Called, set up an appointment and the service repairman came . His name was Dean. He called before he was to arrive, he knew exactly how to fix the issue. He gave me a hint on removing the filter. Told me to make rabbit ears on the filter with duck tape. That way I can pull the filter out. I told him I was disappointed the installers did not show me how to remove the filter. After all, I really was not thrilled that I had to have a service call. The best part of this review is that there wasn't any charge, he gave me a pound of hummingbird coffee , a fabulous tip on removing the filter and we shook hands. Very thankful for the rabbit ear tip, everyone should learn this! Very pleased with Hummingbird, the service repairman Dean and my pound of coffee. But the best part... no charge. THANK YOU HUMMINGBIRD! Thank you Sheila Marsh

He was very knowledgeable, answered all my questions, was very respectable & informed me to keep track on replacing my filters on my calendar. It definitely made sense for my filter was way to clogged to be doing it's work like it should. It now is on my calendar every 3 months to remind me. I have never been disappointed in having Angelo Chiodo for many years. When I called the clerk on the phone was quick to set up my appointment also. They are very trustworthy at a very fair price as well. My sincere thanks!!!

If you have a boiler furnace, do NOT hire Angelo Chiodo to do any work on it. They do not appear to…read morehave expertise with boilers. I had them do yearly servicing on the boiler for the last three years and then had them repair it in February - March 2026 when there was a problem with very low heat. The problem was not correctly addressed. At no time did they check to determine that most of the water had drained out of the boiler. They said I needed a new aquastat and replaced it but set it to 200 degrees (about 40 degrees higher than needed). When I had a technician from a company that knows how to service boilers look at it, the inside was very dirty (had not been getting regular cleaning, although I had paid for maintenance each fall). He discovered that the water had drained out, that it needed flushing, and has repaired the boiler.

Let me begin with this question: Has anyone else dealt with JR Comerford & Son ? Tom Brathen bought the business back in 2011. Tom sent out a guy out, lets call him " Tommy Christmas" to deliver & install a power vent on our oil burning furnace just before the holidays in Nov. 2019. If the rating squares were lumps of coal I'd give them five lumps, but they're gold stars, like in grade school, so they get one. Like they spelled their name right, put then just drew rockets & planes on the exam paper but never answered any of the questions. For starters, they put in the wrong power vent, one intended for a gas burning furnace and the furnace never worked properly after that. Year after year, like Father Christmas they kept coming back to fix this or repair that and never made an effort to honestly address the under-lying issue, they knew was the culprit but did nothing to correct. Tom stated at one point, "it was the only one we had & the other one was too expensive... ." They never even taped the flue-pipe seams so smoke was leaking into my parents house for years. It wasn't until I returned for a visit and notice that the smoke pouring from the chimney didn't mean the Vatican had chosen a new Pope, it was just the toxic fumes leaking from the furnace. Meanwhile, the furnace continued to malfunction. It took me five minutes of searching the internet to discover the unlicensed elves installed the wrong venting mechanism. FUN FACT: NY State doesn't require furnace technicians to be licensed. Seriously, look it up, anyway~ When I explained to Tom I discovered he installed the wrong vent he texted, "they're basically the same thing, I just altered the voltage to make the gas one work with your furnace." This statement reveals that he knew it was wrong, but did it anyway. I contacted the company who made the vent and they warned us to stop using the furnace immediately and wait until a certified service tech could make the necessary repairs. Two weeks went by in Dec. 2023 The qualified company sent a repair tech out and saw the electrical system had been dangerously altered, necessary parts were missing and the entire system had to be repaired. We paid over $2000. to fix a problem he created and when I demanded he reimburse me for the expensive repairs he hilariously offered me a $400. "credit" He eventually reimbursed me for the entire amount. In the end, I wouldn't trust these guys to watch my goldfish never mind work on a boiler that uses combustion, fuel oil & electricity in my house. In my opinion-Anyone who has had this clown posse' work on anything in your home should have a qualified technician come out and inspect their work. .

Since then I've been unable to get their attention. When I called for service I was told that they are busy and cannot schedule anything. This is in September! What HVAC company is too busy to make an appointment in September? This one. I've owned several homes and never had this problem. When I hired another company come out to service my 2nd furnace in the house since Oswego Mechanical was too busy, I was told it had not been cleaned in years. News to me since I hired Oswego Mechanical to clean it last fall when they put in the new furnace. I cannot recommend this company. Lucky for me, they are not the only one in town.
