Rob (owner) came out himself to investigate a call I made on Monday that our steam boiler was not…read moreworking properly, he accessed we'd need a new one and said it was corrode. Let's face it, spending that $ for the stuff you cannot see is never fun but Rob gave a good fair price. His techs - Mark and Robert -were here all day and did not stop until job was done, checking to make sure it was working properly and explaining the system to us so it can function for years to come. They were cordial in working in masks in this trying time (and with us wearing them in our home as well to protect them). Removing the old furnace was a task in itself as it easily weighed OVER 500 lbs and had to be broken up in two pieces to get out of our basement! I had used DB prior to for our annual AC checks, but this is the first big time job and couldn't be happier. Great service all the way around.

I have been recommending this company for years. Brian O'Neill is been in business for a long time…read moreand that means a lot. You have to be good at what you do to achieve longevity. As a real estate agent, I work with contractors all the time and recommend them to my buyers and sellers. I've never had one complaint in I'd say, close to 20 years. Last week was yet another example. A homeowner called me up for help. Her mom passed away and she was clearing out the house to get it ready for the market. It was a hot day and the central air suddenly quit. She's not local and didn't know who else to call because other contractors she'd been told to call were either unresponsive or seemed to be not all that forthright. The company who had been servicing the house forever seemed to be the worst - took a quick look and told her the entire unit needed to be replaced with a staggering bid amount. Of all the contractors who came, Brian was the only one who told her that she did not have to replace the entire unit. All she needed was 1 part. The cost difference on this? Tremendous. Please note that when she called Brian, she'd told him that an estimate for replacement was needed. While my client was surprised, I wasn't. I've heard stories like this about O'Neill Contractors before. My experience with them is that they do excellent work and are highly ethical. It's no wonder they've been in business for a long time.

They are reliable, responsive, and always there when you need them. A special thank you to Billy Farrell, who recently came out to repair the air conditioning system at my office. He quickly diagnosed the problem, explained everything clearly, and had it fixed in no time. His knowledge, professionalism, and attention to detail were outstanding. The personality, respect, and dedication that Tim and his team bring to their work speak volumes about why their company is so successful. It's refreshing to work with a company that genuinely cares about providing excellent service. If you're looking for an HVAC company you can trust, TEMCO is the one to call.

What sets TEMCO apart from others is the character of the ownership and management. The company…read morelooks out for the best interests of the consumer, and honors courtesy, fairness and fair dealing above all else. Case in point when a faulty heater was installed years ago by another outfit. The owner Tim documented the issues, and problem solving attempts, and was able to navigate a warranty replacement with the manufacturer, and provide a speedy installation of a new heater at a reasonable cost. It's comforting to do business with a company of high ethical character. I also admire a local company that invests in teaching and training local young talent so one day they can serve their communities with the same skill and adherence to the high standards of ethical responsibility of the current ownership.
