Technician ran late for 5:30PM appt. but arranged visit for following morning. Quickly determined problem and repaired external heat pump unit for under $100.
What a great company to work with. Everyone I dealt with was professional and courteous. I especially appreciated how quickly the work got done.

Read reviews prior to hiring. Everyone I was in contact with was polite. Service was prompt during business hours. Tech was very knowledgeable and gave a few tips to ensure system was running efficiently. Will hire again as needed.

Last night the low was 6 in Walkersville. When we woke up the heat pump had gone out. We called and they had a technician out within the hour. Then fixed and running within another hour! Thanks, Jason did a great job! Very professional!

We were very pleased with the service we got from Kris at Dave’s! He was thoughtful, courteous and knowledgeable. We will definitely call Dave’s for future service!
We had a Mitsubishi Ductless installed. Glen was great to work with. He came out to explain the system and make sure it would work for us. The system works great. Glen followed up to make sure we are happy. Dave’s also does our HVAC maintenance and have always been professional. Highly recommended.-Donna C., Adamstown, MD
Everything went very well today. Thank your guys for us and thank you for getting it scheduled so quickly.

Justin arrived on-time for the scheduled appointment. He thoroughly checked the inside and outside units and discovered there was a loose wire in the compressor unit that was causing the problem. He also checked my second unit to make sure it was functioning properly. I always will call on Dave’s Mechanical Services for all my Heating, Cooling and Plumbing repairs.

Thank you Dave, for a job well done installing a new heating and air conditioning system. We appreciated your competent and professional work. We would be happy to do business in the future and recommend your services to others.
Dave installed a complete gas furnace and air conditioning system in our new addition for a great price.
Dave, I know you are busy. I just wanted to let you know the job you and crew did is absolutely beautiful. I wish I had been there to watch. Thanks for the nice job.
I had an issue with our gas heating system Thursday night and wanted to get it repaired before the weekend. I put in a request through Thumbtack, and Dave’s replied back within the hour. Gave me a time for Friday at noon. Howard arrived on time, was able to diagnose the issue and was done within 30 minutes. Great service, work quality and professionalism!

You all have been great to work with. If I hear of anyone needing work done, I will give them your name.
-Vaughn T., Woodbine, MD
I was thrilled when he arrived on time and diagnosed the problem in 15 minutes. Called to confirm availability of part, picked it up and completed repair. Took the time to explain the problem and what my future options were. Very pleasant and knowledgeable. Definitely will use in the future.
-Jennie M.Y., Middletown, MD
Very honest. I was very happy with the service they provided.

Thank you so much for the quick and reliable service. All my friends on the street recommended you.
Yesterday I had my Spring preventive maintenance performed. Matthew arrived on time, and I wanted to let you know how thorough and informative his visit was. He looked over every part of our system, reviewed it with me, and pointed out some settings/features that I was not aware of. We had our new Lennox HVAC installed by your company 18 months ago, and this was our first spring checkup. I’m so pleased that I contracted with your company for installation, and for maintenance.
Kris came out today – not only was he on time – he was early and very knowledgeable not only about our current issue but was able to give us line of site To upcoming problems we would need to be ready to solve for . Love his forward thinking approach. Oh and he was very nice!
From the time we found our old unit had failed through selecting and installing the new unit I felt confident I was making a good decision. Dave’s Mechanical field service was prompt and professional. Glen was easy to work with and kept me informed each step of the way. After several weeks with the new unit I remain very happy with the experience.

They were prompt, efficient and willing to share with my husband any issues with the heating and air conditioning system…There were none. We have a two level system requiring them to use a ladder to access the 2nd level system….It was a small access but they were able to access and check the system. Service was excellent, effective and reasonably priced…Would recommend to others.
Installed a new Mitsubishi system for our basement. Fast, and reasonable price. Pleasant sales person and polite and efficient installer. Good work!
-Linda K., Taneytown, MD
Just a great company to deal with very quick and honest.
Dave repaired my air conditioning unit for a third of what Frederick Air quoted me for. Ac works again. Call him before you call one of the big companies.
Dave’s saved the day now three times for me, going above and beyond my expectations. I recommend them highly. Whether it is the office or the technicians, you can expect the highest level of service. It is refreshing to find the level of attention to detail they provide in a world where service diminishes every day.
-Janet J., Westminster, MD
Randy and Glen provided quick, competent service, providing a humidifier on short notice.
-John G., Frederick, MD
Response is fast, and found problem immediately. The issue was solved within an hour.
They were prompt, on time, fixed problem.
Very prompt response, immediately identified the problem and fixed it. Also described other problems, and instead of fixing it and charging us, recommended that we go back to the installer and ask for a repair free of charge, which is what happened. I would definitely use Dave’s services again.
Your guys were right there when we needed them.
Thanks for great overall service!
Dave’s Mechanical Services has been our #1 heating and cooling consultant since we moved to Frederick. They are very considerate, well priced, thorough and go the extra mile for their customers. We are very happy with all their work and give them a completely EXCELLENT endorsement!
