HVAC

You rely on your HVAC system to keep your home comfortable when conditions outside are less than desirable. However, the weather outside can take a toll on its components. We experience intense spring thunderstorms, blistering summer heatwaves, and winter snow and subfreezing temperatures. Mother Nature puts your heating and cooling system through the ringer in a variety of ways. Here are eight effects that extreme weather can have on your HVAC system, along with tips for preventing problems.

1. Increased Energy Usage

It’s no surprise that extreme weather can lead to a spike in your energy bill. When the temperatures rise high or dip low, your HVAC runs more and uses more energy. The good news is that there are several steps you can take to reduce the amount of excess energy used.

Turning your thermostat down a few degrees in cold weather or up a few degrees during heat waves can significantly reduce your energy usage. Adding humidity control to your system can help you stay just as comfortable while giving your HVAC a break. Additionally, we can install attic or ceiling fans. Ceiling fans can create a cooling breeze in summer and help distribute heat more effectively in winter.

Here are some other steps you can take to reduce excess energy usage during extreme weather:

  • Install extra insulation
  • Keep doors and windows closed
  • Block drafts
  • Avoid using the stove during hot weather
  • Use your ceiling fans

2. Debris and Hail Damage

Severe storms can batter your outdoor compressor unit with high winds, hail, and debris. Heavy rains can also cause flooding, especially if your unit is located in a low-lying area. An annual tune-up and inspection can help determine if your HVAC is at risk of storm damage. If you don’t use a heat pump in winter, a cover for your outdoor compressor can keep snow and debris from piling up.

If you use a heat pump, it’s essential to remove any buildup of leaves, sticks, and other debris on a regular basis. Snow and ice accumulation, as well as debris blown in from severe storms, can block airflow and prevent your outdoor compressor from working. Trim shrubs and overhanging branches to minimize the accumulation of leaves and debris. Fencing around the outdoor unit can prevent debris and snow buildup around the unit. It’s also important to check for anything that might restrict airflow to your HVAC as soon as the extreme weather event is over.

3. Problems With Refrigerant

Refrigerant pressure can increase when outdoor temperatures rise, and high pressure in the lines can lead to breaks and leaks. These leaks would decrease refrigerant levels, resulting in decreased performance and efficiency. When your HVAC system can’t access enough refrigerant, efficiency is reduced. The system must work harder to maintain the set temperature, resulting in increased energy use and potentially shorter system lifespan. Checking refrigerant levels and fixing leaky refrigerant lines are important parts of regular professional maintenance.

4. Accelerated Wear and Tear

Extreme temperatures require your HVAC system to work harder to maintain a comfortable home. Working overtime puts extra stress on components and causes them to wear out early. Older systems are especially vulnerable to damage from increased mechanical strain. Remember to get a tune-up before bad weather hits to make sure your system can hold up, especially if your system is aging. The last thing you want is for your heating or air conditioning to go out during extreme temperatures.

5. Components Freezing Up

The coils in your indoor air handler can freeze in summer. When this happens, the system can’t remove heat from the air, and you get warm air from your vents. Frozen coils are usually caused by low airflow or low refrigerant. Change the air filter every two to three months to maintain sufficient airflow or more often if you have pets. As mentioned above, low refrigerant is almost always caused by a leak in the system. If you have a newer system, we can repair the leak and then refill the refrigerant. If you have an older system, a replacement may be the best option.

If you use a heat pump for heating, extreme cold can cause outside refrigerant coils to freeze. Cold-climate heat pumps often feature heat strips or auxiliary heating methods to supplement heating when temperatures drop. Some also have a defrost cycle.

6. Overheating and Shutdowns

Sweltering heat combined with prolonged operation can cause your HVAC to overheat and shut down. This can damage components, leading to costly repairs or replacement; therefore, it’s essential to shut the system off if you suspect overheating. Signs of overheating include fluctuating temperatures, unusual noises, and ice on the coils or ductwork. You can help prevent overheating by keeping up with regular maintenance and using a shade to protect your outdoor unit from heat and sunlight.

7. Mold and Mildew Growth

Heavy rainfall and high humidity often bring mold and mildew growth in your ductwork. Mold and mildew are problems that often go unnoticed until they become severe. Signs of mold or mildew in your ducts include unpleasant, musty odors, increased respiratory symptoms, and patches of mold growth around vents.

Because mold and mildew can compromise indoor air quality and make your family sick, prevention is important. Regular duct cleaning removes mold before it can grow. Maintenance tasks, like changing air filters and inspecting drain pans and lines, are another important step. If your home has an ongoing humidity problem, you may need to consider solutions like dehumidifiers, exhaust fans, or ductwork sealing. Incorporating UV light air purification may also help.

8. Rust and Water Damage

Rust and water damage can destroy your HVAC system. If heavy rains and thunderstorms frequently submerge your outdoor compressor unit, it may have significant damage inside. Because most homeowners don’t notice this damage until it’s too late, annual or seasonal inspections are essential.

Although water damage from flooding is more obvious and catastrophic, excess humidity and condensation can also damage your HVAC over time. If you notice visible rust, pools of water, or unusual noises during operation, your HVAC system may benefit from preventive measures. These can include a condensation pump, a drain line, or a safety float switch that powers off the unit when condensation builds up.
