Heating and Air Conditioning FAQs, answered by experts

The standard HVAC warranty is around five years. Still, many brands offer an extension to 10 years if you register the product within a specific timeframe, typically 60 to 90 days post-purchase or HVAC installation. Over the past decade, warranty periods have substantially increased, shifting from 3-5 years in the 90s to the now-prevalent 10+ year warranties. Both warranty types cover parts failing due to manufacturer defects, incurring no additional costs. Some manufacturers provide extended warranties surpassing the usual 15- to 20-year window, though these often involve extra fees. 

It all depends on the unit’s SEER (seasonal energy efficiency ratio). A higher SEER rating means better efficiency and lower costs for your energy bills. 

Take a look at the product you’re considering purchasing and compare it to other models to decide which one is affordable upfront but will keep your energy costs low over time.

Yes, it’s important to turn off your AC sometimes to give it a break and prevent it from freezing up. If your AC runs all the time, your system’s parts will wear down quicker, which may mean that you need to replace it sooner. Plus, using your AC constantly uses more electricity and leads to higher energy bills.

Keeping your air filter clean is crucial for your heat pump's efficiency. As a general rule, you should check your air filter every 1 to 3 months. However, the actual frequency might vary depending on factors like the type of filter, indoor air quality, and the amount of dust and debris in your area. If you notice the filter is visibly dirty or clogged, it's a clear sign it needs attention sooner. Regular filter maintenance ensures proper airflow and helps your heat pump perform optimally, keeping your indoor air fresh and comfortable.

You should flush your AC drain line once every three months to keep it clear of debris and buildup. Keeping your AC drain line clean prevents clogs, backups, mold growth, and extra wear on your AC unit. If you live in a humid area or have several furry pets, up your cleaning schedule to once a month.
