HVAC Accessories

When you’re repairing or replacing your current HVAC unit, you might consider adding on a few accessories.

When your HVAC technician comes out to your house to look at your HVAC unit, he may mention a few accessories that can make your HVAC unit perform at its best. Here are a few of the most common HVAC accessories that you might come across:

Surge Protector

You probably have a surge protector on your computer and TV, but putting one on your HVAC unit might not have occurred to you.

Your HVAC unit is one of the most expensive pieces of equipment you’ll buy for your home, and if you don’t have a surge protector on it, your HVAC unit is susceptible to voltage spikes, power surges and lightning strikes.

An inexpensive HVAC surge protector will protect your unit’s motors and compressors.

UV Light

Ultraviolet lights, the same that nail solons use to cure nail polish quickly, can also be installed into your ductwork to keep your ducts clear of mold and bacteria.

If you’ve ever had mold in your house, there’s a good chance that it is also in your HVAC system. Have a professional inspect your ductwork and install a UV light to prevent the growth of mold and bacteria that may affect your air quality.

Thermostat

At the most basic level, a thermostat is an on and off switch for your HVAC unit, but if you want to get more out of your thermostat, an upgrade might be in order. New thermostats have great features that can save you money on your utility bills every month.

Digital thermostats are more accurate than manual ones, and some newer units even have Wi-Fi access, meaning you can use your phone to control your thermostat from anywhere in the world with an internet connection.

Float Switch

Over time, various obstructions can cause moisture to accumulate in your HVAC unit, causing your main drain to backup.

To avoid water damage to your home and potential microbial growth in your HVAC unit, consider having a technician install a float switch.

In case of a backup in your main drain, your float switch will deactivate your HVAC’s compressor, preventing your drain pan from overflowing and stopping the production of moisture in your HVAC unit.

Contactor

Your contactor controls the flow of electricity in your HVAC unit. The contactor is exposed to high voltages, and over time, the contactor begins to deteriorate.

Eventually, it will become pitted. This is normal wear and tear, but it should be replaced so that your HVAC unit can function efficiently.

Capacitor

Capacitors function like batteries in your HVAC unit. Like the battery in your car or cell phone, capacitors will eventually be unable to hold a charge. When that happens, you’ll need to replace them.

The capacitors in HVAC units jump-start the compressor, blower motor and outside fan, so if a capacitor fails, your unit will begin to fail.

If a capacitor is not replaced quickly, it will cause undue wear and tear on your HVAC unit, most notably the motor to which it is attached. A failed capacitor could cause serious damage to the unit and could result in a costly repair.
