HVAC reviews in Modesto, California

Went through our home insurance for first time, needed diagnose of hvac system because we had little to no air and no cold air in the summer, came through, diagnosed and ordered parts, replace and fixed within a week, had new thermostats installed, cosmic comfort couldn’t figure it out, williams heat and air came back and crossed a wire, now we have heat downstairs!

Sure everybody hates when they're heating and air goes out usually the prices are outrageous but with these guys you don't have to worry about that their prices are fair and if you want honesty along with great work there the people to go to and that's more than a warranty

Wade. Thank you God and you for the fast, honest, and precise inspection of our HVAC. We as a family will highly recommend your services and continue to use them. Please look no further people, Wade can fix your AC problems. Thank you once more.

Had issues with my A/C and Williams Heat and Air was assigned to me by my warranty company. He called right away after I got off the phone with my warranty company and showed up the next morning. Fixed the problem within 20 minutes and double checked everything to make sure nothing else was wrong. Great company and very efficient.

I called our home warranty about our AC being within 8-14 degrees hotter than thermostat & they said they would be contacting me. I hung up & looked at reviews which were good. Within 25 minutes he called & said I’ll be there within 30 minutes. I couldn’t believe how fast he came out; replaced part that was defective & had it up & running within probably 40 minutes! Definitely recommend them for your AC & heating

My AC shut down when it was 104 degrees. It was the worst. My home warranty company sent my job order to this company. They came out the next day. The guy was super nice and professional. I paid him $85 with a check and it should have been $80. He called me the following day and let me know I overpaid by $5 and if he could drop it off. I thanked him for his honesty and told him I'm just happy my AC is working and to keep it. I could have saved myself $85 by just changing the filter... go figure!! Check your filter before putting in a service call.

Once again Wade got my AC up and running the same day I called. I have been using Williams Heating & Air for years and will continue with him in the future. Highly recommend.

Trying to charge for a false claim about the vent being closed upon arrival. This place is a scam. Please spend your money elsewhere.

after three phone calls leaving my name and number, I never received any responses. that is passport a business model as a person, whatever want

I could not get a rebate from t.i.d. Because I am still waiting for a receipt. And the Warranty of equipment installed. Paid with a check and No One ever called back! Don't use them. Bad service!

This company does amazing work. I have used them on multiple rentals and my personal home and I never have to question their work. They are very professional in every sense. Thank you Ragsdale.

They went above and beyond to make sure our heater worked the day they started the job. It was a big fix and they stayed late to make sure our family had heat for the night. Genuinely cared, would definitely recommend to friends and family.

Unprofessional employees and unorganized front desk. Paid for a new circuit board through an employee who just took the money, then the part when out not even 3 months later and the company can’t help me because they didn’t get the money even though I have every screenshot showing I paid their employee. Now being told I have to buy a whole new unit because the manufacturer doesn’t make the part anymore. Plus I was told even if I bought a part the part has a warranty of however long the unit has and their work is only warranted 90 days. Don’t bother with this company.

Our AC stopped working and they were able to be out within just a couple of days after we placed a work order with our property management. The company was very nice and responsive when I called to find out the status of service. The vendor came out and went above and beyond to ensure our AC was fixed for this heat wave that we are having this weekend. He could have made us wait for the part to come in but found the part went to another town to get it and came back to install it. I would recommend everyone that needs service to go through this company for their HVAC needs. We surely appreciate everything they did for us!

Dycus Heating and Air is the best in the business hands down. They’ve been taking care of our home for years and I’m always so impressed with how professional and knowledgeable their employees are. I would highly recommend them for your heating and air conditioning needs!

Dycus is always courteous, they’ve been our heating provider for a few years now and the service techs. are very informative and take the time to explain any concerns. Thank you Dycus!

Awesome service. The technician that came out was extremely friendly and very knowledgeable. He was extremely careful both inside and around our garden outside where the A/C unit is. Highly recommend Dycus both for the service and the pricing!!

The team at Dycus did a fantastic job with the addition of a split system for our ADU/gym. They were: professional (all of the team), courteous, their work is 1st rate! Working with them has been a 5 star experience. They will be our only heating & Air company. The bonus: the value and budget friendly cost. I can recommend Dycus 100% for your heating & air needs 👍

I would give this company a zero star if that was possible. Not only they have highest prices which i dont mind paying extra for good and professional services but when it comes to have the right attitude , I would mark this business a low quality costumer services. I did use their services when my ac went out , there was nothing wrong with my ac, we previously had done some remodeling at our house and we didnt change the air filter after remodeling , that caused our ac to go out. Due to having a older thermostat , we end up installing new thermostats how ever the ace still wouldn't turn up , it needed a jump start. How ever they showed up and jump started. Having my own thermostats, and changing one filter the bill was $455. Moving forward i decided to have them come up to do a maintenance on my commercial building. They booked me in a week later. On a day of my appointment , i received a text saying that they had to go for a emergency repair for somone eleses house. My original appointment was between 10-12. They said they’ll be there between 1-3. So 3:45 passes by still no show , then I recieved a phone call from one of their tec , the tec was very rude over the phone and telling me they he would arrive the latest 5:45. I mean common , thats why I booked the appointment for. Complete waste of time. . DO NOT USE THIS COMPANY AT ALL COST.

I can always count on Dycus when I have a heating or air conditioning problem. Quick service and great technicians.

Great company great customer service on time got the job done better than agreed upon and a fast timely manner would not hesitate to have them do another project for me
Thanks Dave and crew for a great job!
