I called home comfort to fix my exhaust on my boiler. They showed up and recommended me to replace my unit. I only could afford them to fix my exhaust. They did their " maintenance" and told me they would call me when the parts come in. I called them 2 days later to check if they knew when parts would be. They said they would have their tech call me. I was never called. I called another 2 days later and they said they would check and calle back. They never called again. I called them 2 weeks later to see what going on. They told me they would check on my parts. I told them not to bother I already called a company called " the Mechanical Guy" they did cheaper and had parts on hand. I asked them why their tech would forge my signature on the check list saying what was done that day. They couldn't give me an answer and said they did nothing wrong. Their tech before he left told me there was zero carbon dioxide coming from my unit. Even with the holes in the exhaust. The Mechanical Guy informed me there was CO2 coming from my unit. Don't use Home Comfort Experts. All they want to do is sell you something new. If you don't bite on their sales pitch they will ghost you. You think they will come fix your furnace or ac bot they never call you again.
