Kevin installed a new HVAC and ducts; the system would shut down because the ducts were installed incorrectly causing the HVAC to shut down because the heat was backing up! After years of asking Kevin to correct the issues, he suggested another company, this company agreed that the ductwork is installed incorrectly and causing the unit to shutdown after 3 minutes, which then blows air. And the unit still under Kevin's warranty and he won't honor it. Beware my neighbors read more

Awesome service! Our AC died in the middle of the afternoon on a day where the high temperature in Martinez was 104. I spent the rest of the day and most of the next day calling various AC contractors, trying to get someone to look at my system, with no availability for 2 days. When I contacted Kevin, he responded in half an hour and asked if he could come "now." He had identified the failed part (capacitor) in about 2 minutes of looking at the system and went and got the part and had it installed in less than an hour from when he arrived at my house. read more

Kevin is simply fantastic. After coming out for free to inspect our broken AC Condenser he tried VERY HARD to fix it first before we realized it was beyond repair. He knows how expensive replacing a system can be. He was extremely professional and knowledgeable about what our options were. He gave me several tips and realized our ductwork was not optimal and fixed it for us which was a big bonus. Now our new way more energy efficient system is blowing cool and warm air so much better that it did before. Kevin has a great positive attitude and is a true gem. He is very affordable and guarantees his work. I could not be happier I chose Kevin to do our new HVAC system. He also lives in my town and I can always count on him if I need help. read more

Living in Martinez, I wanted to support a local contractor so I chose Wendt Heat & Air. In the end, it was clearly the wrong thing to have done. I will admit Kevin responded quickly, but he started by replacing parts that did nothing. Then he had to start calling his friends for ideas. He finally said the compressor was bad. He said he had to get the compressor under warranty from Trane and it would be a week. We were going to be gone for two weeks and gave him permission to go to our house and replace the compressor. He said it would be done within a week. 2-1/2 weeks later, he hadn't done anything. He was too busy. Finally I strongly suggested he come out and finish the repair and he did. As soon as he was done, he grabbed his check and high-tailed it away. At that point, I wasn't going to post anything... just let it go. The air conditioner ended up performing miserably. We sweltered in the recent hot weather and I ended up going with a friend's recommendation to use JB Air out of Pittsburg. John did a thorough analysis, told us we had too many filters, which was restricting airflow and icing the compressor. He then checked the level of R-14 refrigerant and found that Kevin under-charged my system. He used the minimum amount based on a short line and it wasn't enough. John evacuated the refrigerant, checked it for leaks and recharged it fully. I now sit comfortably in my home, and not in 80 degrees as before when Kevin fixed it. I heard excuse after excuse with Kevin and he didn't fix it. I got results immediately with John at JB Air and the system works! read more

Finally, air at last! I was referred to Kevin (the owner) by a family friend and couldn't be more pleased. My unit had completely died on me. I was really worried I was going to have to replace the whole thing. Luckily, after Kevin came out, he told me that only a part needed replacing. He promptly got the part and installed it for me the next day. He was honest and fairly priced. You never know when someone is trying to get over on you and I felt confident with Kevin. I can tell that he is really busy because he had several phone calls while he was installing my part. Based on some of the previous reviews I think I can understand what they went through. I don't think its intentional, however. It was actually kind of funny that he mentioned he's looking to hire someone for the front office to help with calls and appointments. I happened to refer my aunt for the job (so random). I got a free assessment of my unit's overall performance, as well. Turns out my furnace is a piece of garbage too. I guess when the time comes, I'll be calling this company once again to ensure efficient, reliable service! read more

I would not recommend hiring Kevin Wendt for your Heat or A/C needs. Kevin Wendt did not fulfill the contract we paid for. Kevin's brother installed our heater in December and part of the contract was that Kevin would then schedule an inspection. However, Kevin has not completed the job we paid for. It has been very frustrating to need to contact him several times over the last 5 months to remind him to schedule the inspection and then to have him repeatedly state he will schedule the inspection, and then he doesn't do it. I wish we had chosen an honest business person who would fulfill their contract. We were thankful to find an affordable price for a new heater, but it would be worth it to hire someone who charges more who will finish the job they agreed to do. read more

I'm not really sure how many stars to give here so I'm just going middle of the road. The day after I wrote my review Kevin emailed me with my estimate saying that he didn't realize receiving my quote was such an urgent matter that it couldn't wait a week and that he was "bummed" by my 2 star review. From my perspective, I'm going to pay several thousand dollars for equipment to be installed in my house and I want to work with someone who communicates effectively and does what he says he'll do. Simple as that. He wrote me a 2nd email saying that his reviews reflect the work that he does, not his office work. I get it. I'm sure his work is fantastic. But THIS review is based on the quote process, not the physical work done. I don't NOT recommend him, I just chose to go with someone else and wanted to share my experience. read more

4/2016 update below ---------Kevin is honest, hard working and very knowledgeable about virtually all things A/C. He was prompt, courteous & extremely reasonably priced for the quality of work that he provides. He know my AC system inside & out & fixed my issue in no time. Should I ever need any further AC/Heating work done, Kevin will be my first call. ____________________________________________ Update less than a year later, how can you give a business excellent ratings If they don't return calls for work on the systems they fixed. Very disappointing. read more

Short Summary: Excellent HVAC contractor. Longer Story: I hired Kevin Wendt (the owner) to replace duct work to 3 of my downstairs registers. Our duct work was an old flex tube type that had been torn apart by rats. We had very poor air flow to the three ducts. Kevin came out to my house and looked over the work to be done and gave me a very reasonable estimate. We agreed on price and set a date for installation. Kevin and his employee came out to the house and completed the work within part of a day. We saw fair improvements in the air flow, I paid for the work, and Kevin and company left for their next job. Though the improvement in air flow was good, I still had some concerns I thought should be addressed. I called Kevin and he was immediately responsive, even though he had already been paid. He set a date to come back out and address my concerns. Kevin and his crew came back out to my house and reworked the duct work to allow for improved air flow. After completing the work, the three ducts pushed air like a hurricane, a huge improvement in air flow and efficiency. As I write this review, it has been over a month since the duct work was completed and we just received our first PG&E bill. The bill was 1/3rd the amount for the same period year-over-year. I was amazed. The duct work will pay for itself in less than a year. Kevin is an excellent contractor and I highly recommend him to friends and neighbors. He stood by his work (even after being paid) and addressed any concerns I had. read more

The heater just stopped blowing:-\ After one call, next day appointment, a return with the part, all on time and conveniently scheduled... and performed at a fair price... I'm 100% happy!!! Nice guy (Kevin), friendly and professional. Would definitely contact again, if needed. read more

Kevin the owner was great,affordable,and would highly recommend Wendt Heat & Air Conditioning to all my family and friends. read more

Kevin is the best HVAC guy you want installing your heat/air! Very friendly, professional, knowledgeable and an expert in the field! We are so happy with our new systems and would recommend Wendt Heat and Air for a new system or servicing!!! read more

Kevin is very professional and provides prompt and reliable service at reasonable prices. He arrived promptly to install a new compressor and kept us apprised of each step in the process. The job took various hours and we finally had cool air again. Kevin even came back within 2 days to install a coil in the attic to ensure a fully functional system. Kevin, thanks again for the great experience, Taide and Mike read more

My AC compressor was dead - Kevin answered the phone on a Saturday morning (the previous 5 places I tried didn't answer!) and said he would be there within an hour. He arrived 45 minutes after the call, fixed the issue (bad capacitor) in about 10 minutes. Fantastic service, highly recommended. read more

I couldn't be happier with my new Heat & AC system that Kevin and his partner installed recently. I had been in dire need of a new system for years but the quotes I had gotten were way beyond what I could afford so I stopped using it and had settled for a couple portable AC units the past few years. I dreamed of someday being able to upgrade back to a central system and next thing I knew my prayers were answered. Wendt came to my rescue and gave me a reasonable quote I could not resist as it was thousands of dollars less than what I had previously been given. The rest is history. Now my comfort level at home is "through the roof" and my condo heats up or cools down in a snap. In this day and age it's hard to find business owners with integrity and who are about pleasing their customers and giving top notch quality service (with a smile) along with affordable prices. I still can't believe how neatly they installed my new system. It is beautiful and I recommend this company without reservations because they are truly amazing and take tremendous pride in pleasing their customers. read more

I like this guy. Most professional and honestly person . Did good job and clean . Fix our gate for free even if we never asking him to do that. 5 star for him . read more

Our AC went out on the first super hot week of the summer. I thought maybe we'd stick it out and wait for my cousin, who does HVAC, to come out and fix it on Monday. But come Saturday 4pm it was unbearable and I started calling around to all the local companies, Kevin called back promptly and came out within 45 minutes! Shortly thereafter our AC was working again! The cost was very reasonable as well, especially for a short notice Saturday evening fix! I was thrilled! My two little ones could sleep comfortably! He was also very friendly and professional, I will definitely recommend him to my friends and family! read more

Kevin did an excellent job replacing our entire HVAC duct system. The job was more complicated and took more time than expected but Kevin and his crew always maintained an excellent attitude. They cleaned the job site completely and did extra work above and beyond without charging (like cleaning up our crawl space which was an absolute mess). He also rebuild the union around our furnace. Hard working, dependable and reasonably priced. read more

I can't say thank you enough for Kevin who despite how busy he is, he kindly came to a rescue! My AC broke on the worst day you could imagine. It's a 100 something degree outside and it's even hotter inside. As expected, I tried to call all the AC repair services around the area and they booked out at least 2 weeks. Almost hopeless, Kevin answered the call. He promised me he would come to my house today and he kept his word. After about 45 min, our AC started running again!!!! He is very friendly, and come with professional equipments. Thank you soooo much Kevin. You are the reason we "Live comfortably" tonight. : ) read more

Kevin is a true stand-up professional, I highly recommend his work if you live in the Martinez/Concord area. It is easy to tell he does this for a living, and has been doing so for a number of years. I will certainly give him a call the next time I have HVAC issues at my property. read more

Kevin came over within an hour of my call and went right to work. A really friendly guy who is really good at explaining what was wrong with my AC. We decided to replace to unit since it was so old and he did it for a very, very reasonable price. I would 100% recommend him to anyone who is having any ac problems. read more

Our furnace died and I called in a panic. This was in January and it was cold and wet. I was given a void price and it was installed in 24 hrs. New heater/ air conditioner is saved us $100 a month in energy costs too. read more

Kevin Wendt installed a new furnace for us, and we are thrilled. Arrived early, worked hard, and did a great job. We highly recommend him!! read more

My husband and I were very grateful for the service Kevin provided. He went above and beyond and will definitely be getting our return business. Our heater went out with no notice and Kevin came out as soon as he was available. He worked hard and consistently until the project was done and the heater was fixed. He replaced floor boards and insulation as well as the heater and cleaned up his mess thoroughly as well as giving us a great warranty and deal on the service. Would highly recommend!!!! read more

I called three companies to replace the furnace ducts in my El Sobrante home. All three arrived, two provided estimates (one didn't call back) and Wendt was less expensive and seemed more knowledgeable. My research indicated everyone used the same ducting material (flexible with bubble-wrap type insulation already in place) so the difference was all labor cost. Kevin and one helper (Tony?) did the whole job in a long day - not even a break for lunch! Then they took away all the old ducting and left everything clean. Each duct has a baffle at the furnace so I can adjust the flow at the furnace as well as with the vents in the wall. This allows me to even out the temperatures in the house. Previously, the rooms furthest from the furnace were colder than the rooms that were closer. My impression is that Kevin is a genuinely nice guy so I gave him a pass for being chronically late - he missed our first appointment (for the bid) and had to reschedule another one so you might have to be flexible. Because he's willing to help people with furnace emergencies, non-critical work may slip a little. I'm happy to support that behavior, but if you are on a tight schedule, you should probably let him know up front. read more

Kevin was Dr. good game but didn't come through in the clutch is work failed and he never return my calls or text let me I am dry I had to hire another person to come back and fix the things that he did wrong deafly would not recommend them read more

Our AC wasn't working during this past heatwave and after making a ton of calls, Kevin said he could come check it out that day. He came back the next day and fixed our unit for less than his original quote! He is a straight shooter and hard worker. Thanks again Kevin! read more

Kevin is a great professional man, honest and dependable. He came out to see my air ducts cause I thought they needed to be cleaned. They did not other than basic vacuuming, which he did for me. He did not want to waste my money. Now that is a decent business man. He did a list of other items and then some, All preventative for me not to waste my money on heating my new home. That was just FABULOUS. I have other things down the road to take care of in my home.. Wendt Service will definitely get more of my business. And he is a Martinez Guy, Keeping the economy going in our small town.. that is the best. Thank you Kevin. read more

First we had Kevin do an inspection on our house before we bought it. Then we had Kevin replace our rat-holed return lines and install a new Day & Night package unit. Top notch guy. Excellent work. I would recommend him to everyone. read more

I called Wendt after receiving a letter stating I have to pay for some HVAC repairs on the building I lease. I thought the repairs sounded a little fishy and called for Wendt for a second opinion. Sure enough it really does sound fishy and now I have some facts to take to my property manager read more

Kevin the owner is amazing! Our ac went out on Saturday and we were having a party so my sister looked up a ac repair company from the phone book. Those guys came out and quoted us an outrageous amount so we decided to look else where which is where I called Kevin who is a God send a truly honest man he even tried letting me take pictures of our unit and see if he could help immediately over the phone although he couldn't he was able to come out on Monday and repair our ac unit for a nearly a quarter of the cost of the 1st guys! This guy is such a honest guy! If you or anyone is looking for their ac to get fixed this is the guy! read more

I have had Kevin work on my HVAC system a couple times with all positive experiences. While the problem was initially not resolved on his first trip, he came back at my convenience to continue trouble shooting until the uncommon issue was resolved. In addition to professional service, the availability on short notice was unsurpassed after a few phone calls initially led me to call for service. While I have little experience comparing rates and costs, I have always felt I was charged a very fair price. read more

We had Kevin come out to service our AC. It turned out rats had totally destroyed the duct work. Kevin and his buddy worked very hard and efficiently to fix the problem. He pulled out dead rat ,maggot infested carcass from one of the vents! I know totally GROSS!! Kevin replaced all the ducts... as of right now our house is cool, no smell.. Almost like a new AC system. This guy is a total lifesaver and money saver . Very pleased with the quality of workmanship. My husband was so impressed he wants to send a thank you gift to Kevin. Now you don't hear stuff like that every day do you? read more

We had Kevin work on our air conditioning system. While the problem couldn't be diagnosed initially, Kevin was very persistent in troubleshooting the issue it until it was fully resolved. He was professional , courteous, and very conscientious of us and our needs. His rates were very fair. read more

Quick reliable service. Kevin re-did our ducts a few years ago and we called him again this past weekend when our AC stopped blowing cold air. He was able to come that same night (on a very hot weekend), and get the issue fixed. Fast, reliable and reasonably priced! read more

0 stars. Kevin is unreliable, unprofessional and not trustworthy. After spending over $5000 on a complete new system that only worked for two days, he has failed to meet his labor warranty, has failed to respond to phone calls or texts for three weeks. I believe drug use is prevalent here and I would be very concerned about your personal effects or allowing him access to your home. I now have to hire and pay a separate company for what he failed to do. I have filed a complaint with the California contractors board. BEWARE!! Professional scam artist at work here. read more

Great customer service! Called Kevin around 11 am and he said he could come same day. We were leaving at the time and asked for the next day. He was available and also said he lived local as well. We asked if he could come around 6 pm when we got back as I didn't want my aunt to be without heat for the night. He came over and assessed the situation for free. He was so friendly on the phone and in person as well. Very professional and considerate. He didn't have the parts needed on his truck but could do the job the next day as scheduled. He gave a very fair price and finished the next day to complete satisfaction. I must add that he kept his dinner waiting to accommodate us. He now has 2 future customers! read more

Kevin Wendt re- did our entire HVAC system during a remodel. He was fair, honest and very hard working. He does not waste time and is there as soon as he can be when you need him. All the materials were quoted in the cost, which was very reasonable. In the past year he has helped us with numerous jobs working on various rental properties. Our renters have also only had good things to say about him. He has come out to help modify our system to enable more air upstairs into our son's bedroom for no charge. He even gave me a Carbon Monoxide detector after he realized I didn't have one in the correct location! Very friendly, very professional, and highly recommended. read more

Our A/C went out after a week of being moved into our new house and with a 7 month pregnant wife and a 1yr. Old daughter it was pretty miserable. When we called Kevin answered quickly and got us an appointment the same day. He was very straight forward about about what needed to be done and gave us all of our options. He wasn't like the other companies who immediately tried to sell us everything new at high rates compared to Kevin. He did all repairs within the same week and repaired it all in one day. We had our a/c and furnace replaced and he went above and beyond our expectations in repairing it. He was very friendly and wants to do nothing but help. read more

My AC stopped working during the recent heat wave and I was looking for a smaller AC repair shop so that I can deal with the owner directly - typically my preference. Reviews for Wendt Heat & Air Conditioning were great and the description of Kevin and his work was exactly what I was looking for. I called in the morning, Kevin answered and explained that he is doing an installation all day, but will be happy to come by at 5PM (the same day). He called me again around 5 and apologized for being delayed at the previous job site. He got to my house within the next hour and promptly figured out the issue and had my A/C running in about 15 minutes. He was professional and courteous and the fee was fair. What else can you ask for? I already passed Kevin's business card to my co-worker and he is now my go-to guy for all A/C and heating issues. read more
