Bigger Isn't Better: All About Manual J

Manual J is an industry standard that describes a method for determining, basically, how “big” your air conditioning system should be for the size and type of house you live in.

SEER Ratings: Make the Right Decision

Homeowners and contractors, alike, are generally confounded by the SEER acronym. SEER stands for Seasonal Energy Efficiency Ratio. The higher the SEER, the more energy efficient the air-conditioner. Ok, but how high is high enough? Let's take a look.

When should you schedule a preseason?

The concept of a “preseason” can be misleading. The outdoor temperatures prior to the season may be outside the parameters needed to accurately check the refrigerant charge in your air-conditioner. Here are a few tips to keep in mind when scheduling your next preseason tune-up.
