Shaun was very skilled and professional. He and his protege worked, in the heat, tirelessly to repair our air conditioning system. Day to Day was able to complete the work for far less than the original installer. They overcame several obstacles without hesitation- stayed true to their estimate and finished on time. They will be our “go to” HVAC repair company from now on!

Nick arrived on time and finished in an hour. He cleaned our whole house fan system as it hasn’t been cleaned in about 4 years. He kept his work area clean and tested the fan after service to make sure it worked perfectly.

I don’t usually write reviews, but these guys absolutely earned it. I even waited six months before posting this just to make sure everything was still running perfectly and it is. From the first call to the final walkthrough, the entire process was smooth and professional. They showed up on time, diagnosed the issue quickly, and explained everything in a way that actually made sense. No pressure. No upselling. Just honest recommendations and clear pricing. What really stood out was how responsive and professional they were. My call was answered right away, and they had someone out the same day. The technician, David was clean, respectful of our home, and extremely knowledgeable. You can tell he takes real pride in his work. Since the repair, our system has been running better than it ever has — quieter and more efficient. We’ve gone through heat waves and cold snaps without a single issue. If you’re comparing HVAC companies, stop here. This is the team you want working on your system. Reasonably priced, reliable, and they actually deliver on what they promise.

Hands down the greatest HVAC company to ever exist. If I could give them 10 stars, I would. They didn’t just fix my AC — they restored my faith in humanity. I’m convinced their techs are part magician, part superhero. My house went from sauna to paradise in under an hour. Legendary service.

I had a wonderful experience with Day to Day! They were able to squeeze me in same day for a smart thermostat install and their pricing is very fair. They are now my go to HVAC company :)

David was professional and responsive. We went back and forth trying to identify the best heat pump for my needs. Once i found one, installation was scheduled for the next week. Installation went fine and took less time than originally anticipated. We had an issue with a clogged drain pipe and David came right out and fixed the issue. I highly recommend Day to Day Heating and Cooling.

One of my properties wasn't blowing out cool air. It was still a new build, yet we weren't getting service from the builder on time. David came quickly and got our air conditioning up and running in less than an hour, and provided us with plenty of tips on preventative care to help avoid future problems. He fully explained to me where my AC units' stats are and what they should have been. I would recommend him to anyone within the San Diego area and surrounding counties. Five-star service and very professional.

Day to Day is the best! My low voltage fuse kept blowing, and David ended up finding an electrical short in the contactor. He replaced it, and everything is working perfect. Highly communicative, friendly, and could not recommend more!
