"Jim with North Alabama Technical Services removed some items from my computer so that I could send emails and attend to items I needed to address that day. As planned, the next day he thoroughly cleaned my computer, he also made helpful suggestions while working on my computer. I would call him again if needed and I thought the fee was reasonable."

Install Boiler questions, answered by experts

Depending on the size of your home and system, as well as any upgrades or add-ons you choose, it may take between three and five days to completely replace an existing HVAC system from start to finish. Your contractor should be able to give you an estimate before they begin the actual replacement.

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.

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

The best time of year to purchase or replace an HVAC system, including components like an air conditioner or furnace, is during the off-season—spring and fall. During these periods, HVAC professionals are less busy than in summer and winter, when extreme temperatures create urgent demand. Shopping during the off-season can lead to savings of 10% to 15% on an AC unit and allows you more time to find the best deal and other cost-saving incentives. Typically, air conditioning units go on sale in the fall after demand drops, while furnace prices tend to decrease in the spring.

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.
