Heating and Air Conditioning questions, answered by experts

You should have your HVAC serviced at least once per year. A HVAC pro can perform maintenance twice a year if your unit is older or has many issues. You can expect to pay between $100 and $550 for HVAC maintenance, which includes a thorough tune-up, routine service, proactive and reactive maintenance, and emergency maintenance services.

Most AC units last between 10 and 20 years, but lifespans depend on the type of air conditioner. For example, central AC units last for 12 to 17 years with proper maintenance and regular inspections from a professional. Window AC units, on the other hand, last between eight and 10 years.

There are several common types of HVAC systems that you may have, including split systems, hybrid HVAC, duct-free systems, packaged heating and air, geothermal heating, or even portable units for heating or cooling. If you aren’t sure which type is in your home or are looking to install something different, you should consult an HVAC pro to determine which option is right for your heating and cooling needs.
