Most homes in the Lower Mainland contain heating and cooling systems to ensure comfortable temperatures throughout the year. However, many homeowners don’t realize the importance of compatibility when it comes to using a heating system and AC together. If they don’t work in tandem, your home’s temperature, air, and energy consumption will be severely affected.
Below, we’ll discuss how your heating and air conditioning work together, signs of compatibility issues, and why it may be time to upgrade your current HVAC system with a top-quality one from DirectBuy Furnace. Keep reading to learn more!
How Furnaces and Air Conditioners Work Together
Furnaces and air conditioners work together to regulate the temperature and airflow within your home.
While your furnace provides heat indoors, the air conditioner circulates cool air from outside. Both systems require the use of your vents and ductwork to transport air and temperature successfully.
Your furnace and AC use the same air blower, are operated by the thermostat, maintain the temperature and humidity, and work to clean, condition, and re-circulate the air within your home.
The AC evaporator also uses the same system as the furnace to transfer excess humidity and heat outside. If there’s a malfunction within the system, this can cause the AC to freeze.
Overall, if your heating and air conditioning aren’t compatible, you may encounter several issues that can cause discomfort in your home and increase the wear on your current HVAC system.
Signs of Compatibility Issues
What are some indicators that your furnace and air conditioner may be mismatched? We’ll examine a few common signs below:
Old Furnace
If you live in an older home, in all likelihood, your current furnace has not been replaced in several years. Most furnaces last 15-20 years, and if yours is nearing its expiration date, its components may not work well with a modern AC unit.
Uneven Heating and Cooling
If you notice drastic temperature differences from one room to the next, this may indicate that the components in your heating and cooling systems are not working well together, preventing air from both to reach certain areas of the house.
High Energy Bills
When your heating and air conditioning systems aren’t well-suited, they have to work overtime to produce any airflow. If your furnace is old, it has to work even harder as its components continue to wear down.
Your heating and cooling systems need to consume a lot more energy to produce airflow in these conditions. So, if you’ve noticed an uptick in your utility bills despite using your AC and furnace normally, this could indicate that these units are mismatched.
Frequent Errors and Repairs
If improperly matched, AC and heating units can strain each other, resulting in constant issues and equipment breakdowns. If you’re regularly calling for repairs, it may be time to consider replacing your current HVAC system rather than spending money on seemingly temporary fixes.
