Featured Reviews for Air Conditioning and Heating Companies in Baltimore
A.J. Michaels
Air Conditioning and Heating Companies in Baltimore
"Our HVAC died in the middle of a brutal heat wave and AJ Michaels Salespeople came promptly, set up the replacement with courtes. They were not pushy at all, and seemed honest. The replacement unit was available quickly and the employee who installed it did a fine job, was very thorough. Everyone had very good customer service skills."

"I could not have been more impressed with Glenn! He installed both my new air conditioner and gas heater in 2015. Very knowledgeable, professional, and patient. He explained everything from beginning to end. I highly recommend him! You won't be disappointed!"

Air Duct Pros, Inc.
Air Conditioning and Heating Companies in Baltimore
"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!"

The Best Air Quality and Restoration
Air Conditioning and Heating Companies in Baltimore
"My home was affected by the Tubbs fire. We hired The Best Air Quality and Restoration to do a major cleanup effort in our home. Val and his team showed up and took care of everything. Their communication with me was outstanding. I always knew the plan for the day and they would call or text with any questions. Not only that they worked in tough conditions. Due to the fire there was no heat or water in the house. They never let the bad conditions affect their job. They always arrived and left with the best attitudes. I felt so lucky to have these ladies helping me get my home back together. I highly recommend this company and their employees are the best."

Climate Pro Mechanical, LLC
Air Conditioning and Heating Companies in Baltimore
"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."

"Steve Heidler and his team have done plumbing work for us for several years, so when we needed a bathroom remodel we turned to him. He came up with two great designs, and referred us to great sources for the tile, cabinet, shower doors, etc. Start to finish a great job, done quickly and well. Very neat workers, always prompt and hard-working."

No frost air conditioning & heating
Air Conditioning and Heating Companies in Baltimore
"Great folks. Experts in the field. Don't sell you a story, scare tactics or any kind of pressure. I chose them over 5 other quotes and we are very pleased. Didn't try to oversell me a unit. Installation was fast and they even allowed me to donate my previous 3 year old furnace (came with the house) to a person who called them asking for help with their old furnace. Will be using them for all of my cooling/heating needs."
