Is Size Important in HVAC?

The working of your HVAC system greatly depends on the efficiency, the maintenance, and the model. However, size is also an important factor to be considered while considering an HVAC system for the home. The process can seem tricky, as the systems come in various sizes and shapes. The size of your HVAC system impacts important areas, such as cost of installation, monthly energy bills, efficiency, and overall comfort. 

Premier Heating & Cooling tells you the various factors influenced by the size of the HVAC system. 

Cost of Installation

Installing an HVAC system might not be a big factor, but if you want to replace an old system or install a new one (for a new house or room), you must remember that HVAC units are not designed to last forever. Scheduling your unit for preventive maintenance and timely repairs allows your system to last anywhere from 10-15 years. 

The size of the unit affects the pricing too. Usually, the larger the unit, the more expensive it is. Of course, it would cost you more, but a smaller unit cannot provide you with the same level of cooling or heating (depending on the design and size of your house or room). Furthermore, if your space is larger, i.e., you have a spacious home, installing a small unit can lead to problems such as reduced efficiency later. 


Efficiency is yet another determining factor to be considered when purchasing a new model or looking for a replacement. The efficiency of an HVAC system states how well it can heat and cool the air and move through the vents into your indoor space. Every unit comes with a SEER efficiency rating. The higher the SEER ratings, the more efficient the unit. However, the units with more SEER ratings will cost you more, but it will be a better investment in the long run. Keep in mind that a system with very high-efficiency ratings will not operate perfectly if it is not properly sized for your home.

Monthly Bills

If your unit is larger than the space in your home, it will cycle more frequently, leading to increased heating and cooling bills. And if the unit is too small, it will have to run for more extended periods to reach your desired temperature. This results in increased bills. Therefore, while choosing your heating or cooling unit, you should consider the home’s square foot and other needs. 

Overall Comfort

Comfort is arguably the first and foremost need and should be considered when installing a new heating and cooling system. A unit that is not sized well will fail to provide the required indoor temperature. In addition to being stuck, you could also notice issues with moisture levels. Too much moisture could make your space feel soggy and unpleasant. It could damage your wood flooring, wall, furniture, electronic equipment, and other devices or items in your home.
