Featured Reviews for A/C Repair & HVAC Contractors in Gaithersburg

Air Duct Pros, Inc.
A/C Repair & HVAC Contractors in Gaithersburg
Average rating: 5 out of 5 starsJuly 24, 2013
“We purchased service with Air Ducts Pro as part of a promotional deal. They were very quick to schedule service, and showed up right in the middle of the designated arrival window. The cleaning of the ducts was very thorough - they cut holes in the main lines and hooked up their vacuum line that was run in to the house through a window in the basement, and dislodged the gunk in the supply and return lines with their powered, spinning brushes. They showed me before and after pictures of the return lines and let me look myself into the more accessible ones, and the amount of junk on the surfaces before cleaning was impressive - after cleaning it looked much better! The house smelled fresher too. Due to some signs of rust and what might have been mold, they recommended a disinfectant service, but didn't give me a hard sell or scare tactics on it - simply presented the options and let me choose for myself if I felt it was worthwhile. When they were finished they closed up all the holes and thoroughly cleaned up after themselves. All in all great service!”
Climate Pro Mechanical, LLC
A/C Repair & HVAC Contractors in Gaithersburg
Average rating: 5 out of 5 starsFebruary 9, 2017
“Climate Pro was a lifesaver last summer when our air conditioner broke five days before settlement on the sale of our home. The company with which we had a maintenance contract as well as the local gas and electric company could not replace for at least two weeks. Kevin Creel and Climate Pro installed a new air conditioning unit in three days. They were efficient and professional as well as performing the work at reasonable price.”
ecobeco
A/C Repair & HVAC Contractors in Gaithersburg
Average rating: 5 out of 5 starsAugust 14, 2016
“I am a professional organizer, and after helping a client prepare their home for sale, I recommended ecobeco to correct structural and plumbing issues in order to pass inspection. Kelly Vogan and his team took care of the repairs promptly and at a very reasonable rate with excellent service. The home sold, passed inspection and everyone was happy. I will definitely call ecobeco in the future!”

“Nice Home Services did a fantastic job from start to finish. The temperature in our home is the same on all 3 levels. We love it. No more hot and cold rooms. We replaced our oil furnace with a high efficient heat pump. The air cleaners have done an amazing job in removing the smell and dust. No more wheezing and sneezing and no more smelly ducts. Nice Home Services also completed the installation of our propane fireplace and repaired our attic fan. All is well and we are very satisfied with Nice Home Services.”

Average rating: 5 out of 5 starsSeptember 18, 2017
“Tolbard's was extremely professional. The owner, Tony, met with me to discuss installing two split units in my older (1910) home. He provided me with a timely and competitive bid. From the office people to the installation people, everyone was friendly, knowledgable, timely, and professional. I also had his service staff clean and service three older units in the house. I couldn't have been more pleased.”

What do HVAC contractors do? HVAC stands for heating, ventilation and air conditioning. An HVAC technician or contractor specializes in heating systems, air duct cleaning and repairs, insulation and air conditioning for your Gaithersburg, MD home and other homes.

When should you hire local HVAC companies?


Generally, Gaithersburg HVAC contractors or HVAC installers work with or run companies that repair or install heating systems and a/c services for homes.

Local air conditioning companies can help with a wide variety of air conditioning services, including both a/c installation and a/c repair. Air conditioning contractors, also known as a/c contractors, get extremely busy in the summer when temperatures are highest. For larger jobs, like installation, you might want to hire a/c installers during the off season like spring or fall. You should also try to do the same for heating services. Heating installers and heating contractors might be more available in the summer or fall for larger projects.

Ask HVAC contractors about these residential heating and cooling technologies:


  • Tankless hot-water pumps
  • Residential air cleaning devices
  • Ductless air circulation systems
  • A desiccant enhanced evaporative air conditioner system (for hot and humid climates)
  • Heat recovery systems (which cool the air and heat water with no extra energy use)
