"We had a new high efficiency water heater installed to replace an aging system. Can't even begin to express how impressed we were with both the technician and the amazing work that was done. The technician was extremely professional and courteous and the end result exceeded our experience. We highly recommend ACE Home Services for any heating, cooling or plumbing work!"

"Great! Keith, Bunnie and their team are professional, pleasant and knowledgeable. They communicate, they are on time, they work cleanly and go the extra mile for service questions. They do not rush and Keith makes certain the customer is pleased with the progress and workmanship. In the Fall 2021, I had the heater replaced and just this past month, 2022 I had AIRCO return to do the air conditioning installation. I own an older home and it required a little extra TLC which Keith planned for and made adjustments as needed. I highly recommend them for any services ...."

"Fantastic contractor. Scott came to my house to provide estimate for furnace installation. Except for the fact that I decided on different approach, Scott would have been my #1 choice. He was over-the-top thorough and comprehensive in inpecting oil furnace, provided detailed and comprehensive information on options, was honest and candid in his assessment. Told me what was necessary and what was optional, not trying to sell me on what he wanted to sell. He also had excellent pricing. Bottomline, he is one of the best contractors I've ever met."

"Extremely honest. Rob (the Boiler Technician) analyzed my 41 year old boiler and showed me why it was having problems. He then stopped working on it and put the boiler back together and charged me $90.00 instead of the $180.00 he quoted me. Never had anyone do that in all my years. Just extremely honest and competent."

"Install action went fine but after the installer left we had problems with water pressure. It turned out that the manufacturer installed tubes in the heater where the water goes in and comes out restricting the flow. The technician found this and once removed we had our water pressure back. Although it took two days to resolve, the technician stayed on top of it and made sure the heater worked to our satisfaction.

"We requested service for our heat and a/c since it seemed to have a problem. The technician located the issue in a very short time and informed us that a new blower/fan needed to be ordered. After one week and not hearing anything from them I called and was informed that they would check and call back that day. After not hearing from them, I called again the next day and was finally told that the service was scheduled. The same technician came and installed the part, serviced the furnace and a/c. The total cost was nearly $100.00 less than originally estimated. 5 stars for the work that was done, but customer service response downgraded the overall score. Still HIGHLY RECOMMENDED​."

Install Boiler FAQs, answered by experts

If you have a closed-system boiler that requires an expansion tank, you cannot safely operate it without one, as this risks extensive damage or even explosions. You must find a way to make room for the installation. Options include repositioning the boiler, rerouting the boiler piping to a more open area, or performing minor remodeling to create the necessary space. If you are unsure whether your boiler needs an expansion tank or how to best accommodate one, it's recommended to have a local heating service professional assess the situation. They can confirm the requirement and suggest the most practical solution.

Chilled water HVAC systems use water instead of traditional components and refrigerants. They're more common in commercial settings than residential ones but are slowly being adopted by some homebuilders to cool homes. As the name implies, the system keeps the water chilled at 40 degrees and circulates it through water coils. The water absorbs the heat from your home and drains outdoors. Condo apartments are more likely to have chilled water HVAC than single-family homes because this system is designed to cool several rooms or large areas individually.

The best time to buy home heating oil is in the summer when the demand is lowest, as the prices are usually lower. However, waiting until the summer to buy is often unavoidable unless you install a separate storage tank. If you have the space for a second tank, you can expect to pay between $1,000 and $4,000 for the oil tank replacement or installation, depending on the capacity and location. You could quickly recuperate these costs, though, by stocking up on heating oil in the summer and avoiding deliveries in the winter when prices are highest.

Costs depend on unit size, labor, fuel type, and whether additional piping or venting is needed.

If you want a new boiler that’s going to help lower your fuel bills, you should buy one that has a high energy-efficiency rating. For example, a boiler that is rated “A” uses at least 90% of the energy created by the boiler. And in order to enjoy the best performance, it’s important to have it installed properly by a highly-rated tech.
