One Hour Air Conditioning & Heating® of Harford County

"Very polite and efficient technician."

"Gilmer checked the furnace and air conditioning unit. He replaced two components in the furnace--a new flame sensor and new yellow pan treatment. He made two recommendations--duct cleaning and air filter sensor. He completed all work within an hour."

"Mr Rojas was on time, very efficient and proficient. He showed us where we needed to make some improvements, as far as duct cleaning is concerned, and walked us through everything that needed to be done to keep our system healthy. We've been using One Hour for quite a few years now and we have no complaints. If you're looking for a long-term company to service your needs, One Hour Heating and Air Conditioning is for you."

"Gilmer did a great job and was very helpful and explained everything he needed to do."

"Great job, very polite and knowledgeable. Thank you very much!"

"Rojas did a great job. He explained everything as he did the job. Was very through."

"A big help"
