These guys are the best. They show up when they say they’re going to be there. They are competitive but reasonable and aren’t there to take advantage of you in any way. Honesty is extremely important when looking for specialty services in Las Vegas and these guys are top notch.”

Stephen P.

“Family owned business, who’s very reliable and gave the best customer service! They replaced my coil system, and even cleaned up after the service. Best rates in town. Not to mention they also followed up after the installation! I highly recommend this trustworthy company.”

We appreciated Jessica’s quick response to our thermostat not working, since we were without A/C. Aaron installed our new thermostat which I know will save us money. It is so easy now to go onto our phones to increase/decrease the temperature, we love it!I know this feature of easily being able to adjust the temperature will save us money, I already see it on the light bill!

Had a problem with my A/C, Shawn came over the next day, checked everything out, had to fix my damper, got it done quickly and I was charged less than $100. I was happy with his attitude and friendliness and will be using them in the future.

Vegas Knight & Day were our go to firm after a good experience previously. On this visit they were able to correct an issue with our unit not heating where two other firms sent out by AHS could not resolve. Thank you for getting our units back in order. We will definitely be reaching out with any other needs.

We had our furnaces serviced by Aaron. He was punctual, professional, and was incredibly nice and well mannered. We have been in the market for a servicing company and so happy we went with them instead of some other competitors. Jessica who helped me schedule the appointment when I called the number listed was extremely polite, patient and helpful. Highly recommend this company, all the team members I've encountered throughout this entire process was a gem and rare to find these days. Thank you Vegas Knight and Day!

Thank you Aaron Hart for being fair and honest! Next Door and Yelp were right about this company. They are dependable and do not try to price gouge the customer. They answer their phones, they give you a window of time they will arrive, and text you when they are on their way. Aaron assessed everything and gave me my options and how much each would cost. Aaron also shared what I need to do in the future to care for HVAC. He was done assessing and fixing in under an hour! Appreciate you guys so much! I have heat and a/c again downstairs too!

I can’t recommend this company enough. The service was top notch from start to finish. Jessica was super helpful on the phone and got us an appointment quickly. Our tech, Aaron, was super friendly and professional. He quickly found the problem after another company told us our only option was to replace our entire HVAC unit. He fixed it for us same day and it’s working perfectly. We’ll be calling Vegas Knight and Day from now on!
