Facts to Know Before Purchasing a New HVAC System – Part 2

As discussed in Part 1, the most important resource for selecting a new HVAC system will be a licensed electrician who is very experienced in installing them. An HVAC installation requires both solid engineering and working with a home’s existing wiring, ventilation, ductwork, etc. Consider a good electrical contractor a sound investment because the project will run from $2,500 to about $15,000 on average. Part 2 will cover Air Quality, Energy Efficiency, Maintenance, and Noise Levels. 

Air Quality

If IAQ (indoor air quality) is a health concern for your family, consult with your electrician before beginning the project. Solutions that will improve air quality include denser air filters, humidification controls, air purification appliances, and ventilation systems.

Energy Efficiency

According to the U.S. Department of Energy, 50% of home energy usage is applied to cooling and heating. It makes sense that how much energy an HVAC system requires should play a big factor in your decision.

The heating efficiency of a furnace is measured by its AFUE (Annual Fuel Utilization Efficiency). Furnaces that are very efficient have a higher AFUE number.

The energy efficiency of air conditioners is measured by SEER (Seasonal Energy Efficiency Ratio). A/C units that are very energy efficient have a higher SEER rating.

The energy efficiency of heat pumps is measured by the HSPF (Heating Seasonal Performance Factor). This number measures the heating portion of the heat pump. Heat pumps that are very efficient have a higher HSPF number.

For a new HVAC system to attain its greatest efficiency as indicated by its EnergyGuide Label, a licensed electrical contractor will be required for proper installation.


An HVAC system needs regular maintenance by a qualified technician to keep its warranty valid. Subscribing to a maintenance program can save money in the long run. Do your part by replacing your HVAC air filters every one to two months.

Noise Levels

Consult with your electrician regarding HVAC noise levels to ensure you’re purchasing a quiet system. Select a system that has a noise level measured below 60 db.
