"The owner, Steve, came out and explained everything and more that I should be aware of regarding the replacement of the 26 year old furnace and Air conditioning units. He was a pleasure to work with and the price quote was more than acceptable. I did accept and within the week the crew arrived to do the installation. Al and Damien were very professional and the work was extremely well done. They finished that same day and when they left it was if the new units had always been there. I was extremely impressed and will certainly go back to them for future maintenance. You can't go wrong with this company!"

"Porterhouse Heating and Cooling was very professional and knowledgeable on the service provided. I used them to install my air conditioner unit. Eventhough, the unit was not my issue, they still came out and was able to find the issue and fix it. They were friendly, professional, and reasonably priced. I will definitely use again for any of my HVAC concerns."

"Chose him due to the reviews and the price was right for my budget. The contractor who did the installation was good. Only thing I didn’t like was the fishing tactics like Mr Jackson was willing to upgrade the thermostat but after furnace was installed, nope. He said one I had was still good. Also the bullying to put in the reviews for the company. See that’s why he got 5 stars."

"Climate Master did a fantastic job servicing our furnace boiler for a seasonal tune-up. Chuck answered all my questions and offered helpful tips and explanation of how to properly care for the system. He was reassuring and explained that there were no problems when I wasn't sure if a sound I had been hearing meant something was wrong. Kimmie was pleasant and helpful when scheduling. Thanks, guys!!"

Install Boiler FAQs, answered by experts

It takes about five to 10 minutes for heat to reach a radiator, then about one hour until the radiator fully heats up a room. The exact duration depends on the size of the room and how far away the radiator is from the boiler heating system. Heating up an entire house could take up to two hours.

Steam boilers require flushing at least every six to 12 months to keep them operating effectively for as long as possible. Depending on your water quality and frequency of use, you might need to do this more frequently. The flushing process helps to remove problematic buildup of sediments. While a boiler contractor near you can perform a thorough annual flush, learning how to drain the system yourself means you can do this monthly if you experience speedy mineral accumulation because of hard water. 

Always consult your manual for specific pressure numbers. Many expansion tanks come pre-pressurized at a specific PSI range, anywhere from 12 to 40 PSI, designed for a range of home boilers. You should not have to pressurize an expansion tank yourself, only the boiler system. If your system has a tank that needs to be manually pressurized, this is generally a job for professionals and their tools.

A furnace is a big unit where gas, heating oil, or electricity heats the air. The warmed air is then pushed back out through ducts and vents. 

A boiler uses electricity, heating oil, or gas to heat water that is pushed into the room through a radiator. This is one of the oldest and most effective ways to heat a house, but radiators can also be unsightly and leave hot and cold spots in the room.

Heat pumps use a refrigerant to move heat from outside into the house and return it to the room through ducts and vents.

Costs depend on system size, efficiency rating, and additional features like zoning or smart controls.
