Did you know that high-efficiency furnaces and boilers can approach 100% energy efficiency in converting their fuel source into heat? But a heat pump can break 300% energy efficiency by using its electricity to pull more heat from the air and transfer it to your home — even if it’s cold outside, there’s still heat to be found! But this only works if your heat pump is in good working condition.

Fantastic service! From the staff I spoke with the two service and installation technicians, all were very informative and professional. I highly recommend JM Mechanical Heating and Cooling. I plan to utilize their services in the future for my semi- annual HVAC check-up!

Sandy G.

I was impressed by their level of customer service, and they really care about customer satisfaction. The office staff are very friendly, and they follow-up to be sure everything went as expected, and really want to help if there were any issues. Brandon is exceptional, takes the time to explain what is going on and really seems to care about his customers. A+ experience.


The woman who answered the phone was very helpful and professional and she immediately gave me available times and fortunately Jason was able to come on site today, detect the problem and I ended up needing a brand new water heater after mine had been over 12 years old. Jason was incredibly professional, courteous, fast, and respectful of my home. I highly recommend JM to anyone and if I ever have trouble again they will be my FIRST call! Thank you for the exceptional service!!

Eva G.

Amazing service! Friendly is an understatement, they even entertained our German Shepherd by playing fetch with him. Very knowledgeable and efficient as well. You can tell they love their work and they know how to do it. Highly recommend!!

Crissy B.

Excellent service from administration to service. JM Mechanical conducts business in an honest and ethical manner at an affordable price. Service is also extremely timely. James H. has installed both a water heater and furnace at my home in the last 6 weeks. James is knowledgeable, professional, courteous, and a pleasure to do business with; I am very pleased with both jobs. Thank you JM Mechanical; I greatly appreciate your reliability, quality and integrity.

Brian L.

James H. and Jeff F. were prompt as per usual this morning and gave prior notification via text messaging that they were on their way. We have nothing but nice things to say about this company. They are always clear and concise on the course of action necessary to fix the problem. Every time we have used J.M. Mechanical we have been treated with the utmost respect and have never talked down to us like some other companies have done. They installed a new heat pump for us today and we couldn’t be happier with the results. They were fast and efficient in every way and we will continue to use them on any of our future needs.

Dennis M.

Always great customer service and incredibly fast service from JM Mechanical! Plus, their repairs and replacements for our apartment rentals have always been top notch. Myself and my family would gladly recommend them to anybody!

Brent B.

By far the best HVAC company that I have ever dealt with. Extremely professional and they do excellent work! I use them for both my home and business.
