If you have a new addition to your home, you may be looking at different options for heating and cooling systems. In some cases you may be able to add to an existing HVAC system, but in other cases it's better to plan an entirely new heating and cooling system for your addition. Here are some ways to tell which method is best for you.
If Your Old System Has Outdated Technology
Some types of heating and cooling technology make it difficult for technicians to work with your existing system. For instance, steam heating systems have lost popularity and you might have difficulty finding a heating repair contractor who is willing to extend this system. Instead, you might choose to build a newer unit with improved technology for your home addition.
If You Wish to Incorporate New Heating and Cooling Methods
Another reason to choose a new heating system is if you want to try out some new heating methods in your home. For instance, geothermal heating units are becoming popular in homes, and they can potentially save you a lot of money because they make use of existing environmental conditions to heat and cool your home. Heat pumps and radiant floor heating are other methods that can be very energy efficient. Trying out a new heating method in your addition can be a great way to get your feet wet with a new system without entirely redoing your home's existing HVAC work.
When Your Existing Heater Isn't Strong Enough
Another time when it's best to install a new furnace and air conditioner is when your existing units won't be strong enough to heat and cool the entire home. Each air conditioning unit, for example, is rated for the amount of BTUs (British Thermal Units) of cold air that it can produce per hour. Overloading the system's running capacity is not a good idea as it can lead to a premature breakdown of your equipment. Instead, it may be a better investment to install a smaller, complementary air conditioning unit and HVAC system in your home addition.
In short, there are a lot of things to consider before installing additional ductwork in an existing HVAC system to heat and cool your addition. Have an HVAC contractor run the numbers to determine whether it would be more costly to add new ductwork or create an entirely new system for your addition.
