Customer Reviews

See what the community thinks about us!
  • I Highly Recommend Day & Night to everyone I know. They are a passionate Company that really cares about the Customer. They went beyond the services of making sure our a/c unit was repaired and properly working. Everyone was courteous and passionate about the problem. Chris and Jesus were very professional and honest about what was going on with my unit. They explained everything to me and gave me my options. The prices were very reasonable. I will definitely continue to be a customer. Thanks so much. I appreciate it more than you know. Great Job guys! — Toni N.

  • They did a great job fixing the AC. They really helped us out during a difficult situation. Highly recommend. — Lisa T.

  • Day and Night Air Conditioning have heart. A lot of heart. As we have old units, we've needed their help a lot in the last two years and they've worked super hard to accommodate us and get our air cooling again. This includes: calling at 8pm and having them here by 9pm; having them fit us in early morning before their previously scheduled jobs, etc. When you call them, you normally get a real person who listens, coordinates, and genuinely has compassion. And with the experience of their senior technicians, I feel like they can handle any kind of commercial or special situation (such as having a disused heat pump, etc.) Overall, I'm so glad I found them. I would genuinely have no problems giving them the keys to my house if I needed service while out of town. I think that says a lot. — Harry S.

  • Great company! Very responsive, very professional, called for service on our company's units and they came in, serviced them and have is a great value along with the Yelp credit. So impressed I signed up for their yearly maintenance program. — Jimmy P.

  • I had been dealing with really warm temperatures (83-86) inside my home for 10+ days. My landlord had two different companies come out, and two more who stood me up. Needless to say, I was beyond upset, and just wanted my AC fixed. My landlord left it up to me to find a company. Naturally, I went straight to Yelp! I called Day and Night at 7:57 on Friday night. Kim answered my call from the movie theater. I suggested they wait until Saturday morning, but she was happy to get someone out that same night. I really didn't expect much. But guess who showed up at 10:30!? Chris diagnoses the problem in no time. The problem couldn't be fixed immediately, but they were back out Saturday morning. They replaced the unit for less than it would've cost to fix. He came out a few hours later to make sure the temp was dropping properly. I've never been so happy with an AC company. These guys really know their stuff, and they care! They will be my go to guys from now on. Couldn't be more happy, as I type this, with a thermostat reading 72 degrees. — Tracy S.

  • I don't write many reviews, but when I have an exceptional experience with a company I almost feel compelled to do so. Our AC was running warm for several days and we were pretty miserable. We had another company come out and do an inspection. He first checked the freon level and said it looked ok, then looked at the furnace and said he suspected the coil was dirty and it would be $800 to clean it, and promptly tried to sell me a 13 seer system for more than 14 seer systems cost. I called Day and Night the next day and scheduled an inspection. The technician came out and the first thing he asked was if the freon level had been checked. I told him it had and that the previous company said it was ok. He stopped and went back to his truck to get his gauges because he wanted to make sure the other guy had done it correctly. Low and behold, he showed me on the gauge that my system was a few lbs. low on freon and gave me a very good price for R-22 (some companies are gouging because it's being phased out). He charged it and within the time we were talking outside, my house had gone down 2 degrees and I could tell the difference immediately that the air was cooler. We talked at length about dishonest companies and how people are sometimes scammed and got the sense that this is a very trustworthy company. Again, I don't write many reviews, but after talking to the technician and having my AC back in working order, I felt like I had to. If you're looking for an HVAC company that you can trust, I would give Day & Night a Call. — Chris T.

  • Day & Night were professional, trustworthy and cared about getting my house and family cool. They were very responsive - worked to keep my costs down - and even came on a Saturday morning to fix our unit. I had a great experience working with them, and they will be my go-to ac company from now on! Johnathan and Christopher could not have provided better service. Thank you so much! — Sarah A.

  • Day & Night is prompt, professional, and reasonably priced. Recently, the heater at my grandmother's house stopped working and the temps were plunging, and we needed help fast. These guys came out right away, and within 30 mins they had gotten the heater running. They also educated me on maintenance that might prevent the same problem in the future. I highly recommend this a/c heat company! — Derrol S.

  • Just when you need professional help, Day and Night came through! On an Aug Sat afternoon, my air conditioning began to steadily fail and that is time to panic. I called this service and they sent Jonathan to my house within an hour. He had the part and my problem fixed within any hour! Great. What is especially awful for me, is that I had my air conditioning serviced by John Moore on June 26, and they charged me $449.08 for doing nothing!! I have sworn off that company and now have a contract with Day and Night Thank you — Gwen S.
