"Dave (Dawson Mechanical) is awesome. He is the only plumbing company I use. His knowledge is on another level and he runs a great company. It is easy to get an appointment and he responds right away. You can feel confident, if you have an emergency or non-emergency situation you that can get touch with him. In the past he installed a new boiler, furnace and converted us over to gas from oil heat. The work he and the guys did on the furnace/boiler is so good that other contractors comment on it. It really is a work of art - very neat. Most recently, he helped fix a bad plumbing job a contractor did during a bathroom model. The bottom of the toilet was flooding and the shower made a gurgling noise every time the toilet was flushed - it was an annoying odd problem. John came over during the covid pandemic, analyzed the situation and came up with a solution. He wore gloves, a mask and maintained space between us. I am very impressed with his expertise and the level of detail and attention he works with. However, I shouldn’t have been surprised based on how great of a company Dawson Mechanical is. He hires quality technicians. Lesson learned - dont let the contractor do plumbing work. I will definitely use Dawson Mechanical again."

"7/30/19 contacted Home Advisor for a plumber referral because plumber we were using could not resolve the issue. Tom Brady called within five minutes of me submitting the inquiry. I forwarded information regarding the air switch error code, so he could research the issue for our condensing boiler. He followed up with NTIs Tech Support to fully understand the error code and possible solutions. We set up an appointment for 8/8 for him to assess the system. The first thing he did was check the air intake for obstruction and found a honeycomb nest. The previous plumber said there was no need to check the intake so never checked. He assessed the system, identified parts to be replaced, and set up an appointment to return to install parts and recharge the system with glycol anti-freeze which the previous plumber did not do. 8/21- Tom returned, installed parts, checked and adjusted the CO2 (which the previous plumber could not do because he did not have the tool), recharged the system, and advised our 15-year-old boiler was in good shape and did not need to be replaced. This was a relief given the previous plumber suggested it did need to be replaced. We are thrilled with Toms service and highly recommend him. He is thorough in his research and demonstrated he is a highly skilled plumber in analyzing/repairing our system. Since he completed the work we have on-demand hot water every time we called for it."

"I had such a great experience with Liv Air! They serviced my boiler, and from start to finish the process was seamless. Leo is incredibly professional, easy to speak with, and genuinely such a nice person. He?s honest, reliable, and you can tell he truly cares about his customers. The technician who came to replace the parts was also wonderful ? very clean, respectful, and efficient. I?ve dealt with other companies before, but no one even comes close to the level of service Liv Air provides. Their pricing is fair and reasonable, and they answer calls right away, which is so rare these days. I?m honestly taken back by how great they were. I highly recommend Liv Air!"

"Curt came out first to do an assessment, and did an amazing job. Thorough, professional, and exact. Then, 4 days later Chris, Phil, Jose, and Jorge came to do the demo of our old boiler and water heater, and install of the new ones. We could not possibly be happier with the results! They did an incredible job, the new pipework from both systems are beautiful, and most importantly, the heat in the house is perfect and evenly distributed. If you want perfection, hire Pipe Works. They are the best."

"One of Gold Medal service rep stopped by to assets the project. He was very knowledgable and informative. He explained the benefit of having this type of service done by a professional person. I immediately hired them to install the gas line for my dryer. Unfortunately, I could not complete the job due to family circumstances. The rep understood and was the job was canceled without any penalty."

Install Boiler questions, answered by experts

When winter rolls around, and you turn the heat on for the first time in a year, it’s normal to sense a light odor. This could smell a little like burning because some dust has gathered in the heating unit over the warm months and will fade away shortly after. However, there are some smells you should watch out for and take caution around: an egg-like sulfur smell or an electrical burn odor would indicate there’s something wrong. Turn it off and call a professional for maintenance as soon as possible. 

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.

Many utility companies and government programs offer rebates or incentives for the installation of high-efficiency propane boilers. These can offset upfront costs and improve your return on investment. Check with your local utility or installer for current offers. Incentives vary by state and provider, so exploring regional programs can help maximize your savings.

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.

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.
