"Everything done exactly right, on schedule (ahead of what I was expecting). AJB quoted a Columbia boiler, which cost a little more than the others, but I believe will be worth it. Worked almost 13 hours the first day and a couple more the next day to get the job done. Cleaned the area and ensured everything was operating properly."

"Had a 15 year old gas tankless water heater that wasn't firing up. Other guy was telling me it needed to be replaced and was looking at 4,000 dollar bill. Called A & C and Chris found it was a flue issue and fixed the leak. Haven't had a problem since. Very professional and trustworthy. Highly recommend these guys"

"Mr. Bamford is an amazing gem. We have hired him repeatedly for different projects, and he ALWAYS goes above and beyond. Whether it's working over 15 hours straight to make sure we had hot water for the next morning, pricing out all of the alternatives to get us the best deal, or just popping by when we call to check out the issue and see what it will take, his service is above any provider I've ever worked with. I highly recommend him, and am grateful for the excellent service he provides."

"I had a difficult time tracking down a responsive, reasonably priced plumber, even through Angies List. Aqua has been fantastic. They were responsive to my calls and questions. I inquired about just replacing my 40 year old boiler which was not working after a dusty mess of a basement demolition (in addition to other questions). They had the opportunity to steer me in that expensive direction, but they instead told me of the challenges the new boilers have, and to periodically have old trusty cleaned and serviced instead. She should be reliable if I do that. Honesty goes a long way with me, as does customer service. This company is a gem. Unfortunately, my house is a hot mess as a result of significant demolition in my basement, so I will be calling again for a different leaky pipe after I leave this review. I'm thankful I now know who to call for my plumbing needs."

"Yes Thomas did a fabulous job with the many tasks. Pressurization of the main water valve, pressurization of the hot water heater, repair of a bathroom pipe, installation of isolation valves, bath tub repair and following and checking everything was working properly. Thomas is very easy to work with. He is knowledgeable, efficient, respectful and extremely thorough."

Boiler Repair FAQs, 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.

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.

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.

A poorly maintained boiler can lead to serious issues like deadly carbon monoxide poisoning, so schedule regular maintenance services. Of course, it’s also a good idea to check your carbon monoxide detectors in your home to make sure they’re working properly. Moreover, when you forget to maintain your boiler, small problems can lead to something much more serious, which will cost you more money in the long run. Repairs average around $400, while a full replacement can total over $6,000.

It’s not customary to tip HVAC technicians, and most professionals won’t expect it. However, it’s a nice way of showing your appreciation for the work they do, especially if they come out in inclement weather or on a weekend or holiday to fix an emergency issue if your heat or AC goes out in extreme temperatures. A good tip would be between 10% to 20% of the total bill, depending on how above and beyond the tech goes for your repair and on the total cost of your HVAC repair or service. For something like a routine tune-up or scheduled maintenance, tips aren’t expected.
