David Granillo and his assistant Robert arrived on time, were personable and professional, and cleaned up afterwards! Before David arrived, our kids were suffering from allergies and our HVAC unit sounded like it was gasping for air through a straw and now we have a free flowing air/heat circulating the house! He was reasonably priced and worth every dollar. David, it's official- you are my GO-TO-GUY when it comes to my central air/heat! read more

Sorry to say I am very disappointed in the continued repair of my heating and air conditioning Coleman system. We have had great service for repairs of said system, but now that we have had no heat of air conditioning for 2 months, we are very unhappy to say the least. Thought he was reliable but he has given up on us. What can be done? Very disappointed. Can this be righted? read more

Our central A/C was blowing warm during the latest heat spell. I called David. He came over by noon the following day, went to the thermostat, then to the outside unit, took the side cover off and said, "Yup, that's it." He removed the capacitor, left for his supply store, came back a half hour later, installed it, did some checking the unit with his instruments and declared, "Yup. That does it." I went inside, turned on the A/C and it blew cold. Next, I told him my minisplit wasn't cooling the way it used to. He raised the cover, took out the filters(which were very dirty), said rinse these off with you garden hose, let them dry. I did. Turned on the minisplt and it worked like new. Now our whole house is cool again. David is personable, knowledgeable, efficient, and reasonably priced. All in all, a great experience. Thanks, David! read more

David Granillo was very helpful with my A/C needs. He found the problem that I was having and fixed it. He also took the time to check out my system and correct any issues.

Called this guy 7 days ago (July 14) and left my name and number regarding air conditioning service. NEVER BOTHERED TO CALL ME BACK! BAD AND ARROGANT CUSTOMER SERVICE!!! Called Duarte AC and got an appointment and got my air conditioner up and running. Thanks Duarte AC! read more

I'm only giving two stars because the last time he provided service it was great. Otherwise, he'd get zero (if it were possible). I tried for two weeks to get this man to come to my house, and he just couldn't bring himself to actually get here. I left a voicemail, and when I hadn't heard back after 5 days, I texted him. He responded to the text, asking me about my schedule and I replied back. He never got back to me. I called and texted again with zero response. Took my business elsewhere. read more

David is incredibly professional and knowledgeable! He was able to not only identify the problem with my AC blowing hot air, but able to fix it along with a few other issues within an hour! I highly recommend David for any of your AC needs! read more

Thanks again Dave for helping my 80+ year old client Evelyn for selling her house for $57,000 over listing price! Because of your excellent service I was able to close on time and it's nice to have you on my real estate team. I would definitely refer you to my family members & clients and I look forward to our next deal... or round of golf :] read more

David came to check our A/C and was very thorough and straightforward. He went to check our A/C initially, what was working and not. He then came back and finished the job in an hour or so. Great and reasonable guy! read more

Truly a gem among service contractors. Finding Dave through Yelp! reminded me why using Anglie's List is a waste of time and money. i read Dave's 5-star reviews when our A/C unit stopped blowing cold air. It was a really hot day in August, and although he was busy, Dave called me back in an hour. He made an early-morning appointment for the next day, and showed up on time. The A/C problem was a $35 electrical contact piece that he replaced and reconnected in 15 minutes. Then, he cleaned the coils because they were laden with mud and dirt, thus making our unit less efficient. The bill was extremely cost effective, and I plan on hiring him to do some maintenance work on our other home A/C units after the summer temperatures abate. read more

Hi highly recommend David! I am an experienced local Realtor and have had the pleasure to work with a lot of handymen, contractors, HVAC specialist, you name it. I was extremely happy with David service!! He is experienced, processional and really goes above and beyond to diagnose the issues. My clients are purchasing a home in Duarte and the heater looked very old. We called David to come over to check it out, he took the time to go over all of the details and answered all of our questions. If your looking for an honest and experienced professional, call David...he's the go to guy! read more

I endorse David! He was very professional, was on time and didn't try to up sell me. He gave me suggestions. Very nice. I would 100% use him again. read more

If I could give David 10 stars on Yelp I would! I hired a large company to replace my patio with pavers. Unfortunately, due to a lack of careful coordination between the design architect (who primarily designs) and the project manager (who oversees the construction), it was pointed out to me very last minute that the air conditioning unit was in the way of the paving work, and the construction crew would not be able to move it to complete the job in that area unless I hired someone trained to unhook and move the condenser. I called many air conditioning companies, some that wanted to charge me upwards of $600-1000 just to unhook, move and re-hook the unit. David responded almost right away and not only provided a quote that was reasonable ($375), but asked all the right questions about the unit to gauge whether the work could be done. He carved out time in his already busy schedule to come out when the construction crew was on a lunch break to move the unit when I needed him. He even offered to go buy the base to replace the one I had that was broken. He was careful and efficient, and came back to re-hook the unit just when the weather was heating up after the construction crew finished. I thought that going with a big company for the paving work meant that I would be working with people who were knowledgeable and service-oriented, but like any big company I was faced with the bureaucratic nature of a large company with hoops to jump through to get what I needed as a customer. David is the real deal, and I would go with an independent contractor like him any day over large companies for air conditioning service. He's skilled (extensive experience in commercial and residential air and heating units), offers reasonable prices, and truly enjoys making his customers happy! I would not hesitate to refer him to my family, friends, and colleagues. read more

Very professional, knowledgeable and honest. Performs thorough maintenance with repair work and informs you of best methods to keep unit working like new. Would easily recommend him to others. Very pleasant personality. read more

Just got a new AC/Heater installed yesterday 4-17-18. I had problems for several years with my old AIRTRO which had a lot of leaks and freezing. Finally , I had new unit installed yesterday. I called David last week , made my deposit and he installed in less than a week after I made initial call. He arranged the crane- due to roof top on top of a townhouse to remove the old unit and replace the new one. He arrive a little after 845 am and was waiting for the crane which was to show up at 10:30 am. He stayed all day to get the old one removed and finally at 330 p.m. the crane arrived and he completed the installation before I got home that evening. The unit is great and runs well both heat and AC. David explains everything in detail and is very trustworthy. I would totally recommend his services. read more
