A Double Furnace Maintenance


When Herb needed not one, but both of his furnaces maintained before the cold winter season kicked in, he decided to reach out to us.


The very next day, we sent one of our technicians to take a look at Herb's furnaces and make any necessary tune-ups and small fixes. Upon entering Herb's home, our tech covered his shoes to protect the floor and began assessing Herb's systems. After making a few small adjustments to ensure the systems would run efficiently throughout the winter, our tech showed Herb how to replace his furnace filters. He also and wrote down the correct size of filter so Herb knew exactly which kind to buy. After explaining all of the adjustments he had made to the systems, our tech provided Herb with his business card and left Herb with 2 expertly maintained furnaces.

"I called to have winter checks on my two furnaces. The company scheduled me for the next business day, the technician arrived on time, was polite and efficient. The technician also covered his shoes to protect my interior. I'm one of those people who like to leave the outdoors out. The technician showed me how to replace the filters as well as writing down the size for each furnace. He gave me his card should I have any issues and was on his way."

I highly recommend his services...

"Jake, the technician, came to my house on time with a curtsy call an hour before. He was extremely knowledgeable and helped me solve my hot water heater issues. He was able to repair the issues and informed me of future issues that may occur. I will call Jake first with all of my HVAC and water heater issues in the future. I highly recommend his services as he is really professional and good guy in general."
