"From start to finish it was a very positive experience. Shane explained everything and answered all my questions when he came out to give me an estimate on the project. Brandon and Brian showed up on time, completed the job in a timely manner and cleaned everything up when they were done. They showed me how to operate my new mini split AC system before they left. Shana was also very helpful when I called the office. The project turned out great. I would highly recommend Onofreo Home Comfort Systems."

"The technician showed up as scheduled. I thought I was hiring a "local" contractor but he said he had driven 2 hours to arrive to my job site. The work was done satisfactorily for what could be seen as inspecting all the duct work was not practical."

"Tom Mull talked to me on the phone and told me there was a 60% chance that he could fix it cheap. Then Mr. Mull came out and looked at it in person and told me that there was a cheap fix, and that there was a 50% chance that this would fix the problem for a while, so I told him to go ahead. Unfortunately, when his service tech came out to look at the oil tank, he told me there was a 0% chance that he could fix it cheap and that I needed a new oil tank. I did wind up getting a new oil tank, but not from Mull Brothers."

Air Conditioning questions, answered by experts

You should get anywhere from three to five quotes for HVAC replacement to get an idea of the average cost of a new unit. Although this quote-collecting process can be time consuming, it allows you to compare what work is required, what type of unit you should install, and how much you should expect to pay for the service.

It depends on the size of the space you’re cooling down. If you’re looking for the most affordable way to cool an entire house over a long period of time, then central air will be more cost-effective. But when it comes to cooling down a couple of rooms or one floor, a window unit may be the cheaper option, with both a lower cost to install and less energy used to run.

The best way to save money on HVAC repairs is by regularly having your system inspected and maintained. This can prevent bigger problems and costly repairs and replacements in the future. It’s also smart to buy quality equipment and hire companies that provide warranties on equipment and labor. If you need repairs, you may be able to save money by cashing in on rebates and incentives or keeping the area around your HVAC unit clear to shorten the time your contractor needs to spend in your home.

If your home has an existing forced-air heat system, you can add a central air conditioner to it. An HVAC technician can retrofit your forced-air heating system by installing an evaporator coil onto the furnace plenum, the box next to the furnace that draws in air. Once installed, the air conditioning coils use the furnace’s blower to circulate the air.

At a minimum, an HVAC system should be serviced once per year. However, a twice-a-year service schedule—once in the spring for the cooling system and once in the fall for the heating system—is often recommended, especially for older systems, heat pumps, or in climates with extreme temperatures. Regular service, which includes inspection, cleaning, and maintenance, ensures the system runs efficiently, helps prevent costly breakdowns during peak seasons, and can extend the unit's lifespan. You can also schedule a service if you notice issues like poor performance or strange noises.
