Preventative HVAC Tips
Your HVAC (Heating, Ventilating, and Air Conditioning) system is a pretty important part of your home, regardless of whether it’s at the forefront of your mind all that often. Like other aspects of your home, your plumbing and electrical wiring are just supposed to work, and your HVAC system usually isn’t any different. Unlike your electrical wiring and plumbing, there are steps you can take to actively protect your HVAC system from some uncertainty later on.
Like any other appliance in your home, your HVAC system requires electricity to work. However, one of the main differences between your HVAC system and, say, your TV (other than their obviously different designs and intents) is that a lot of people put a surge protector on their televisions. The same, unfortunately, cannot be said for your HVAC system.
Hooking up a surge protector can protect your valuable and somewhat delicate HVAC components just as well as it can your television in the event of a power outage, or more specifically, the power coming back on afterward.
Why Power Surges Are A Real Risk In Southern California
Power surges happen for a lot of reasons beyond a simple outage. Rolling brownouts during heat waves, utility grid switching, lightning during rare desert storms, and even large appliances like air conditioners and pool pumps cycling on and off can all send a sudden spike of voltage through your home’s wiring. In Murrieta, San Marcos, Orange and the rest of Southern California, summer heat waves push the electrical grid hard, which makes voltage fluctuations more common right when your HVAC system is working its hardest to keep your home cool. Every surge, even a small one, puts stress on the sensitive circuit boards and electronic controls inside a modern air conditioner, heat pump or furnace.
Other Simple Ways To Protect Your HVAC System
A whole-house surge protector is one of the easiest upgrades you can make, but it works best as part of a broader approach to protecting your system. Consider these additional steps:
- Schedule routine maintenance. Regular tune-ups let a technician catch worn capacitors, loose electrical connections and refrigerant issues before they turn into a breakdown during a heat wave.
- Change or clean air filters on schedule. A clogged filter forces your system to work harder, which increases wear and energy use.
- Keep the outdoor unit clear. Trim back plants, leaves and debris so air can flow freely around your condenser or heat pump.
- Install a whole-house surge protector at your electrical panel in addition to any point-of-use protection, since this guards your HVAC system along with your other major appliances.
- Consider a smart thermostat. Many models can alert you to unusual cycling patterns that may indicate an electrical issue.
- Enroll in a maintenance plan so inspections happen automatically instead of being easy to forget.
Signs Your HVAC System May Have Been Affected By A Power Surge
Not every surge causes immediate, obvious damage. Watch for these warning signs after a storm, outage or brownout:
- The system won’t turn on or trips the breaker repeatedly
- Strange burning smells coming from the vents or outdoor unit
- A thermostat that stops responding or displays an error code
- Unusual noises from the compressor or blower motor
- Uneven heating or cooling that wasn’t a problem before the outage
If you notice any of these symptoms, it’s best to have a professional HVAC repair technician inspect the system rather than continuing to run it, since a damaged circuit board can sometimes cause further harm the longer it operates.
When To Call A Professional
A surge protector is something most homeowners can have installed without much hassle, but it should still be wired in by a licensed professional to make sure it is properly grounded and sized for your system. It is also worth having an electrician or HVAC technician evaluate your home’s overall electrical setup, especially in older homes where wiring may not be ideal for today’s higher-efficiency HVAC equipment. If you are already noticing flickering lights, frequent breaker trips, or an HVAC system that seems to be aging faster than it should, that is a good signal to schedule a checkup rather than wait for a full breakdown. Pairing surge protection with a maintenance plan gives your system the best chance of running reliably through the demanding Southern California summer and the cooler winter months alike.
If your system is older or has already been through a few rough surges, it may also be worth discussing AC installation options with a technician, since replacing an aging unit can sometimes be more cost effective than continuing to repair surge-related damage. For homes dealing with frequent furnace issues, furnace repair services can also help diagnose whether an electrical event is to blame.
Frequently Asked Questions
Do I need a surge protector if I already have one on my TV and computer?
Yes. Point-of-use surge protectors for electronics do not protect your HVAC system, which is wired directly into your home’s electrical panel. A whole-house surge protector installed at the panel is the best way to guard your furnace, air conditioner or heat pump.
Can a power surge really damage my air conditioner or furnace?
Yes. Modern HVAC systems rely on circuit boards and electronic controls that are sensitive to voltage spikes. A single strong surge can fry a control board, while repeated smaller surges can shorten the overall lifespan of the equipment.
How much does a whole-house surge protector cost to install?
Costs vary depending on your electrical panel and home setup, so it’s best to get a quote from a licensed professional who can evaluate your specific system and recommend the right size of protection.
