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.

My old furnace had finally broken down for the last time when contacted twintech to have a new furnace installed…They were prompt, knowledgeable and very reasonably priced. They did such a great job i tell all my friends and family about this company.

by Damien McIsaac. Ajax on Twintech Heating and Cooling

To whom it may concern, I recently had TwinTech (Greg and Grant Dainty) replace my furnace and service both my gas fireplaces and air conditioning unit. They were professional, courteous and very fair in their pricing. I would gladly recommend TwinTech to anyone needing work done. I can be contacted at 905-626-XXXX.

by Blair N. - Toronto on Twintech Heating and Cooling

My Fiancé and I have relied on Twintech Heating and Cooling now for the better part of the last 10 years. In that time, Greg has installed a furnace, an air conditioner, and a heat-pump at our residence in Toronto. In each instance Greg and his team were a pleasure to deal with. They were courteous and professional throughout the whole process and the quality of their work is first rate. Our experiences have always been extremely positive and we have referred his services numerous times to our friends and family. Without hesitation, I would recommend Greg and TwinTech Heating and Cooling to anyone looking to service or replace their existing heat/AC equipment

by Ruth on Twintech Heating and Cooling

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 did not need a new furnace. TwinTech did not push to make an unnecessary sale and saved me from a huge expense. Bob and Mitch were extremely professional and above all honest! I definitely recommend TwinTech!
