"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!"

"Prompt service with very little advanced notice. Technician removed old flame sensor and installed a new one in about 20 minutes. Pleased with technician and service, and will do business again them again if needed. Owner called to confirm service and sent a text with name and information about the technician before his arrival."

"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."

Install Boiler FAQs, answered by experts

Safety concerns with propane boilers include proper venting to prevent carbon monoxide buildup, secure gas line connections, and regular inspection of safety controls. Professional boiler installation and annual maintenance are essential to minimize risks. Having a carbon monoxide detector installed in your home is essential for early detection of any leaks or ventilation issues.

The average lifespan of a boiler is typically between 15 and 20 years, though some may last for as little as 10 years while others can reach 30. A boiler's longevity is influenced by several factors, including the quality of the unit, proper installation, and consistent professional maintenance.

The material also plays a significant role. Older boilers made from durable cast iron can last for over 20 years, with some functioning for up to 50 years. However, it's important to consider their lower efficiency, which can lead to higher utility bills. Modern boilers, often made from steel alloys, are designed to withstand high pressure and temperatures and have an average lifespan of about 20 years.

To maximize your boiler's lifespan, ensure it is installed correctly, have it professionally maintained each year, and address any necessary repairs immediately.

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.

Professional HVAC installation requires licensed expertise in several areas, including electrical- and plumbing-related work. An HVAC team must know how to safely handle regulated refrigerant chemicals and the gas, oil, or propane used in furnaces and boilers. A proper HVAC installation protects your home from energy loss, fires, and even carbon monoxide leaks.

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.
