Among the many factors to consider when installing a new HVAC unit, the size is one of the most important. A system that is not correctly sized to suit the area it affects can cause problems, including wasted money and energy. Compatible systems should work effortlessly and provide ample control to the owner. Many issues attributed to malfunctioning HVAC systems are caused by an inaccurate size, which makes it imperative to be aware of key areas of concern when shopping for a new or replacement unit.
Efficiency and Cost
American air conditioners are scored with the Seasonal Energy Efficiency Ration (SEER). Higher SEER values indicate more energy-efficient units. The minimum SEER value required by law is 13, and exceptionally efficient systems have a score of 20 or more. The initial purchase price of energy-efficient HVAC systems can be higher than those with lower SEER values but can save you money in the long run when it comes to your monthly energy bills.

HVAC units provide air conditioning as well as heat. It’s important to outline how your system will be used by taking into consideration factors like climate, hours of operation, and space demands. Knowing your needs ahead of time will make it easier to compare models when shopping for systems and allow you to choose a system that best suits your specific needs. Other practical considerations to keep in mind include the number of different fan speeds, the power consumption of the unit, and if a sleep mode is offered.
Understanding how much noise a system will produce is an important concern for both internal and external requirements. You may desire a quiet internal system for an office or retail setting, while an external unit may need to meet municipal or building regulations. Before purchasing a unit, be sure you are aware of the regulations in your location. A rooftop unit is a popular choice because its location promises reduced noise levels, frees up more ground space for parking, and maintains the aesthetic of your building.
Some HVAC units are considered smart systems and allow you to monitor and manage your system from anywhere in the world through an app on your smartphone. Smart HVAC units also monitor energy output and many include additional features like zoning and scheduling which help you to control your energy costs.
While everyone wants to find a budget-friendly HVAC system, it may be worth a little extra money upfront to purchase a system with a history of reliable operation and long-lasting efficiency. Factoring in your expected lifetime of use can provide an annual cost that may make a more expensive option more affordable.
Compatibility is key when selecting the right size HVAC system for your property. Make sure you have outlined your requirements before shopping for a unit and don’t hesitate to contact a certified HVAC specialist to discuss new systems and features that might be a perfect fit for your needs.
