Learning About Commercial HVAC Systems

Hello, my name is Jacob. I would like to talk about proper installation and repair of the HVAC system in your commercial building. Full scale HVAC systems for commercial buildings require ongoing maintenance and repairs to keep every floor and room at a comfortable temperature. These temperature control systems also control the air quality in the building by sending the airflow through filter elements. My site will cover all aspects of the upkeep needed for these systems. I will also talk about the benefits of keeping your air quality and temperatures at desirable levels. Thanks for coming to visit my website.

Do You Need To Replace Your AC Unit With A Heat Pump?

Isaiah Chapman

When it comes time to replace your AC unit, your first thought is probably not to replace your air conditioning unit with a heat pump, but in some cases, it may be a good idea. While a heat pump can cool your house just like an AC unit, it adds functionality in that it can also heat your house. Even if you already have an existing furnace, a heat pump can still be a good value. 

For Light-Duty Cooling

If you live in a moderate climate, you probably don't need much in the way of cooling. When you place a heat pump in heating mode, it will use the coils on the outside of your house to extract heat from the outside air. While a heat pump can extract heat even when temperatures fall to around freezing, it will be most efficient when temperatures remain moderate. Thus, you should only use a heat pump as your primary heating unit if you don't have to worry about sub-zero temperatures. 

Why not Just Go with a Furnace?

You may be wondering at this point if a heat pump does not heat efficiently when temperatures fall to around freezing, why use one at all? It comes down to efficiency and operation costs. Because a furnace must create its own heat, it will never be able to create more than one unit of heat for every unit of fuel it uses. In fact, the best furnaces top out at about 97% efficiency. On the other hand, a heat pump only has to move heat from one place to another. Some heat pumps can move 2.75 units of heat for every unit of electricity they use—this is equivalent to 275% efficiency. Furthermore, if electricity costs less than natural gas in your area, using an air-source heat pump in your home can really help you save money. 

What if You Already Have a Furnace?

If you live in an area where temperatures drop below freezing in the winter, it can still make good sense to use a heat pump. At the very least, you can use your heat pump to heat your home during the spring and fall when the temperatures are more moderate. You can also use your heat pump to cool your home during the summer, but you will still have your furnace to provide heating when winter temperatures are at their coldest. 

Replacing an old air conditioner gives you the opportunity to optimize your HVAC system. At the very least, you should look for the most efficient AC unit you can afford, but you should consider installing a heat pump so that you can use it to help save money on heating costs during the spring and fall.
