Purchasing a New HVAC System

Previously we have discussed the importance of hiring the right contractor when it comes time to have a new HVAC unit installed. Today we are going to discuss the importance of buying the right HVAC unit. HVAC systems come in all different styles and size. Getting the correct one for your home is important not just in keeping you comfortable, but in keeping your wallet nice and full as well.

Determining the Correct Capacity

Some contractors may look at your current HVAC units and tell you to simple buy a new one with the same capacity. This may not be best for you. HVAC units have probably changed a lot in the time since you last had one installed. You should have a load assessment performed. This will determine exactly what the heating and cooling needs are for a home of your size. This assessment should include a heat-loss calculation which factors in walls, attics, floors, windows and doors. These are all common locations for temperature controlled air to escape.

Energy Efficiency

This is going to be one of the most important things to consider when you are shopping for a new HVAC unit. The Seasonal Energy Efficiency Ratio (SEER) of your unit tells you have energy efficient is it. The higher the SEER rating, the more efficient it is. Currently the U.S. Department of Energy dictates that any new split system central air conditioning unit installed in New Mexico must have a minimum SEER rating of 13. This does not mean you are limited to a 13 SEER HVAC unit. The higher the SEER rating, the more expensive the unit is going to be. However, higher SEER units are going to save you more money in the long run. Choosing the right unit for you involved balancing upfront cost with savings down the road.
