Types of Furnaces

There are three main types of furnaces available. Each furnace type has its own benefits, ways of functioning, and may be more suitable for a particular area or type of home than others.

Single Stage
This type of furnace has only one stage of operation. It can either be turned on or turned off.

Two Stage
This type of furnace has two settings, full and half speed. This is a more efficient way to heat and provides for better comfort because it can move the air at a slower pace.

Variable Stage or Modulating
This kind of furnace modulates the speed and heat output based on the temperature outside and the desired comfort level. This furnace only works as much as you need it, this makes it the most energy efficient type of furnaces.

Signs It’s Time to Replace Your Furnace

A typical furnace can last up to 15 to 20 years. This is heavily dependent on how well you have maintained it during its life and if you have had professional maintenance performed on a regular basis. Below are a few signs that it may be time for a new furnace:

  • Steadily climbing gas and electric bills
  • Increased frequency of furnace repairs
  • Grinding, popping, rattling, or banging noises
  • Excess dryness or dust in your home

If you think it’s time for a new furnace, or you have questions about furnaces or our services, please call us at 978-562-5309 or request service online.

“This was just my annual check on the heating system. I appreciated the e-mail telling the technician was on his way. When he arrived he was friendly and requested I bump up the thermostat so he could run the tests. He was quick despite having to climb up and down the pull-down stairs to the attic.”

– Patricia (Pat) M.

“Fast estimate. Excellent price. Installed new gas combo boiler/water heater in 2 days. The installation team was efficient, friendly, and professional. Couldn’t be happier with the installation!. I will be using Chaves for HVAC from now on.”

“Mike had had a busy day, arriving a bit late. Explained when I had to leave to go elsewhere, he noted that the furnace checkup could be done in that time frame. Which indeed it was. He was polite, concerned, and efficient. He explained clearly what he had done and was willing to answer questions. He seemed to be the ideal serviceman! And I got to my appointment on time!”
