Posted on Laura M.Verified My AC needed maintenance and ... it had stopped cooling. I called Day to Day and they were able to schedule within a reasonable timeframe and the cost is pretty good. They also installed a smart thermostat. My AC needed a little fix, he was very honest telling us what was wrong and how to check for this issue. I will call them now for vent cleaning next. Totally recommend !Posted on Luis V.Verified From initial yelp consultation to the time for service, David from Day to Day Heating and Cooling was courteous, professional, and diligent in the services performed. I reached out for a basic ac cooling service and touch up and David was able to get our system up and running like new, as well as take care of some other issues that came up on the spot. David was able to improvise and solve the issues, all with a reasonable price. We will definitely contact this company for our future ac needs. Thank you David and Day to Day Heating and Cooling!Posted on Hank S.Verified I can't say enough positive things about David. He is incredibly prompt, friendly, knowledgeable, and communicative. He identified the problem quickly, and made himself available to fix my AC the moment the broken part was available. His prices are fair. Very, very highly recommended.Posted on Ashleigh N.Verified David was super quick and responsive! He came out for the repair the next morning, was on time and came ready for the job. Very knowledgeable and immediately diagnosed the issue, showed me the issue and provided options for repair (our in-wall heater wasn't working). Price for replacement and labor was fair and made easy for both parties. Definitely recommend and will be contacting him again for future issues!Posted on Erin M.Verified David was professional, easy to communicate with, very transparent and reasonably priced. I had gotten other quotes from larger companies for some seemingly simple maintenance and felt like each technician was working for a commission to upsell me, not to give me what I actually needed and make a happy customer! Next time I have any maintenance needs or repairs, Day to Day will be my first call!Posted on Rainnier G.Verified I highly recommend Day to Day. We needed sediment traps installed on a couple of furnaces to meet home inspection recommendations. As we are in escrow, we needed the project done on very short notice. David from Day to Day was the first vendor of many to respond. After fielding several vendor quotes, we felt most comfortable with David's estimates and timeline. He walked me through a couple of options, got out to our property the next day, was very friendly, professional and completed the project in a reasonable time. He was thorough in explaining the details of the project and even took photos and videos for our realtor. I have nothing but positive things to say about David and his company. My family and I are very pleased with the outcome. Highly recommended!Posted on Andrei B.Verified FIVE STARS!! David was very knowledgeable and helpful right from the start. He was very accommodating and was open to exploring different ideas and cost effective ways to fulfill the project. I confidently recommend Day to Day to anyone in need of AC solutions!!!Posted on Jenny K.Verified We accidentally bought a fixer upper. When the old HVAC system flooded our attic, we were at our wits end. Shaun and the guys at Day to Day were recommended to us by our water remediation folks. They came out, diagnosed the problems, and then worked with us to install an entirely new HVAC system through the whole house. I do mean *entirely new* - ductwork, moved and added registers, whole new compressor, new furnace. They worked quickly and professionally and took amazing care of our home every step of the way. Our insulation guy came back after they finished, and went out of his way to compliment how nicely the ductwork had been done in the attic.Posted on Nick G.Verified My thermostat wasn't working properly so I called Day to Day. They were responsive and made the appointment that same day. I highly recommend them. David took the time to explain what was happening. I'm a happy customer.Posted on Micah B.Verified Professional, thorough and honest. Shaun and his team does great work. We were very impressed with his help. Our HVAC system is very old and had many issues. Shaun and his team gave us honest advice so we were able to make the best decisions for our home. I would highly recommend this team to anyone and will only use them in the future.Load moreVerified by TrustindexTrustindex verified badge is the Universal Symbol of Trust.
