Quick response, accurate diagnosis, clean, quick & courteous replacement of old gas furnace.

I don't have time to write reviews but I have to report how happy I am with Design Air. When our old furnace quit when it was very cold, I got a quick quote from a Paso Robles HVAC contractor. Their salesman was a bit high pressure but we held off and made an appointment with Ethan. He asked about our HVAC usage and offered a system that fit it. His offer was far superior in efficiency, durability, and functionality - and for considerably less money ! I took multiple, engineering graduate school courses in thermodynamics - Ethan knows HVAC ! Always get multiple quotes from contractors ! read more

Look no further....this is this business for all your HVAC needs! Ethan and crew Chris and Paul did a fantastic job replacing my old furnace and water heater. Olga communicated well about the schedule and relaying questions that I had to the team. I had 4 bids from different companies for my complicated job. I had some previous ducting work done during a remodel that was not completed properly. Design Air was the only company that addressed and corrected these problems. They were very professional and thorough. The workmanship was excellent. I would highly recommend this company for your heating needs! read more

Scheduled a complete replacement of our 45 yr old furnace and leaky ducting. Crew arrived on scheduled morning, finished ahead of schedule and worked incredibly hard for the duration. Not an easy job working in the attic. All were very polite and professional. I recommend this company as honest and providing quality workmanship. Thanks Ethan. read more

If you are looking for a truly Professional, friendly and fair HVAC contractor, look no further! Ethan and technician Nick expertly installed a multi-zone mini split system that exceeded my expectations. Olga kept me informed on scheduling and costs throughout the project. They are the BEST! read more

How do you know who to call, who to trust, who will fix it right. Ethan did it! He put me at ease, I told him the story about York the heater. Through a process of elimination the problem was determined to be a blown transformer. Ethan had a transformer in the van Wa La! I'm not sure if it was age or the power surge that occurred after the vacuum got a jammed motor and it smoked the outlet. The outlet for the heater is in the garage directly below the fried outlet. Hummmm I also discovered the power strip to the tv center got fried too, but it was an expensive one with the fuse built in so tv's saved! Anyways- back to Ethan mention the yelp review and get $30 off the service call charge. Ok, already call Ethan it's not fancy smancy just honest work for a fair price. Foodguy Martin read more

They came out as scheduled. Tech was good but office staff tried to OVERCHARGE. They were supposed to call me with a part # and never did. I called 2 x to get the part number and was given the runaround. Found the part # and it costs about $250-$275. They tried to charge over $850 for just the part let alone the labor to install it which would be extra. That is a RIDICULOUS markup on a part. GREEDY people looking to screw you for as much as possible. No wonder they never called back with the part #. They didn't want me to find out how much they were going to gauge me for. I would never recommend this company. Tried to get over and got caught. read more

Highly recommend this company. Ethan and Chris are incredibly professional, they did extra work for no additional cost. They replaced my 29 year old forced air heating system. read more

I needed to have a multi-zone split HVAC system installed at my mom's house. Ethan and crew installed it at a fair price and did an excellent job. Make sure you get a quote from them before you do any HVAC work. They are friendly, knowledgeable, and reliable. Great to have a contractor like that in the Neiborhood. read more

I hate it when I have to call a contractor for any job. I have a handyman that takes care of most of my repair issues for $35.00 an hour. I'm a senior on a fixed income and I'm paranoid about getting ripped off. Three weeks ago I called McBrides and they wanted $255 to replace the pilot light on the same heater that Ethan worked on. Ethan replaced the entire gas valve, a much, much, bigger job for $240. I called Ethan (the owner) at 1O:00 a.m. He was very straight forward on the phone. He arrived at 4:00 p.m. and had the part I needed with him. The others I talked to said they would have to order the part. He preformed the job in a professional manner and was very personable. I hope this is the last of my heater problems. I will call Design again if I'm unlucky. read more

Outstanding service/attitude First called for service and received immediate return call from Olga. She was very helpful. Appointment scheduled and Ethan arrived on time. He serviced 2 heaters and thoroughly explained the 35 year old house heaters downfall which was causing an extreme heating bill . A bid for a new heater was given and absolutely no pressure to buy one. After research i found both the product and Design Air to be quality. I called and requested his services. Appointment made for installation. Ethan and his assistant arrived on time, installed heater, took away old one, and cleaned up the area. I highly recommend Design Air (Ethan) for your heating /air conditioning needs. Very professional and very nice person read more

Fantastic price. Ethan came out to diagnose my heater. He took it apart. He made the fix. And he didn't charge me a cent more than the diagnostic price. I spent three hours with the owner's manual trying to diagnose the problem and I was stumped. Ethan came out and set it right in about fifteen minutes. Great experience. read more

Outstanding service Called them in the morning, Ethan was at my house by 2 PM, diagnosed the issue and ordered the part then scheduled the repair for the next day. He was prompt courteous and knowledgeable. I have plans to schedule regular maintenance with designair. and if I have any further heating issues will not hesitate to call DesignAir.. read more

I simply can't imagine going anywhere else! Olga in the office and Ethan and Chris in the field are as good as it gets. Totally professional, reasonably priced, on time, great communication, etc., etc. Ethan first tried to fix our 35 year-old Rheem furnace, but it only worked temporarily and had coughed its last breath. Then, they applied our repair cost towards the purchase of a new Trane furnace (same specs), doubled the size of our return sheet metal for better air flow, replaced the thermostat which was previously not included in their quote, and finally completed everything in just one day. We could not be happier with our new unit, especially on these recent very cold mornings. Thanks again Design Air HVAC! read more

Based on a neighbor's referral, we called Design Air Heating and Air Conditioning to check out our central heating system which was not working. They were on-time, friendly and professional. They determined the need to replace the circuit board which they did quickly and at a reasonable rate. Even better, when I called to say (mistakenly) that our heater was putting out cold air, Ethan came out on Christmas Eve to take a look. Turns out I've been using my system incorrectly for years. Ethan, was really kind in explaining what the problem was - and didn't even charge me for the call! SO awesome! read more

I originally found Design Air from reading Yelp reviews and couldn't agree more with what I read. Ethan and Chris were both prompt, polite, knowledgeable, efficient and did a superior job fixing and updating our system. They went above and beyond, kept me informed and provided excellent customer service. I highly recommend you give them a call for any of your HVAC needs. read more

Ethan, owner and operator, is fantastic. Listened to the problem, scheduled an appointment immediately (same day), showed up quickly (within an hour!), fixed the problem within 15 min.(failed capacitor which he brought to the job) and checked the rest of the system to make sure we wouldn't have any more surprises. Repair price was very reasonable! This experience is nothing like we have ever had with an HVAC repair group! Restores my faith in the service industry! We will be using Design Air Heating & Air Conditioning in the future. read more

Although I ended up not needing Ethan to come out, our A/C went out Friday and after reaching out on a Friday night, Ethan responded extremely quickly and his cost for coming out on a Saturday was great and lower than the person who we had already scheduled to come out. From his response and cost, I'd definitely recommend others to keep him in mind. read more

Outstanding service!! Called at 11am due to our air conditioner went out on us during this 105 degree weather we are experiencing. Ms. Olga called me back and Ethan was out to take care of us by 4pm. Actually came a half hour before original said time. Thanks to Ethan for cooling us down!! Would highly recommend Design Heating and Air for your next project. read more
