Most modern homes are constructed with central heating and air conditioning units. These HVAC systems have one unit that filters and regulates air temperature. It utilizes a ductwork system to disperse air throughout a home. Learn the answers to common questions about these systems below.

A Guide to Central HVAC Systems

How long do central heating and air conditioning units last?

The average life span for a central HVAC system is 15 to 20 years. If you perform routine maintenance, it can last over two decades, while units that aren't maintained properly may only last around 10 years. Calling an HVAC contractor for annual inspections helps keep the appliance operating efficiently for years to come. Proper installation also plays a large role in how long the unit lasts.

How can you improve the air quality of your HVAC system?

Regular duct cleaning from an HVAC contractor is the best method for keeping air flowing cleanly in your home. You can also install humidifiers, dehumidifiers, and air purifiers to boost air quality in the rooms that need them. If air quality is still poor, there may be an issue in your system that needs to be addressed by a professional.

How often should you change the air filter?

Effective air filters are necessary, as they keep dust, dirt, and allergens from diminishing your indoor air quality. Depending on the type of air filter the system uses and how many people and pets live in your home, you'll need to replace it every three months or even monthly. HEPA-grade filters last longer than standard designs and filter air more effectively.

Why is your air conditioning unit not cooling?

If your system isn't performing as well as it typically does, it could be the result of a number of issues. You may need to replace the air filter, adjust refrigerant levels, or have the ducts repaired and cleaned. There might also be issues with the electric control feature, internal sensors, and drainage. All of these systems are fixable with the help of an HVAC contractor.
