Heating & Air Conditioning / HVAC near Street

“Called Excel yesterday evening for Air conditioning not working with a high of 94 the next day. Bruce came out first thing the next morning and had the AC up and running in no time. Great customer service with prompt service.“

“I have a geothermal heat pump system Installed by Groundloop almost 14 years ago ! I love it. Super efficient and quiet. No noisy compressor in the yard to get rained and snowed on. It’s still running great. Had one “emergency” where a capacitor on the blower motor stopped, which they fixed quickly. Otherwise it’s just been routine cleaning and checkups. They always show up on time and show me what they are doing. Very professional and friendly. Hope this system lasts some more years, but I’ll have no doubts about getting them to do the replacement when the time comes.“

“Residential AC work in Bel Air- We noticed our AC was not working on a Friday night. We went outside and saw that the fan to the unit was not spinning and it was making a humming noise. We turned everything off and called at 7:30am on Saturday morning. The on-call technician, Mike B., contacted us and said it sounded like the capacitor. He was upfront with pricing for an emergency response versus scheduling a service appointment. We opted for the emergency response. We received a text when he was on the way and he was at our house by 10am. The AC was working by 1030am, just in time for the heat. Mike B. was extremely professional, informative, and upfront with pricing. Highly recommend using First Response Heating and Cooling if you are in Harford County. Thank you!!“

“Bought a house late last year and had Blevins out to work on my gas furnace over the winter then my HVAC this spring. They are prompt, courteous and prices are reasonable. Jake is very knowledgeable and efficient and answered all my questions. Will continue to use them for all my HVAC needs.“

“Carrington’s installed a new furnace and water heater 6 years ago and have been excellent to work with. A neighbors HVAC company accidentally cut our lines and Carrington’s made two trips to help us free of charge. Service like this is hard to find.

I’m a customer for life!“

“Krause Companies provides many services besides heating and air conditioning. We contracted them to complete a bathroom install. The work took a little longer than anticipated but they were gracious and understanding when we made changes. They are friendly and hard working. I would recommend them for any of your construction needs.“

“Mullhausen Heating and Air is the only one I will call. Work is always first-rate. Honesty is the policy at Mullhausen; you are given a direct diagnosis and preventative maintenance tips. Yesterday my mother-in-law's AC/Furnace quit working during 90 degree weather with projected 100's heat indexes coming in the next few days. We thought it was out of freon. Called on Saturday around twelve-thirty, Wayne was on-site within a few hours. It was not the freon; he diagnosed the correct problem and fixed it quickly. He carries every part for her system in his truck which eliminated any need for ordering a part. New parts weren't needed, but knowing he had everything was a comfort. My mother-in-law met Wayne yesterday and was so impressed by him that she's booking him to do her furnace maintenance in the fall.

Wayne came through for us multiple times, and has replaced entire my system previously. He taught me and my husband important information because he believes knowing what to do and how to prevent problems is better overall. He believes in doing a good job. I will always call Mullhausen and I will refer everyone to him. I am impressed every time with the job knowledge, honesty, responsiveness, and quality of work. Peace of mind is important and Wayne provides that.

Thank you for all that you do!“
