Most homeowners don’t spend much time thinking about their HVAC system until something goes wrong. However, understanding the basics about it helps you better maintain it and ensure that it is operating efficiently. Here are some common questions homeowners ask their residential HVAC contractor.

A Guide to Residential HVAC Systems

Does the size of my system matter?

An HVAC unit needs to be the right size to heat and cool a home efficiently. The location of the home, its square footage, the number and type of windows, and what type of insulation the home has will all play a role in deciding the unit’s size.

If the unit installed is too small, it won’t be able to cool the home to the desired temperature. Too big of a system can lead to higher utility costs, louder operation, and uneven temperatures throughout the home.

How long should my HVAC system last?

The average system is designed to last up to 15 years. Performing regular preventative maintenance will maximize its life span. This includes cleaning out the ducts every three to five years, replacing the air filters at least once every three months, and removing debris around the outdoor condenser.

Have the unit serviced at least once a year by a professional contractor. They recharge the refrigerant, inspect electrical components, and check for wear and tear on mechanical parts.

Should I repair or replace a damaged system?

Repairing a damaged system is often an effective solution. Contractors can fix or replace malfunctioning components so the system works like new again. However, at a certain point, it makes more sense to get a replacement.

If the repair costs exceed 50% of the cost to upgrade to a new unit, it’s time to replace the system. While it will require an upfront investment, newer systems operate much more efficiently than older ones, saving you money on monthly utility bills.

How can I make my system more efficient?

Regularly replacing the air filters and keeping your outdoor condenser free of debris helps maximize airflow and improve efficiency. The insulation around your home also needs to be inspected regularly. If air is getting out through doors or windows, apply weather stripping to bolster the system’s performance.

Installing a smart thermostat also helps. These allow you to program the system to only run during designated times throughout the day, reducing an unnecessary workload.
