Checklist for Buying a New HVAC Unit

Checklist for Buying a New HVAC Unit

Check off all these boxes before settling on a brand new HVAC unit.

Your home’s heating and cooling system keeps you and your family cool in the summer and cozy in the winter. It is what makes your home breathable and comfortable. If your unit begins to cost you higher-than-usual energy bills, unusual noises, higher humidity, and less efficiency overall, it’s time to get a new appliance. To get the best HVAC unit for your home, here is a general checklist to advise your steps.


With many models and brands on the market, it may be difficult to know what the differences may be. Generally, there are several parent brands that are bigger household names and may sell for more, but their child brands perform just as well. Every brand has decent quality at least, but it does not hurt to research more to see what might be to your liking.

SEER Rating

HVAC systems have a SEER number–that is, a Seasonal Energy Efficiency Ratio rating. The higher the number, the more efficient the appliance is. However, just because it has a higher rating doesn’t mean it is right for your home. The efficiency should match with your climate; in Maryland, the bare minimum efficiency number is 14 SEER.


Along with the SEER rating, an HVAC unit also needs to be the appropriate size for the house. Otherwise, the machine will be too powerful or not powerful enough to cool and heat the home. A professional HVAC contractor can measure this for you and recommend the right kind of product.


A warranty, depending on the type, covers the cost of unforeseen repairs due to a mishap by the manufacturer or the installer. Instead of having to pay extra for an otherwise fantastic machine, your warranty can save the day. Be sure to investigate the details of your warranty, such as whether it is prorated or not and what it covers, before sealing the deal.

Service & Maintenance

Every HVAC unit needs maintenance, even if it is as simple as changing the air filter every 2-3 months. There may also come a time when it needs repair. HVAC service pertains to repairs, while HVAC maintenance consists of routine checkups. Understand what the best treatment for your unit would be to keep it running smoothly for as long as possible.
