We don’t recommend it. HVAC systems are more complex than you may believe. If you are not a professional, there are a lot of things that could go wrong during the installation. To handle the job, you’re almost always better off hiring an HVAC expert.

The average installation time for a complete HVAC system is three to five days.

whereas the typical lifespan of an HVAC system can range from 10 to 25 years, depending on your climate and type of heating and cooling system. However, if your HVAC system has been overworked by inadequate insulation and unwanted airflow (caused by unsealed air leaks), it may last less time.

Regular maintenance inspections are not required of you, but they are occasionally necessary. Even if there are no obvious flaws, we advise having an air conditioner checked at least once a year to make sure it is operating at peak efficiency.

Ventilation systems must be cleaned and maintained to help provide good indoor air quality in homes. A full service is advised every two years, with filter replacements needed every three to six months in between.

A professional inspection of your HVAC systems should be performed once a year. Therefore, if you have a furnace or a standard central air conditioner, you should maintain each of these systems annually. You should schedule this service once every six months if you use a heat pump system all year long.
