What is the average life expectancy of my HVAC system?

The average life expectancy of most units is around 10 to 20 years. As the unit ages, the efficiency of the unit can decrease significantly and require frequent repairs. Usually for older units the choice becomes either overhauling the system or replacing it. HVAC technology has produced more energy-efficient equipment which can dramatically improve conditions in the home.

Our fully-trained and certified technicians can provide a FREE in-home consultation of the cost of a new more efficient HVAC unit as well as an estimate of your utility bills savings. Over time this savings can offset the cost of a new unit making it a financially sound decision and better for the environment as well.

How often do I need to my HVAC unit serviced?

We recommend having a regular tune-up twice a year. It’s best to schedule your tune-up at the beginning of each heating and cooling season as you want to make sure your unit is working efficiently before the weather becomes too hot or cold. You can however schedule your tune-up at any time.

What is SEER?

SEER stands for Seasonal Energy Efficiency Ratio. The higher the SEER rating the greater energy efficiency. The SEER measurement ratio is calculated by measuring the heat pump cooling efficiency, or the cooling output for an average cooling season divided by the total electric energy input during the same time frame.

How can I improve the quality of air in my home and make circulation more efficient?

Maintaining a comfortable temperature is only one part of sustaining high quality air in your house. Your air conditioning unit also inhibits mold growth and increases comfort in your home by wringing excess moisture out of the air. Pollen and pet dander is filtered and removed as well. This helps people with conditions such as asthma and allergies feel more at ease.

There may be times throughout the year where you do not need to turn on heating or air conditioning. If you have a quality ventilation system in your home, even moving air through your AC system’s fan can feel cooler than still air. This eliminates the temperature regulation which can lower your energy bill and let you enjoy a pleasant spring or fall day. ERVs, or energy-recovery ventilators dehumidify air and use heat from the exhaust to pre-condition air.

How often should I replace my air filter?

A general rule of thumb is to change your air filter every month. This creates a habit and is a safe duration of time. This is even more important during times of peak use. Some homeowners will clean their filters before changing it the following month, but this should only be done during seasons when your heating and cooling is used less frequently.

Should I repair or replace my unit?

The only real way to answer this is to have a technician take an in-depth look at your system. Multiple factors will influence the decision to repair or replace. Our certified, courteous and on-time HVAC professionals will be happy to diagnose your heating or cooling system and arm you with the knowledge and recommendations to make the right choice.
