"I called Mehmet based on the Angie's list recommendation and the terrific reviews. Mehmet worked around my work schedule and came after 5. He identified the problem and installed a new capasitor. He was in and out of here in 30 mins. A week earlier a rip/off big company (Varsity) claimed the unit could not be fixed for under $3500 and recommended I install a whole new system for $11,000. Mehmet's skill, reasonable price and honesty were well appreciated here."

"Talk about Top Quality service! From the professionalism of Daniel, to the great job done by Humberto and Ernest. I couldn't have had a better experience in a bad situation. They replaced our steam boiler, and our water tank and did a wonderful job. We have a warm house again thanks to them! Humberto, Ernest, I take my hat off to you!"

"Very please with the install. Vin was very professional and applied due diligence to the project. His oversight and instruction provided the reinsurance that needed. I requested four heating and AC vendors to provide proposals. Tyler was most responsive to my questions and offered me alternatives along with helpful suggestions. My next project is my boiler. I will be turning them in the future."

"I called All Weather to give me a quote for replacing my gas boiler. They set up a time for their salesperson to come over and give me a quote. The appointment was only a few days later and a man named Joe showed up on time. He spent some time with me, I told him I was looking for a new boiler and a new hot water heater, but I wanted to see what options I have (since I was debating going to a tankless water heater). He told me going indirect hot water tank is the best option and they always use this brand that's the "best one out there". Even though he may have been right, he didn't tend to my questions or concerns very well. I felt like he was getting annoyed that I had questions and eventually I just let him run the show just to get him out of my house faster. Especially when he gave me a quote of $8600, it was much higher than I was anticipating. One thing I really didn't like was when he said I'd have to get a permit since I live in an incorporated village, which would be an extra $500, meanwhile I already had another plumber tell me a permits only $200. So I went with another company. So even though I can't rate All Weather on their work quality, I didn't get a good feeling from their salesperson."

"They were great! Even found a way of adding a 40 gallon water heater to a smaller space. Which has been wonderful! They worked in a VERY tight space and got the job done! I highly recommend them! Will be using them to install my central air as well!"

"They came out and gave an estimate for a new boiler and we contracted with them for the replacement. The technicians seemed very knowledgeable and thorough. We had a few issues after the installation with air getting in the line and blocking the flow of hot water. However, Our installation came with a 1 year service contract and they returned to remedy the problem promptly and professionally. Bell stands behind their work. We would recommend Bell and will use them in the future."

"I looked at over 10 different mini split installers over a year and had just about given up. It wasn't until I found Kelley's Heating & cooling. They were honest up front and worked directly with an electrician (who also did an amazing job!) to quote me the best price. Mariana in the office worked directly with me to ensure I got all the Energize CT rebates pre-approved and factored into my quote. By far there team was light years ahead of all the other installers I met with who didn't even include electrical. The fact that they are Fujitsu certified was also a big win in my book. I can't say enough positive things about the installation team. They were professional, clean, and organized. Within about 4 hours they had my new mini split wired in looking great and sounding super quiet. Would highly recommend this team."

Install Boiler questions, answered by experts

The radiators closest in proximity to the boiler heating system will heat up first. Radiators in rooms farther away from the boiler will take longer to heat up and may be the coolest rooms in the house. The radiator unit itself should heat up evenly; otherwise, there may be trapped air inside it.

The best way to compare HVAC quotes is getting a few detailed quotes from local companies with good reputations. Then, go over the quotes line by line. Protect yourself by insisting on in-person estimates that include equipment manufacturer names, model numbers, SEER ratings, amounts and numbers of materials, details of warranties on equipment and labor, and other specifics. 

Knowing the exact equipment and materials is the only way that you can fairly compare quotes. Quotes that are much lower than others can be a sign that the company isn’t providing the best quality service or materials.

Common problems include leaks, low pressure, and inefficient heating. Regular maintenance prevents many issues.

The average cost to replace or install a new HVAC system is around $7,500. However, the price can range from $5,000 to $12,500, depending on factors like the size of your home, the type and brand of the unit, and your specific heating and cooling needs. If you only need to replace certain components, the cost will be lower; for example, a new AC unit can cost between $2,200 and $5,500, while a new furnace costs $3,200 to $6,000. If additional work like new ductwork is required, the total cost could be as high as $22,000. It's best to contact a local HVAC company for an accurate quote.

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.
