Just because your air conditioner is idle during the winter months doesn’t mean you should ignore it. How you maintain your A/C during off-season can actually make a big difference in its performance, energy efficiency, and lifespan.
At Efficient Systems, proudly serving Beaumont, Winnie, Lumberton, and nearby communities, we’ve outlined the most common off-season mistakes — and how to avoid them — to ensure your system is ready to go when the heat returns.
1. Ignoring the Outdoor Unit
Mistake: Letting debris like leaves, dirt, and grass build up around the outdoor condenser unit.
Why it matters: All that buildup can choke airflow, hurt components, and decrease efficiency when the unit comes back on.
2. Not Covering the Unit
Error: Exposing your outdoor unit to the elements for the entire winter season.
Why it matters: Rain, snow, and dropped debris lead to corrosion, rust, and physical harm.
Expert Tip: Employ a porous A/C cover that excludes debris but escapes moisture, avoiding mold and rust.
3. Failing to Change Air Filters
Mistake: Failing to replace the air filter on the grounds that the A/C is not in service.
Why it matters: Dust and allergens continue circulating, leading to indoor air quality issues and possible clogging of your system.
Expert Tip: Replace your air filter every 1–3 months, even in off-peak seasons.
4. Postponing Preventive Maintenance
Why it matters: Small problems have time to develop and cause costly repairs or failures when you need cold air the most.
Expert Tip: Book a preventive maintenance visit during the off-season to detect and resolve issues ahead of time.
5. Failing to Insulate Refrigerant Lines
Error: Failing to check damaged or missing insulation on refrigerant lines.
Why it matters: Inefficient insulation decreases performance and adds extra stress on your system.
Pro Tip: Check the lines and replace deteriorating insulation with foam sleeves or insulation tape to safeguard your system.
6. Failing to Adjust the Thermostat
Error: Having your thermostat on “cool” or keeping ineffective temperature settings when it’s cold outside.
Why it matters: This can result in excess system operation and wasted energy.
Expert Tip: Turn your thermostat to heat mode and set it for seasonal energy savings.
7. Putting Off a System Replacement
Mistake: Waiting until peak season to replace an old or inefficient system.
Why it matters: Waiting until peak season can result in higher expenses and longer installation wait times.
Expert Tip: Off-season is the best time to upgrade. Use discounts and flexible scheduling to your advantage when demand is low.
