HVAC FAQs – Commercial & Residential

What is HVAC?

The Acronym ‘HVAC’ stands for Heating Ventilation and Air Conditioning.

How often should my heating & A/C system be checked?

Annual check-ups by a qualified technician are recommended for proper efficiency. Get your heating unit tuned up in the fall, and cooling system tuned up in the spring. Humidifiers, air to air exchangers, etc. are also serviced during a “tune up”. Regular service inspections can prolong the life of your HVAC equipment and detect potential issues before they cause breakdowns and become more costly.

What can I do for my family members with asthma or allergies?

A good first step is to get a whole-house air-filtration system. The Lennox healthy climate system has been rated the best in the industry by leading consumer advocates. Another great idea is to install a SteriLight™ system by Steril-Aire®. It destroys mold and microorganisms that might cause allergies in your home or building.

What is electronic zoning? What are the benefits?

An electronic zoning system divides your building into sections. Each section is given a thermostat. A building with proper zoning has a constant temperature in each room, saving money and energy.

Why are some areas in my building hotter than others?

There are two possible options: Your thermostat location and/or a problem with your ductwork. You’ll most likely need an HVAC certified company such as ABEL Heating and Cooling to help you remedy the situation.

How humid should my building be?

During a Minnesota winter, 35% relative humidity is recommended.

Is a Higher SEER Rating Better for Your HVAC System?

Most industry experts compare a SEER rating to a car’s fuel efficiency. The higher the SEER, the more efficient the cooling system should be.
