"They came quickly to assess my situation and provided an estimate on the spot, in writing. When I had a follow up question, they returned to see my existing boiler again. On the date selected for installation, their people arrived on-time and were organized and polite. Their price was comparable to the other quote I received, but I feel their service was better than the other company."

"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!"

"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."

"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."

"We hired thurston to power wash our house. The job took about 3 hours. They did a fantastic job! They power washed and scrubbed the house deck and even the driveway and sidewalk as well as the roof. Their attention to detail was outstanding! The siding looked like new, the deck was spotless , just a great job. Based on their work power washing our house I would definitely not only recommend them to power wash your house but I highly recommend them to do other jobs which I intend to do. This company definitely cares about delivering quality work to their customers. job title was not available in list so it was just chosen randomly. Actual job was power washing."

Install Boiler FAQs, answered by experts

Most experts recommend getting three to five HVAC quotes from licensed, insured, reputable local heating and cooling companies. Getting multiple detailed HVAC quotes (but not too many) lets you compare the equipment, services, and prices of several contractors without being overwhelmed by options. It can also let you see if one contractor’s prices are much higher or lower than the others and give you a chance to ask for clarification. That way, you can weed out any contractors who aren’t providing quality services or materials and find the company that best meets your budget, quality requirements, and long-term goals.

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.

Generally, an oil furnace is considered safer than a gas furnace for several reasons. While both types of furnaces can produce carbon monoxide, a leak in an oil furnace is easier to detect due to the smell. Oil furnaces also don't connect to a gas pipeline, which reduces the chance of a fuel leak. Most importantly, heating oil is not combustible, whereas natural gas is highly flammable. This means there is a much lower risk of combustion or explosion with an oil furnace. However, an oil furnace can still pose a fire hazard if it tips over.

The average lifespan of a boiler is typically between 15 and 20 years, though some may last for as little as 10 years while others can reach 30. A boiler's longevity is influenced by several factors, including the quality of the unit, proper installation, and consistent professional maintenance.

The material also plays a significant role. Older boilers made from durable cast iron can last for over 20 years, with some functioning for up to 50 years. However, it's important to consider their lower efficiency, which can lead to higher utility bills. Modern boilers, often made from steel alloys, are designed to withstand high pressure and temperatures and have an average lifespan of about 20 years.

To maximize your boiler's lifespan, ensure it is installed correctly, have it professionally maintained each year, and address any necessary repairs immediately.

You can save money on heating oil through a combination of improving home efficiency and smart purchasing strategies.

Home Efficiency and Usage:

  • Improve Insulation: Ensure your home, especially the basement and attic, is well-insulated and sealed against drafts to prevent heat leakage.

  • Manage Your Thermostat: Use a properly calibrated and programmable thermostat. Lower the temperature by a few degrees, particularly when you are away from home or asleep.

Purchasing Strategies:

  • Buy in the Off-Season: Order heating oil during the summer months when prices are generally at their lowest. This strategy is most effective if you have a large primary tank or a separate storage tank to accommodate bulk deliveries.

  • Consider a Delivery Contract: Some companies offer contracts with a set price for the term. This can lead to savings if market prices for oil increase, but you might pay more if prices drop.
