Your heating and cooling system is one of the most frequently used appliances in the house. If it’s been malfunctioning, brush up on the vocabulary an HVAC contractor might use to describe the problem or the solution. This will help you understand the unit better so you can stave off additional concerns in the future.

A Guide to Essential HVAC Terms

1. Preventive Maintenance

Your HVAC system needs regular care to maximize its life span. This also impacts how efficiently it runs. During your recommended bi-annual inspection, an HVAC contractor will perform preventive maintenance. This involves looking at essential components like the compressor, refrigerant line, and thermostat. If they find signs of wear or damage, they can resolve it before it becomes a larger issue. They’ll also prime your system by cleaning components and changing out the air filter so that it’s less likely to overwork itself, which can lead to breakdowns.

2. MERV Rating

Air filters are responsible for keeping your air clean to reduce respiratory problems. MERV, which stands for “minimum efficiency reporting value,” rates the filter’s efficiency. The higher the MERV rating, the better it can capture small particles. Most HVAC contractors recommend a rating of 10 to 13 for homes, but you may want a higher rating if a family member is allergic to pollen, dust, and other particles that can settle in the ductwork.

3. SEER rating

SEER stands for “seasonal energy efficiency ratio.” This measures the cooling power of your system divided by the energy it consumes to achieve desired temperatures. An inefficient system won’t cool your home as well and will also cause energy bills to skyrocket. Ideally, you should have a unit with a 13 or 14 SEER rating.
