Purchasing your first HVAC system is an exciting but potentially daunting task. With so many variables to consider, you might not know where to start. When consulting an HVAC contractor, use the following questions to narrow down your options.

How Do I Measure Energy Efficiency?

There are a few different ratings for energy efficiency. The Energy Efficiency Ratio (EER) measures the cooling power of the AC system per unit of power consumed. It’s usually only measured on the hottest day of the year. The Seasonal Energy Efficiency Ratio (SEER) gives you the average efficiency over an entire season.

Perhaps the most well-known is Energy Star®, which rates an HVAC system according to how it contributes to nationwide energy savings and its overall value. Combining these ratings with your HVAC contractor’s knowledge will help you choose the most energy-efficient option for your home.

What Size HVAC System Do I Need?

The answer mostly depends on the size of your home. If you get a unit that’s too big, you’ll use up excessive energy and pay a higher bill. If your unit is too small, it won’t heat or cool your home thoroughly.

While your HVAC contractor will answer this question best, as a general guide, look at British thermal units (BTU). These measure the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit. Heating systems use BTUs to measure their energy output. A 500-square foot home will need a system that uses 14,000 BTUs to heat, and a 2,500-square foot home will need 34,000 BTUs.

How Can I Improve Indoor Air Quality?

All HVAC systems come with filters to help improve indoor air quality. However, if you have pets or people in your home with asthma or other lung conditions, you may need extra filtration systems. High-efficiency particulate arrestance (HEPA) filters can remove 99.97% of airborne particles.
