"I have used the company many times. Two technicians came out for the tuneup and completed the job in about 2 hours. The company has also replaced the furnace and AC in the past. They are very thorough and professional. The staff is also very friendly and available for service. I am a member of their club which makes them easily accessible to me."

"American Appliance Service was wonderful - extremely responsive, communicative, on-time, polite, knowledgeable, etc. Highly recommend. Our serviceman was Vic (I think he's the owner) and he installed a new ice maker in our Samsung refrigerator and installed a new lower heating element in our KitchenAid oven."

"I had an excellent experience with Scott! Very friendly and extremely knowledgeable. During the thermostat installation procedure he discovered two issues with my AC unit (one of the fuses was blown and also one of the wires was fried) and fixed both without any additional cost. Very happy with the service and will definitely be using them in future. Thanks Scott!"

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.

An HVAC system typically lasts between 10 and 30 years, with an average lifespan of 15 to 25 years. The longevity of the system is influenced by factors such as the quality of the unit, usage frequency, local climate, and how well it is maintained. Regular maintenance, including cleaning, filter replacements, and professional inspections, can help maximize its lifespan. Different components within the system have varying life expectancies. For example:

  • Furnaces: 15 to 30 years

  • Boilers: 20 to 35 years

  • Air Conditioners (AC units): 12 to 20 years

  • Heat Pumps: 10 to 20 years

  • Ductless Mini-Splits: 10 to 30 years

To figure out if your boiler is worth repairing or if you need to replace your boiler, first figure out how old the unit is. Boilers last 15 to 20 years, so if your unit is 15 years old or older, it may be better to replace the entire thing depending on the severity of the problems. If it’s not quite that old, then it’s probably worth repairing. Another thing to consider is whether your warranty covers any of the repair costs. If so, it may be worthwhile to repair your boiler to keep it running.

A furnace takes in cool air, heats it through the burner and heat exchanger, and sends the air on its way to warm your home. A boiler is a pressurized vessel that produces hot water or steam to heat the home and provide hot water. A boiler may or may not work together with a furnace.

Most propane boilers last 15 to 20 years with regular maintenance and proper care. The lifespan depends on the quality of the unit, proper installation, and the level of maintenance. Investing in annual service can maximize longevity and efficiency. Routine inspections and timely repairs prevent early breakdown, ensuring your boiler heats your home for years to come.
