Choosing the Right HVAC Unit for You


Finding a new air conditioning or heating system can be difficult. You have to consider price, size and type, among other features. There are a few factors you should consider when purchasing a unit. 

Product Efficiency & Price

The first feature to look for in an HVAC unit is an Energy Star rating. Products with an Energy Star rating meet the strict energy-efficiency guidelines of the U.S. Environmental Protection Agency. Although these units can be more expensive than non-starred ones, they use less power and will save you money over time.

SEER Rating

Another factor is the unit's SEER rating, or Seasonal Energy Efficiency Ratio. This metric measures how much air a system puts out for each unit of energy it consumes. Ratings in this area of the country range from 14 to 25, and the higher the rating, the more energy-efficient the unit. The right rating for you depends on your regional climate, how often you will use your unit and the size of your new system.


The most important factor for a successful HVAC purchase and installation is the contractor. Expert technicians will be able to determine what size and kind of unit you need, how a new unit will fit in your existing infrastructure, and the best products for your situation. To get a good contractor, you should ask for referrals, check an organization's background and reviews, and gather several price quotes.
