HVAC reviews in Mt Vernon, Missouri

Professional, detailed, and experienced.

Derick showed up ASAP and fixed our thermostat when we were having issues. They’re very professional and informative! I’d highly recommend them to anyone needing hvac services in the area!!

My ancient furnace stopped working during the negative temps. Sifferman heating and air came out on short notice and diagnosed the problem immediately. He was able to make the necessary repair, and assured us that even though the unit is old, it still has some life left in it now that it’s been repaired. Very thankful that he came out to help us keep our babies warm. We have 3 young children in the house, so we were panicking! Thanks for the quick and excellent work!

Last week on that cold morning we woke up to no heat called Jameson heating and air and one of their service techs was here before noon and discovered the issue. We called on them for another problem at my in laws house before selling it, they are a great company for your heating and air issues.

Brian and his staff are totally amazing. Back in November our furnace went out the day before Thanksgiving and I called Brian to ask him when and if he would be able to come out and replace the furnace. We had already talked to him about replacing the air conditioning unit this summer as well. He called me back and we discussed what we were looking for. He made a recommendation and 2 days later (the day after Thanksgiving) we had a new energy efficient furnace and air conditioning unit installed. His guys were here all day and were very polite and respectful and did an amazing job. We didn't have to worry about anything and they got the job done. Today they came out and checked the air conditioning unit before we started to use it to make sure it was all ready for this summer.
This team is top notch and I will never use anyone else. Thank you so much for taking the worries away and making getting a new furnace and air conditioning unit not a stressful decision.

We had a new heat pump installed last summer by another place in town, and it never worked right. The previous company came out 6 separate times, but could never fix it, instead breaking the furnace once.

Jameson came out, and within 5 minutes had diagnosed the issue. He quickly fixed the issue, and everything is working better than the day it was installed.

Jameson is professional, and knowledgeable, willing to explain what he was doing, and answer any questions I had for him. He will definitely be my only call in the future, and my only recommendation for anything HVAC!

Right on time and very quick had us back up and running

Guys I cannot speak highly enough! They had three trucks at one point just to get the job done faster. One of the men, helped me get a water jog off my dogs head. Yes he got his head stuck in it. I got him in the house and was freaking out and the amazing guy just carefully got his head out. Another guy named Gabriel was the nicest person!! He genuinely cared that he was in someone’s home and honestly he cleaned his mess so well we would have had no idea no one had been there. The three main guys were Gabriel, Charlie, and Darren and they were all so awesome. In terms of working fast, efficiency, and genuine kindness, these guys were the best! For any HVAC needs we choose Jameson Heating and Air!

Brian is great! He is quick to respond to calls/texts. You can tell he truly enjoys his job. His staff did an excellent job replacing my HVAC system. They were friendly and finished the job in a timely manner. I would recommend Jameson to anyone who asks!! Thanks again, Brain!

Came out the same day I called and had my AC fixed and running after replacing a part, great service and reasonable prices.

I called as a first time customer in the middle of a heat wave. Jameson not only came out the same day but had my problem fixed that afternoon! Very nice, professional, knowledgeable people! Highly recommend!

Brian and his staff were very knowledgeable and made my AC system work better than I could have ever imagined despite the constraints inherent to the old design of the building. I would definitely recommend their services.

As always excellent service. The technician was thorough. He fixed the problem but also made sure there were not any other issues with the unit. We love Jameson. We have been using them for couple of years now.

Jameson Heating and Air was the best thing since moving into a money pit we have done. Brian came by and gave us a detailed estimate to fix ALL issues we had going on; from a unit way too small, to the duct work that was needing to be replaced all together. Brian listened to all my concerns and assured he would take care of us. His crew was the most conscientious and took pride in their craftsmanship. Cleaned up everything and went through what was to be our new way of living, with a working HVAC. Please don’t think twice about dealing with Jameson, best decision ever!

We’ve had issues with our air for years, and every year another company comes out to “fix” the problem. However, when I reached out to Jameson Heating & Cooling, not only were they extremely prompt, but they fixed the issues and seemed to bend over backwards to fix all our issues. They worked SO well with our Homeowners Ins & were so sweet & helpful throughout the process. I would recommend them over & over to anyone who needs quality, prompt work done.

When our central air broke down, they were out that afternoon to look at it. It was quickly diagnosed and a plan to get it replaced was set up quickly! Good price was quoted (we got other estimates too) and all the employees were super nice and professional. I would highly recommend.

Replaced heat and air units with new. Great work and done ahead of schedule.

Jameson was recommended by a friend. They responded quickly and got our AC back up and running the same day, in the middle of a heatwave! The technician was friendly and knowledgable, and had suggestions for future preventative maintenance. Thank you!

They were very courteous, arrived on time, performed the work professionally. They cleaned up their work area and hauled the unit they replaced. Brian's price was reasonable and honest. His crew( Charlie, Shawn, and James) were great. I would definitely recommend their work and utilize their expertise in the future.

"Rocky from Jameson Heating & Air did a great job cleaning my HVAC system for the summer. He arrived right on time, was friendly and professional, and left everything clean. Really appreciate the quality service—highly recommend!"

This is a great company to do business with. They had a new system installed in one day and were super nice to work with. It's so nice to have a company that appreciates your business.
