How do I know what is the correct capacity of a new furnace for my home?

Posted On: February 17, 2024

How do I know what is the correct capacity of a new furnace for my home?

Determining the correct capacity of a new furnace for your home involves several factors.


Here's a step-by-step guide to help you determine the appropriate capacity:


Calculate the Size of Your Home: The size of your home is a primary factor in determining furnace capacity.


Measure the square footage of your home, including all finished living spaces.


Consider Climate: The climate of your region plays a significant role in determining the capacity of the furnace you need.


Colder climates require more heating capacity compared to milder climates.


Insulation and Energy Efficiency: Evaluate the insulation and energy efficiency of your home.


Well-insulated homes require less heating capacity as they retain heat better.


Existing Heating System: If you're replacing an existing furnace, consider its capacity and whether it adequately heated your home.


If you were satisfied with its performance, you might opt for a similar capacity.


Manual J Calculation: The most accurate method is to perform a Manual J calculation.


This calculation considers factors such as the home's size, insulation, climate, number of windows, and more to determine the precise heating load your home requires.


HVAC professionals typically perform this calculation.


Consult HVAC Professionals: It's advisable to consult with HVAC professionals or contractors who can assess your home's specific needs and recommend the appropriate furnace capacity.


They can conduct a Manual J calculation or use their expertise to provide a suitable recommendation.


Avoid Oversizing: Avoid the temptation to oversize your furnace, as this can lead to inefficiencies, increased energy costs, and discomfort.


A furnace that's too large may cycle on and off frequently, leading to unnecessary wear and tear and inconsistent heating.


Consider Energy Efficiency Ratings: Look for furnaces with high energy efficiency ratings (e.


g.


, AFUE - Annual Fuel Utilization Efficiency).


High-efficiency furnaces may have lower capacities but can still effectively heat your home while reducing energy consumption and utility costs.


By considering these factors and seeking professional guidance if needed, you can determine the correct capacity of a new furnace for your home, ensuring optimal comfort and efficiency.

Very pleased with the installation of our new furnace and A/C unit. From quotation stage to the completion of the job Twintech was very professional.
Thank you for a job well done.

by Darren, Pickering on Twintech Heating and Cooling

My old water heater quit on me. I called TwinTech. In less than 4 days, I had my new water heater installed and the old one taken away. The whole process was quick, easy, pleasant, and well done. This is the third time I've dealt with TwinTech and I've been satisfied each time.

by Private User on Twintech Heating and Cooling

I had them replace my furnace last year. When it came time for the air conditioner this year, I did not hesitate to call Twintech again. I will also have them perform regular maintenance on them.

by Robert, Ajax on Twintech Heating and Cooling

We required a new HVAC replacement after running the old
system for 18 years.
Dave understood our requirements and gave us a quote that
covered all the necessary items.
Installation was fast and very tidy. Everything works as
it should. Our thanks to Greg, Mitch and others for their
excellent work. Recommend this family owned business to
anyone else, considering HVAC or other work.

by John Armstrong, Pickering on Twintech Heating and Cooling

I needed a new furnace and A/C to replace my 21 yr. old units, and went to the internet to view potential companies in May, I received 3 quotes,
and chose Twintech based on their salesman Dave who was very detailed and covered off everything on what Twintech was all about,
an extremely dedicated company with so many years of experience, and after reading the on line reviews I was sold on Twintech, who did not disappoint as the installation team were top notch with Greg leading,
I would highly recommend this company without any doubts, in my books they are first class all the way. Our new Amana furnace and A/C are working perfectly !

TwinTech is an excellent and honest company! I called them for a second opinion after being told by another company that I needed to replace my furnace. Turns out this was not the case at all!

I definitely recommend TwinTech!
