The AC is now blowing cold again and working great. Justin was very professional, explained everything clearly, and completed the work efficiently.

Thanks again for getting our home cool and comfortable again !

We had a new unit installed at our old house years ago by Fred. They did a phenomenal job then…read more However this review is from today. I texted Fred yesterday, on a Saturday, because our unit in our new house (Not the one he installed) was having some issues. He came out on a Sunday and fixed it in 30 minutes, and DIDN"T charge us. I am not saying that will always happen, but Fred is stand up guy who stands by his work. Solid guy, he deserves all your HVAC business.

Fred texted me Friday saying he couldn't make it due to an illness. He offered to come in Sunday if he was feeling better. I agreed. He showed up at the agreed upon time which was typically his day off. He was very friendly and communicative. He fixed the issue at the proposed cost and explained what he did and next steps for us in operating our heater. Great experience. I'll definitely reach out again if ever needed.

I got the Mitsubishi mini-split installed at a decent price and it looks and works great. Know that…read morethe cell phone cannot operate the mini split app unless your phone has 2.4G capability. The installation was good but... 1. A remote control was placed between a light switch and the door. You need to turn on the light before you use the remote, preferably w/o scraping your knuckles. 2. A pile of trash was left behind. I forgave that since the three men worked hard for more than 8 hours. 3. After they did wiring in my attic, insulation started falling through the kitchen ceiling vent. I pointed it out and the installer vacuumed the vent from below. I said it would be better to blow it, but he said it would be fine. It continues to fall down thru the vent. 4. Old HVAC vents were blocked to keep the warm air in and cold air out, but they left a big one in the old HVAC closet. Also, they capped the gas pipe inside the closet, so there are two holes to the outside. I could have made the closet look finished if they had capped the pipe below the house. 5. The way they inserted the cable ducts through the foundation air vent was poor. Rodents can now enter. 6. Poor oversight and communication. I wanted easy things corrected that would take 20min. "Mark" promised someone would get back to me...they never did. I called/texted about 5 times. Finally he stopped responding.

The team arrived on time, explained everything clearly, and completed the installation with exceptional attention to detail. The quality of the workmanship is outstanding, and it's clear they take pride in doing the job right. I'm especially grateful we had the new A/C installed before this weekend's heat, it has already made a huge difference in the comfort of our home. If you're looking for a reliable, honest, and knowledgeable HVAC company, I highly recommend Renner Heating & Air Conditioning. Excellent customer service, quality work, and a great overall experience. Thank you for a job well done!

After 25 years, my Concord home needed a full HVAC replacement. I did my homework -- four quotes,…read moreverified equipment certifications, asked hard questions about duct sealing, zoning, and equipment sizing before deciding. A-1 answered every question confidently, corrected a spec error in their own quote when I caught it, and put everything in writing before I signed. Install day: Austin, Joey, and Edgar showed up on time. Floors covered, shoes covered, house treated well. Two days -- day one removal and new equipment, day two ductwork and zoning. Heating and cooling tested before they left. Full documentation handed over on the spot. No hidden charges, no surprises, no change orders. Price was mid-range among four quotes, but the warranty structure -- lifetime workmanship, no-lemon guarantee, payment at completion -- made it the best overall package. Still have HERS test-out and city inspection scheduled, but based on every step of this process I'd recommend A-1 without hesitation. Austin, Joey, and Edgar did a great job.

He detected and replaced a blown capacitor and got the A/C working right away. He measured all the components of the system outside and tested the cooling effectiveness inside the house. He was happy to have me out there as he worked and explained everything he did. What he did not do: upsell / recommend a new system install. Though he did explain that our 22 year old unit was likely reaching the end of its service life. These guys are very straight shooters in an industry with some sketchy common practices. Price for analysis of both systems and the repair of 1 unit was very reasonable.

Beware this company! They dont clear charge you before the service!…read moreWe had a very disappointing experience with this company. Their technician came to our home to look at our heater. He did not provide any upfront pricing, nor did he tell us that there would be a fee before touching the unit. After doing a quick, simple adjustment, he charged us $125 without any prior notice. The heater only worked for a one time and then failed again the same day. When we called the company, the owner told us that our heater is "over 20 years old and cannot be repaired." If the unit was truly too old to repair, their technician should NOT have started any repair or charged us in the first place. This is misleading and unprofessional. We feel that this company did not follow proper business practices: * No upfront pricing * Performed unnecessary work * Charged without consent * Refused responsibility afterwards

After two repair, unfortunately, the issue was that my system was just too old and needs to be replaced. They gave me a quote within a few hours (totally reasonable after received competition quote). Accept the quote on Thursday afternoon before 7/4 long weekend, and David was able to help me getting schedule first thing Monday morning!!! The installation team is professional, efficient, and friendly. Highly recommend!!!

I like how they take their time to explain what they are doing and also give tips on how to maintain your HVAC system. This review is for my most recent experience with All Weather. I am a realtor and needed a HVAC inspection ($150), so I call All Weather since I had a great experience with them before for my own HVAC system. Art (Arturo) was assigned to the inspection. An email (with the tech's name and picture) and text was sent when he was on his way which is nice. Art did not rush the inspection and was very thorough. He took time to explain what he was doing and what he was checking for. Also took time to explain what maintenance items needed to be completed. Then provided a thorough report of the maintenance items needed and cost if they were to perform them. Overall, I am very happy with their service and their technicians' knowledge and professionalism.
