Bernie Hartung & Associates

Bernie Hartung & Associates is always my go to for my HVAC needs. I’ve been using them for a number of years and they are always on-time, courteous and professional. I’ve recommended them to several and they all say the same. Thank YOU for recommending them, and they are AWESOME!

Excellent service! Prompt, very professional and I was notified and informed of cost before providing additional service. Called and gave me a definitive time when Matt would be at the destination. Matt is very friendly, personal, knowledgeable and professional. I will recommend. Thank you!

Matt has been maintaining and/or servicing our 4 HVAC units for our 1906 home for the past 23 years, and is excellent. He has made it a point to build up and retain institutional knowledge about particular issues or aspects of our home system that impact our heating/cooling -- which means he can provide us with the service we need more efficiently, and we can count on the service fixing the issue. We would never use anyone else.

Bernie Hartung & Associates are great to work with. They know their stuff and give it to you straight. They did a great job on installing a new indoor and outdoor unit at my rental house and I also had them replace a fan motor on my primary residence outdoor unit. Excellent Service and quality work.

This business came highly recommended to me, and I have to say that I was not disappointed. Their workers were punctual, polite, and professional. Although there were problems with my breaker box, they worked until it was corrected. They did an excellent job, and left everything as clean or cleaner than what they found it. I will always use this company for my HVAC needs.

I can not recommend this company enough. They went out of their way to rescue my little family. I found out the hard way, on a very cold day, that my furnace had been destroyed by a flooded crawl space. I was terrified and had no idea what to do. Mike had a team out there that very day and a new furnace installed within 3 days. In the middle of covid when things were impossible to get. Not only that but his team was very kind and extremely professional. You will not regret working with Hartung, they are one of the few family owned companies left that still care about the welfare of their clients!

Stop - seriously, call them. No one in the Lexington area compares.

We have used Bernie Hartung & Associates for over a decade across two homes. We also take advantage of their seasonal maintenance program. The team is prompt, polite, and knowledgeable with low turnover, resulting in a solid experience with the contractor EVERY TIME. We know what to expect without any surprising 'upsells' or scare tactics. Highly recommend (and wish they would share their business practices with others!).

Arrived a few minutes early and worked efficiently installing a brand new air handler and replacing rusted out ductwork. The installers were professional and courteous and took extra time to answer all my questions and explain the necessary maintenance to ensure my new air handler would last for many years. I highly recommend Bernie Hartung.

We called Bernie Hartung out for a repair, during which they discovered that our heat exchanger was damaged and leaking dangerous levels of CO. Based on the age of the furnace we decided it was a better investment to replace it. Mike was able to shift some things around get the team out the next morning to limit how long we were without heat. The work the team did was clean and professional. Talking with them it's clear they're craftsmen who take pride in doing it right. In my conversations with Mike it's also clear they care about the community and doing right by their customers. We will definitely continue doing business with Bernie Hartung and won't hesitate to recommend them to friends and family.

Tech was on time. He was a very personable young man. Informed us of his findings. Highly recommend this company.
