Routine inspections also reduce the risk of major repairs by identifying problems early.
Another benefit of enrolling in a maintenance plan is the added convenience and peace of mind.

SO THANKFUL!! Tom saved my life….well, my sanity and the sanity of the 6 animals I’m currently petsitting. I walked in to the house I’m watching last night to hear that annoying double beep from what sounds like it should be a low battery on a fire alarm. Find a ladder and start climbing to the top of the highest ceilings ever and all the dogs start howling and singing thinking I’m in danger. As touching as it was, it was not helping. Every 30 seconds that the alarm went off so did the puppers. No matter where I went to check the alarms the sound was bouncing off the walls to a different area of the house. Even after I took all the batteries out the beeping continued and now after an hour what seemed like an even higher pitch. Took all 6 animals upstairs to the room I stay in so they would stop pacing and we all went to bed hoping the sound would magically be gone the next morning. Shocker, it wasn’t. My husband came over and tried for an hour and couldn’t figure it out. Finally I was referred to this company and Tom showed up shortly after I called. After a few baffling minutes he somehow pinpointed the area and crawled behind an entertainment center behind a wall and found a carbon monoxide detector that was the culprit. He made me feel better that I wasn’t crazy and the dogs were able to finally chill out downstairs. Rate was extremely reasonable seeing as other companies were trying to get a phone consult fee before even heading over. THANK YOU TOM!!! Gary Anderson2024-12-26Trustindex verifies that the original source of the review is Google.

Tom is always knowledgeable, honest, and reliable. You won’t spend money on things you don’t need. Liz French2024-12-12Trustindex verifies that the original source of the review is Google. I needed both an air conditioner and furnace replacement and this company was helpful, responsive and a pleasure to work with. I would highly recommend them! Ian, Becky & Nicole Browne2024-11-21Trustindex verifies that the original source of the review is Google. Tom was very thorough in explaining exactly what he was doing. Showing every step of the test to see if our furnace had a cracker heat exchanger. I learned so much good information, so that I'm more knowledgeable about our furnace. He's patient, kind, friendly and so helpful. Plus, he came out the same day he contacted me, which was wonderful. His assessment put our family at ease to use our furnace.
