Heating and Air Conditioning questions, answered by experts

If your drain line is clogged, your AC might stop cooling, shut down, or refuse to turn on at all. Otherwise, you might see your AC leaking water, find standing water or water damage near the unit, or notice a musty smell coming out of your air conditioner or vents.

Absolutely! You can seriously improve the overall value of your home by maintaining high-quality, compatible systems for heating and cooling. Potential buyers will love not having to worry about getting a new HVAC unit for 15 to 20 years and will pay more for it. For maximum efficiency and cost savings, replacing the furnace and air conditioner at the same time, when possible, gives you (and potential future buyers) reliable comfort and modern convenience.

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. 

Some states require special licenses for HVAC professionals, but most don’t. However, even if there is no state requirement for HVAC licensing, local requirements might exist. It’s always a good idea to check if HVAC technicians need to be licensed in your area and then Angi’s contractor license lookup tool to confirm that the contractor you’re hiring holds the necessary licenses. Additionally, you should always ensure the company you’re hiring is fully insured to avoid potential lawsuits if a technician gets injured on your property.

To extend your HVAC system’s lifespan, it’s crucial to keep up with maintenance. This includes changing filters and thermostat batteries, keeping the outside unit clean and clear of clutter, and lubricating moving parts. Watch out for leaks, mold buildup, and blockages to ensure your unit stays in good working order. Spotting these issues early can be the difference between a simple, wallet-friendly repair and an expensive replacement.
