What does HVAC mean?

This acronym stands for Heating, Ventilation and Air Conditioning.

How long do A/C and heating units typically last?

HVAC systems can last a long time if regularly maintained. They can last 12-20 years.

What does SEER mean and why does it matter?

SEER, the Seasonal Energy Efficiency Ratio, measure an air conditioning unit’s efficiency. Higher numbers mean units use less power. Selecting the correct amount of air conditioning and installing the system properly can affect the true SEER of an HVAC system. SEER is roughly equivalent to how we use a car’s reported fuel economy. In certain conditions 30 MPH is possible, but not during rush hour sitting creeping along IH-10, for example.

What is included in air conditioning and heating maintenance?

We recommend servicing systems in the milder fall and spring seasons before the heat of summer or the cold of winter. Find out what heater performance maintenance and air conditioner maintenance involve.

Why do I need to change my air filter regularly?

Regular filter replacement helps your heating and cooling system operate at peak levels and improves indoor air quality. It is important to change filters regularly to ensure proper air flow and to keep your home free from dust, allergens and germs. Your service technician can recommend filtering and purification options and a replacement schedule for your unit.

How often should I replace my filters?

In general, American Air Heating & Cooling recommends that you replace your disposable filters at least once each season. If you have washable filters, they should be cleaned once a month. Your American Air Heating & Cooling technician will recommend a replacement schedule that delivers the optimum efficiency and filtration for your specific system. American Air Heating & Cooling can help you maintain your system by signing you up to one of our Preventative Protection Plans. This includes cleaning and inspecting your HVAC system once or twice each year (dependent on your plan choice). We recommend that you visually check filters and filtering equipment monthly. If filters look dirty, they need to be cleaned or replaced.

What does MERV mean?

MERV is an acronym that stands for minimum efficiency reporting value. MERV is measurement scale (1-16) created by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) to rate the effectiveness of air filters. The higher the MERV, the more efficient the air filter is and the harder it is for your system to draw air through the system. We generally recommend between 7-11 MERV filters for most circumstances.

Where can I find information about energy efficiency tax rebates from city, state, and federal sources?
