"Kyle P. did all the water related services. Last year he installed a water softener tank and this year installed a sediment filter and UV tank as well as an arsenic treatment tank. He is always on time, explains work thoroughly, he's neat about his appearance and how he handles the work environment. Kyle is personable and pleasant.Highest recommendation. This company installed the ductless midi's in our home 3 years ago and in every aspect they are fantastic."

"The Daigle plumbing tech arrived on time, worked hard to diagnose the problem. There were a number of unusual issues that he worked through to make the repairs and he returned my boiler to good working order. The first HVAC companyI hired made repeated trips and was not able to correct the problem. Would definitely recommend Daigle Plumbing to others."

"Matthew responded very quickly to my call and showed up promptly thereafter. He was very professional and worked diligently to get my boiler working again and the heat restored to my home. He was able to diagnose the problem rather quickly and fixed the issue, even going so far as to explain many of the parts he had to replace and made me feel very comfortable that my unit was running efficiently when it was all done. I would highly recommend NexGen Aire and plan to call Matthew again for future issues. Fast, efficient, and affordable."

"They came when scheduled, did very careful job, attentive to details. The office scheduled the required plumbing and electrical inspections by my town (for new boiler) and that was efficiently handled too. The salesman who made the initial presentation was very informative and measured home carefully before making his recommondation. Very pleased with Heritage."

Install Boiler FAQs, answered by experts

The cost of heating oil fluctuates rapidly based on supply and demand, but the average price is between $4.00 and $4.50 per gallon, which means filling a standard 275-gallon tank would cost between $1,100 and $1,240. Much like automotive gasoline, the price of home heating oil changes constantly, so the only way to get an accurate and current price per gallon is to contact a heating oil delivery company. Some companies also offer contracts with a set price that should be an average cost over the contract term.

If you hear your radiator clanking even when it’s turned off, it’s typically because there’s trapped water or air in the system, causing a pressure buildup. When you hear significant clanking, popping, crackling, or banging in a radiator that’s turned off, you’ll want to bleed the pipes or call in an HVAC specialist to deal with the problem (and prevent it from happening in the future).

The most important sign of a boiler problem is something happening unexpectedly, which is why regular boiler maintenance is important. Unexpected problems can include strange smells, new leaks, and unexpected noises that your boiler wasn’t making before. Additionally, if a boiler keeps shutting off or can’t maintain a specific temperature range, it’s time to call in an expert.

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 range from $3,000 to $7,500, depending on system size and efficiency.
