How to Determine the Right Size HVAC Unit for Your Home
Determining the right size unit for your home can be challenging. If your system is too small, it may not be able to keep your home comfortable. On the other hand, an oversized system will cost more to operate and may wear out faster. To ensure your unit is the right size, our technicians can help you calculate the correct BTU rating for your home.
Calculating the correct BTU rating for your home:
- Multiply the length of your home by its width to get the square footage of your home.
- Add 10% to the square footage of your home to account for the area of your home that is not heated.
- Divide the square footage of your home by 43,560 to get the approximate number of BTUs your furnace or boiler should have.
After determining the correct BTU rating for your home, our technicians can help you find a system that fits your needs. We can explain the options available and help you compare different models to find the most efficient system for your home. We can also help you calculate the estimated yearly cost of each unit to ensure you get the most cost-effective system for your needs.
Signs It's Time to Replace Your HVAC System
As your heating equipment ages, it may become less efficient and costlier to operate. If your system is old and showing signs of wear, you may want to consider replacing it. You may also want to replace your system if it is failing to keep your home comfortable or if repairs are becoming too expensive.
Some signs you may need to replace your system:
- Your system is more than 10 years old
- Your energy bills are increasing
- Your system fails to keep your home comfortable
- Your system requires frequent repairs
- Your system makes loud noises when it operates
If you are considering replacing your unit, our technicians can help you choose a new system that is the right size for your home and provides the level of comfort you desire. We can explain the options available and help you compare different models to find the most efficient system for your home. We can also help you calculate the estimated yearly cost of each unit to ensure you get the most cost-effective system for your needs.
