Customer Reviews

“Calvin and Jacob helped a ton to replace my broken AC in the summer heat. Very friendly, professional, and personable, too... plus a great price. Hard to beat! I highly recommend.”

“Calvin was a rockstar on this project! Purchased a fixer-upper built in the mid 1800s with no current AC. His professional team helped quickly install our AC and actually figured out how to get everything installed on a very old house. We went with the 15 seer unit hoping it would not disturb our quiet yard and this thing is almost silent. Absolutely zero issues with the unit at this point. Again, Calvin and his team are amazing and go above and beyond for their customers. Cannot recommend them enough!”

“Calvin and Jacob did a fantastic job on our new AC unit. They even fixed a couple things on my new furnace that a different company installed plus he gave me knowledge about how to take care of both of my systems would 100% recommend Covenant heating and cooling. Oh wait I already have thanks Calvin for being professional and kind!”

“Great company to work with!! Calvin and Jacob were very responsive and quick to help us out with our AC troubles! Would definitely work with them again and recommend Covenant to anyone who's looking or asks!”

“Our AC went out and Calvin did everything he could to solve the issue even going above and beyond to get us relief from the heat! Highly recommend.”

“Walked me through how to replace the part myself, very helpful and friendly.”

“Thank you Covenant Heating and Cooling! We bought an old farmhouse without an AC unit. After a quick home visit we had a brand new unit installed within a couple days. If there were any issues we didn’t know it, they handled everything with utmost professionalism and care. Came highly recommended and did not disappoint! 👍”

“Calvin from Covenant Heating & Cooling was fantastic to work with. He showed up right on time, was professional, friendly, and clearly knew exactly what he was doing. He quickly diagnosed the issue with my leaking AC and efficiently got everything under control. What really stood out was how honest and upfront he was. That level of transparency and customer care is hard to find these days. Highly recommend Calvin and HVAC Master — I’ll definitely be using them again!”

“Calvin and Jacob were a dream to work with! They got us in with 24hr notice, when other companies were giving us days to weeks. Jacob got us cooled down within a few hours! He was friendly and professional the entire time. Couldn't have asked for a better experience.”

“Covenant Heating & Cooling truly lives up to its name. Honest, humble, hardworking, and committed to doing things the right way. Our A/C replacement was handled professionally from start to finish, with excellent communication and quality workmanship. It's refreshing to work with a company that values integrity and customer service as much as they do. Highly recommend!”

“Great service, highly recommend”

“What a great service! Took care of the problem despite being holiday day! We are very pleased and highly recommend them.”

“⭐⭐⭐⭐⭐ Exceptional Service on a Holiday! I cannot recommend Covenant Heating and AC highly enough! We found ourselves in a stressful situation when our system went down on Memorial Day, but the team turned our day around immediately. It is rare to find a company that prioritizes customers over everything else, especially on a major holiday. Not only did they respond quickly, but they were also incredibly honest and professional. Instead of pushing for expensive replacements, they genuinely tried to save us money and explored every option to get us back up and running efficiently. Their customer service is truly top-tier—polite, transparent, and skilled. They didn't overcharge for the holiday visit, and their integrity really set them apart from others in the industry. Covenant Heating and AC has officially earned a customer for life. They are my new "go-to" for all heating and cooling needs, and I will be recommending them to everyone I know! God bless!”

“We heard from one vendor there were issues with our A/C unit. We contacted Calvin at Covenant Heating and Cooling and he called back immediately and came by the next day. He did a thorough checkup and was exceedingly knowledgeable. The other vendor wanted to charge beaucoup bucks for repairs that Calvin told us we did not need. Calvin also offered to stop by when the weather warmed up to be sure our A/C is working properly and did not even charge for this service. We recommend Covenant highly and if there were more stars, we would include them!”

“I had such a great experience working with Calvin at Covenant Heating and Cooling. He was quick to respond. My furnace wasn’t working. He was very respectful, super knowledgeable and very passionate about his work. I was very impressed that he came over the next day after contacting him. Found out it needed to be replaced. He got it all done the same week. Everything was working amazing. Thanks, Calvin! For working with our family and our crazy barking dogs :)”

Very honest and not pushy to sell us on anything extra. Just a great and honest business very rare to find these days huge thank you to them we would highly recommend to anyone!”

“Calvin is amazing! He saved us this last winter when our furnace stopped working and we were out of town! He did everything over the phone and even offered to run to get space heaters if the furnace wouldn’t have been done on time. The new one has been working great, and we would have been fixing frozen pipes had he not been there for us. Thanks again Calvin!☺️”

Thank you, Calvin and Caleb!!!”

“Great guy and Great work. Will highly recommend.”

“I have utilized Calvin’s company on two occasions, and each experience has demonstrated a consistently high level of customer service. Most recently, when my furnace stopped working on a Saturday afternoon, I contacted Calvin and he arrived at my home within an hour. He promptly diagnosed and repaired the issue with efficiency and professionalism. Calvin is honest, reliable, and fair in his pricing. I highly recommend his company and look forward to continuing to work with him in the years ahead.”

“I recently had the chance to connect with Calvin and was genuinely impressed. He’s thoughtful, honest, and clearly takes a lot of pride in his work. You can tell right away that he cares about doing things the right way and serving homeowners well. He communicates clearly, answers questions directly, and doesn’t come across as pushy or sales-driven, just knowledgeable and straightforward. What stood out most is that he’s the kind of person you’d feel comfortable having in your home. He takes responsibility seriously and approaches his work with integrity. In an industry where trust really matters, that goes a long way. If you’re in need of HVAC work in his area, Calvin is someone I’d absolutely recommend reaching out to.”

“I submitted a project request on Thumbtack to have a whole home humidifier installed. Calvin was the first person to get back to me. He came by a few days later to explain the options along with the quotes. It was quick, simple, no frills, no upselling, non-pushy experience so I decided to work with him. Less than a week later, Casey came by and installed, test ran and gave me a quick rundown on the system, all in under 2 hours. Best of all, the post job clean up was immaculate! Overall, great small HVAC servicing company doing honest work; wouldn't hesitate to work with them again”

“Forget those big companies that try to squeeze every penny out of you that they can! Seriously, this is the only guy to call. Had him out to look at my air exchanger, he provided the best service and the price was unbeatable. Very diligent, great communication, great follow through, and really knows what he’s doing. I will definitely recommend to anybody and everybody - great experience! Thank you Calvin!!”

“Calvin did amazing work. Very pleased with this company and the price was very fair. I have already recommended them to friends and family.”

“very kind and helpful what a nice young man I will use him everytime I need him”

“Had such a great experience working with Calvin at Covenant Heating and Cooling. He was quick to respond, he was super knowledgeable and seemed very passionate about his work. I was very impressed that he came over on Friday night, tried to fix my very old furnace but ended up needing a part, and came back out on Saturday morning to install and ensure everything was working properly. No waiting through the weekend. Thanks, Calvin! So happy to be warm again!”

“There are so many good things I could say about the owner, Calvin. From start to finish he is honest, professional, and knowledgeable. It’s rare to find someone/a company that truly cares about its customers, and he absolutely does. I highly recommend Covenant Heating & Cooling to anyone looking for reliable, trustworthy HVAC service.”

“Calvin with Covenant Heating and Cooling is amazing!!! I came home from work to a furnace not running, I called him after 7pm on Tuesday night and he was at my house by 8:30pm, and I had heat by the time I was ready for bed. He was very friendly and personable. It's great to find a company that is willing to actually fix what is wrong, rather than trying to sell you a brand new unit. I will be using Calvin for any of my heating/cooling needs in the future.”

“I had a complicated HVAC issue that two other companies didn't even want to take on because it required moving equipment for a remodeling project and required extra problem-solving. This company stepped in without hesitation, handled the job professionally, and made the whole process stress-free. If you're looking for an HVAC company you can trust - one that values trasparency and integrity, COVENANT HEATING & COOLING is the one to call!”

“I am a new homeowner...... in the middle of Winter my furnace starts smelling and making a loud humming. Of course, I panick. It's Monday...After calling numerous "city" companies and not getting help until at least Wednesday. I called Covenant Heating & Cooling and Calvin took my call. You know what he said "I can be there in 30 minutes." He showed up within 30 minutes. He was knowledgeable and respectful! And most importantly he was affordable and local!

“Calvin is wonderful to work with. Great tech and also has good business and people sense. Top notch communication and reasonably priced. My blower motor stopped working around midnight, put a call with Covenant and got a response back at 4am. He diagnosed the issue, went and got the parts and I was all up and running with heat by the afternoon. He kept me updated via text every step of the way. Highly recommend.”

“Our heater went out on Friday and I called Covenant Heating &Cooling at 4:25, and Calvin came out at 5:45 on a Friday night to fix it. He had to get parts that night, and it was around 9pm before he was done. Thank you so much for going above and beyond!!!”

“Shout out to the crew at Covenant Heating & Cooling for installing my new furnace today! Calvin, Trent and Casey were knowledgeable, friendly, and kind. The owner Calvin took the time to listen to the need and explain the options, giving a quote onsite during the first visit that was lower in cost than anticipated. No pushy sales, just honest, and real. Because of the great work at my house, my parents decided to get their furnace replaced by Covenant also! Check out this new christian based heating and cooling company for installs, repairs or maintenance.”

“Awesome company, awesome people”

“We had an amazing experience with Covenant Heating and Cooling! Calvin came out within an hour of our call, which was incredibly impressive and appreciated. From start to finish, he was professional, knowledgeable, and genuinely cared about making sure everything was working perfectly. It’s never easy—or something you want to deal with—having to replace a full furnace, but Calvin made the entire process feel like a walk in the park. He kept everything stress-free and handled it with such confidence and ease. He didn’t just fix the issue and leave—he stayed through the entire process, walked us through everything he was doing, and made sure we were completely set up before heading out. He even took the time to help get our new thermostat connected to WiFi and ensured we knew how to use it. It’s rare to find that level of service and attention to detail these days. We’re beyond grateful and would highly recommend Covenant Heating and Cooling—especially Calvin—to anyone needing reliable and thorough service!”

“Calvin was very quick to get out to my home and help me get my furnace going again. Very personable and quick to find the issue with affordable recommendations.”

“Just WOW! Calvin Peterson and his crew were amazing! He really took the time to listen to the issues we were having and then offered the solution. We had a new furnace and AC put in and they were all very professional, friendly and knowledgeable. We have a very old home with lots of unique wiring and Calvin and Caleb came again the next day and worked through some wiring issues causing the furnace not to work. They definitely went above and beyond to make sure we were taken care of. I would 100% recommend Calvin and his crew- Covenant Heating and cooling to anyone needing furnace/ac help! He knows his stuff!”

“Very professional, no pressure to buy from owner Calvin Peterson. Calvin is honest and will let you know what you may or may not need. Calvin’s employees are very professional, friendly & trustworthy to be in our home while we are not there. We are very impressed with the pricing, no one could beat the price we received. This is the first time that we have had a heat pump and we love it. It’s also an air conditioner. Call them for a free inspection. Local family owned business.”

“Really appreciate the owners great integrity”
