Carlos came to check out our furnace that was acting strange. He checked the furnace thoroughly and discovered a couple things out of order. The vent was loose and sensor was built up. Carlos is very knowledgeable and easy to talk to.

Last night (Friday, Jan. 2, 2026.) at about 9 pm, my relatively new Lennox gas furnace (about 5 years old) suddenly stopped working. I then immediately called A1 Chesney and a lady answered my phone call. After I explained my furnace problem to her, she right away told me that she will send a technician to my house as early as possible in the morning on the following day (i. e. Saturday, Jan. 3, 2026. ). At around 9:30 am on Jan. 3 (Saturday), A1 Chesney’s technician Carlos arrived at my house. After spending about 1/2 hour to do a detail diagnosis on my furnace, he professionally & accurately determined the root cause of the problem with my relatively new Lennox furnace. He found out that the air inlet at the “Fresh Air Supply Pipe” that is located on the exterior wall of my house, which supplies “combustion air” to my furnace, was totally plugged up with snow & icicles. This therefore had caused the furnace not to be able to suck in the outside air to supply fresh air for its gas burner to burn the natural gas (i. e. the furnace was basically “suffocated”). After Carlos had thoroughly removed all the snow & icicles from the “air intake hole” at the bottom of the exterior “Fresh Air Supply Pipe” that supplies combustion air to the furnace, my furnace now has started to run again perfectly & also runs very smoothly. I want to thank Carlos for his very quick & prompt “service response”, very good & friendly customer service, and also his expertise & professionalism in quickly & accurately fixing my furnace problem, so that my house can now resume to have heat supply again so quickly in this rather cold weather conditions (about - 15 C). I also want to thank the lady at A1 Chesney who answered my “emergency phone call” last night. She was very helpful & cooperative, and also understood that my furnace problem was an urgent issue in such a cold weather condition. So she made sure that her technician Carlos will come to my house as early as possible in this morning. As a side note : The relatively new furnace & tankless hot water heater inside my house were supplied & installed by A1 Chesney about 5 years ago. This whole installation was very professionally & also very well done.
