"Boiler wasn't lighting on one of the coldest days of the year. The Tech from Vitt showed up that very day and quickly diagnosed a bad Spark Ignition Module. He replaced it and we had heat again. I would hire them again."

"Jeremiah was on time and he tried fixing the leaky toilet first. when that didn't work, he replaced the toilet with a new one (pre-purchased by me) and additionally installed a water bidet that I had purchased eariler as well. He offered to dump the old toilet for a fee which I availed and was overall a positive experience. Looking to hire him to do additional plumbing and furnace related work in the future.

"oven would shut off at high temps and door would lock. first visit reset controls to factory settings thinking power outages caused problem, service call fee only. Tried oven next day same problem as before. Called and they were out the next day. Diagnostics check revealed control panel was bad. Prepaid for order of new control panel. New panel was received and installed within 5 days with no additional service fees. Oven now works normal."

"Our AC stopped working the day before Father's Day. Jeramy came out, not only on a Sunday, but Father's Day! He quickly realized out AC had a freon leak. He quickly fixed the leak and added freon. He was in and out in a very timely manner! He did not charge us for a service call, even though it was a weekend! We would definitely use Jeramy again and recommend him to anyone!"

Install Boiler questions, answered by experts

The cost to install a steam boiler varies depending on the type, fuel used, and your house size. The average cost to install a boiler is $5,900. You could spend $2,000 for a basic electrical steam boiler or up to $9,000 for a high-efficiency oil-burning steam boiler. Boiler installation is a job that’s best left for professionals to complete, and, in some states, only licensed installers can legally complete the job.

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.

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

An HVAC system typically lasts between 10 and 30 years, with an average lifespan of 15 to 25 years. The longevity of the system is influenced by factors such as the quality of the unit, usage frequency, local climate, and how well it is maintained. Regular maintenance, including cleaning, filter replacements, and professional inspections, can help maximize its lifespan. Different components within the system have varying life expectancies. For example:

  • Furnaces: 15 to 30 years

  • Boilers: 20 to 35 years

  • Air Conditioners (AC units): 12 to 20 years

  • Heat Pumps: 10 to 20 years

  • Ductless Mini-Splits: 10 to 30 years

A common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn’t very accurate, and a dedicated pro wouldn’t use it for your home. If you talk to a pro who won’t or can’t perform a proper Manual J calculation, consider hiring someone more thorough.
