"Mull Brothers gave us an estimate on installation of central air conditioner in our old home.  Their price was slightly higher than some competitors (although not by very much), so we didn't end up using them.  However, I was very impressed with Mr. Mull's visit.  He was knowledgeable and thorough, and gave me great information without using any high-pressure sales tactics.  I will probably contact them again in the future for my next project.

"HARP sent a rep to the house, he did the evaluation for sizing, which was in line with the sizing tools I used. The solution he offered was just about what I had picked out, and I went with his recommendation. The install went fine. They did have to be reminded to retape some ducts, but we're happy to take care of it."

"great. Jesse was super smart, friendly, conscientious and knowledgable. he spotted a few things the previous tech didnt (including inefficiencies which were likely costing us money in propane costs). our boiler was super dirty and he got it looking and working as good as new (better actually as it wasn't set up correctly by the original home owner!). he put our mind at ease with his clear articulate explanation of what was needed and how he solved the problem. hopefully we get jesse again for next year's service. looking forward to a warm, cozy, efficient home this winter. thank you Jesse and Beacon!"

Install Boiler questions, answered by experts

Most home boilers will need an expansion tank. That’s because these boilers are closed-loop systems, where the water is trapped. An expansion tank is needed when the boiler heats the water and it expands, allowing air to condense in the tank to make room for the water. Other types of boilers don’t use an expansion tank, such as traditional steam boilers, but these aren’t as common. And hot water tanks may be able to use a pressure release valve instead. When in doubt, call in a pro to take a look.

Coolant and antifreeze are technically not the same thing. The difference between the two is the ratio of water to other chemicals. True antifreeze is mainly made up of either ethylene glycol or propylene glycol, while coolant comprises one part antifreeze and one part water. However, the terms coolant and antifreeze are often used interchangeably, even by pros.

Using heating oil to heat your home has its advantages, but it also has its disadvantages. 

Consider these drawbacks before installing a heating oil system:

  • Heating oil prices fluctuate frequently

  • Risk of oil spills or leaks

  • Produces more air pollution and soot compared to a gas furnace

  • Regular maintenance required for equipment

  • Need to reorder heating oil consistently to avoid running out

Yes. Boilers need water to run without overheating, also known as dry firing. If you run it without a sufficient volume of water, either because of a burst pipe or a leak, you run the risk of damaging your machine or jeopardizing the safety of your home as a whole. When in doubt, shut off your boiler and repair any plumbing issues before turning it back on. Alternatively, consider installing a low-water cutoff (LWCO) before any issues arise. This gadget will protect your boiler by monitoring water levels and automatically shutting it off if it gets too low. 

No, boilers and water heaters are not interchangeable because they serve different primary functions. Boilers are used for central heating systems, providing hot water or steam to heat your home. In contrast, a water heater's purpose is to supply hot water for daily household use, such as for faucets and showers. A water heater alone cannot supply the warm water or steam needed for a central heating system.

While they are not interchangeable, it is common to have both a boiler and a water heater. In fact, a conventional boiler often works best when a water heater system is already in place. The two systems can be combined to provide both heating and hot water, either by pairing a boiler with an indirect water heater or by installing a premade combination boiler-water heater unit. For home heating, some homeowners may also opt for a furnace instead of a boiler.
