I have used Darnold & Lyons for more than 20 years for my HVAC needs. I have three systems for my home, and they service them twice a year to keep them in good condition. I have had both warranty and off warranty repairs, and replaced one unit entirely in 2022. The technicians are always knowledgeable, prompt, and thorough. The office staff also work with me to schedule regular maintenance and unexpected service calls. I highly recommend Darnold & Lyons. UPDATE: In June 2026 I added A/C in my garage. Beau came the next day, designed a ductless system for my needs, and gave me a very affordable quote the same afternoon. The 6-man crew was scheduled, and efficiently installed the system and cleaned up by 1 pm. It was a great experience and I am really happy with the equipment and the workmanship of the installers. And I have no worries about maintenance. They come twice annually to keep everything in top shape. I've also used Darnold & Lyons for my plumbing needs on numerous occassions and I am always pleased with their service. Whether it is a new installation or fixing some issue with an existing appliance, they are quick to schedule, arrive promptly as promised, and work quickly and accurately. They are my reliable go-to for plumbing.

Had a new HVAC system installed. Beau was great to work with from the Sales team and Randy along with this team provided excellent installation services. Highly recommend!

All the guys were nice and did the job beyond my expectations

I got very good air conditioning service from tech JR Bishop today

I called up on a Sunday night when my thermostat went out when it was very hot outside. They answered directly and professionally even though it was late, which I really appreciated. Then I met JR Bishop and his helper Baylen and let me tell you, They. Are. Awesome! They are well-trained and professional, and also really good guys. They took a lot of care in their work, explaining things and getting me the very best deal. I’ve used Darnold before because they’re so dependable, but JR and Baylen made me a customer for life!

Had my yearly maintenance cleaning and checking today. JR Bishop and his assistant are AWESOME. They were respectful, polite and knowledgeable. I've been with Darnold and Lyons for years and will continue to utilize them with all my HVAC.

Very happy with my experience with Darnold and Lyons. I scheduled an AC tuneup. The lady that helped me schedule the service was very friendly and accommodating. My technician was JR Bishop. He was polite and helpful. The unit inspection was thorough. Thanks, JR!

Have used DarnoldLyons for years and have always gotten great service. JR Bishop always does a very thorough and complete job on my maintenance visits! Appreciate him and the company!

I would highly recommend this company, they helped me fix my hvac after another company did not and left me with no air and a overcharged unit . Great customer service and my tech was friendly and was knowledgeable he knew what he was doing and took his time to try to get my problem fixed. They also called and did a follow up to make sure everything was still working. I will stay with this company in the future.

JR and Baylen did a wonderful job on my biannual inspection/service. JR is experienced, knowledgeable, reliable and trustworthy, as was his assistant Baylen. Can't say enough about how nice it is to deal with everyone at this company.

JR Bishop always does a great job for us. He is polite and very knowledgeable. His helper Baylen Herdsmen was also very polite and seemed to know what he was doing also. They both were very helpful. Darnold and Lyons team is always so nice to work with. We’ve been dealing with them for 14 years now and their technicians are always so good to deal with. JR is the best.

I had to place a service call after hours for an issue with my air conditioner. A technician named Adam called me back and we discussed what the problem was. Adam gave me an approximate time he would show up and he was right on time. The work was completed timely and got my unit back up and running. I would recommend Darnold Lyons to anyone needing AC/Heating services. Thank you!

Adam had the problem diagnosed within the first 10 minutes after arriving. And then went above and beyond to fix the problem. My AC unit literally performs better now than when new. Would definitely recommend.

I recently had a full HVAC installation done by DarnoldLyons. This is my first time working with them, and I've had a great experience so far. I especially appreciate Beau for being so responsive and helpful throughout the process, as well as French and his team for their professionalism and answering all my questions during the installation.

We had a great experience with JR and Ryan. They were timely, knowledgeable, and kept us informed throughout the entire appointment. We would definitely recommend!

Today was my first time using this company. Within minutes of filling out an online form requesting service they called and had a tech out within an hour. The tech, Adam, was everything you would want in a service tech. Very knowledgeable, professional, and got the job done quickly and for a reasonable charge. Adam has earned my business and I will definitely use this company in the future.

Adam came out the same day we called and asked about getting our unit check. He was on time and did a great job at explaining what was going on.

They are always prompt and easy to work with. J.R. has been servicing my units for years now and he is very efficient, very friendly, always gets the job done quickly! Would recommend Darnold And Lyons to anyone looking for a good solid reliable company.!!

The technician Adam was great did a good job
