Question 1

How much does it cost to replace my home heating system?

Accepted Answer

Expect to spend between $3,500 and $10,000* on the type of HVAC system you'll need to be efficient. Before making a purchase, keep in mind that a furnace with a higher AFUE rating will operate more efficiently than its competitors and consequently cost more upfront. The word "upfront" is crucial because, in the long run, a higher-efficiency furnace allows you to save more money on utility costs.

Question 2

What is the average lifespan of a furnace?

Accepted Answer

A properly cared-for furnace can last for at least 15 to 20 years, and by performing annual maintenance and being prompt with repairs, you can increase the lifespan even further.

It's a good idea to start looking at new equipment when your furnace is about 15 years old so that you are ready to replace it when the time comes. You should research the most recent, cost-effective options and learn about their features. If energy conservation is a top priority, you should become familiar with the Annual Fuel Utilization Efficiency (AFUE) rating.

Question 3

How do you know if your furnace is dying?

Accepted Answer

There are a number of indicators that your furnace needs to be replaced or undergo major repairs. Some of the most typical are listed below:

1. If your furnace begins to make a louder noise than a faint humming, there is probably a problem. These rumbling, clicking, and crunching sounds are just a few examples. Check it out if it sounds strange.
A furnace is likely on its way out if you notice that you are spending significantly more than ever on your heating bill. Repairs might only delay this; a technician can advise on whether or not they are necessary and if replacement is a better option for you.
Your home's uneven heating may indicate that you need to replace your furnace. The furnace is likely losing its heating capacity if some rooms are not as warm as they usually are while others are unusually toasty. This will only get worse until the furnace exhausts itself.

Question 4

What size furnace do I need for my home?

Accepted Answer

Determining the appropriate furnace size involves thinking about square footage, climate, insulation, and home layout. A Manual J calculation, performed by HVAC professionals, assesses heating requirements accurately. Factors like ceiling height, windows, and local climate impact sizing. Oversized furnaces cycle frequently, wasting energy, while undersized ones struggle to heat adequately. Professionals analyze these aspects to recommend the right furnace size, typically ranging from 40,000 to 120,000 BTUs for average homes. Consulting the experts ensures efficient heating tailored to your home's specific needs.

Question 5

How do I know my new furnace is energy efficient?

Accepted Answer

To ascertain furnace energy efficiency, check its Annual Fuel Utilization Efficiency (AFUE) rating. Higher AFUE percentages denote greater efficiency. Modern furnaces usually have AFUE ratings ranging from 80% to over 98%. Additionally, look for ENERGY STAR certification, indicating compliance with stringent efficiency standards. Variable-speed motors and dual-stage burners also enhance efficiency by adjusting output to match heating needs. Evaluating these features ensures optimal energy performance, lower utility bills, and reduced environmental impact, making your investment in a new furnace worthwhile.
