"When my water heater died I called a bunch of places, and nobody could make it out until the following week. A friend at work recommended Mull Bros. I spoke to Tom, and within 30 minutes an expert was at my house putting in a new tank. They are so friendly and nice, and you can see they love their work. I would definitely hire them again."

"Precise HVAC was wonderful. I actually was going to get more quotes but after working with their salesperson I decided to not even bother. They answered all my questions and made suggestions for things I didn't know about. I'm not even sure I care if I got a better quote or not. With Precise I know that they cross the t's and dotted the eyes and I don't have to worry about missing something."

"Josh and his crew were amazing. I had an air handler that needed to be removed and a new one installed. Great price for removal and installation. It felt like they were done in no time! Highly recommend tandem mechanical. Out side central air condenser is next on my list and I will for sure have these guys back."

"Juan responded quickly on a Sunday afternoon. He was very knowledgeable and fixed the broken part. Fortunately, Juan had the part in his truck and was able to get my furnace working again. The service was impeccable! However, the weekend rates are expensive the service cost me $699 for installation of a $70 part. The 2-hour service call was $500 ($249 per hour)."

Install Boiler questions, answered by experts

It can take anywhere from four hours to three days to replace a boiler with a new one. How long your particular boiler installation takes will depend on whether you need a gas line installed and if you’re switching to a new boiler system. 

Replacing a combination boiler or standard boiler with the same system should only take four to six hours. Meanwhile, switching from a conventional boiler system to a combination boiler system could take a few days.

Installation costs range from $4,000 to $12,000, depending on unit size, efficiency rating, and labor.

Yes. In many cases, switching from an old furnace to a high-efficiency boiler can help you save money over time. You can also save money by switching from an electric boiler to a gas boiler, which costs much less compared to the energy bills an electric boil can create. Boilers are often (but not always) more efficient than furnaces, too. Then there are discounts, rebates, and incentives that can help you save on the initial costs.

Deciding whether or not to replace radiators with a different heating system depends on your personal preferences. Radiators can take longer to heat up than a central heating system, and they take up floor space. However, they can be very efficient at heating, and they keep rooms at a more comfortable humidity level in the winter than forced-air systems.

Some high-quality steam boilers come with 10-year warranties, but a well-installed, properly maintained model can last at least 20 to 25 years. Learning how to clean a boiler, getting an annual professional service, and keeping up with maintenance and repairs on your heating system are all important for getting the most out of your model.
