We're Here To Share The Top Three Reasons Why AC Units Fail In The Fall

Temperature Fluctuations - The Tricky Treat of Fall Weather

Fall weather can be unpredictable, with temperature fluctuations ranging from warm afternoons to chilly nights. These temperature changes can cause your AC unit to work harder than usual, leading to increased wear and tear on the system. Additionally, switching your thermostat back and forth between heating and cooling can cause confusion for your AC unit, leading to malfunctions or breakdowns. If you’re experiencing issues with your ductless AC during the fall, it’s best to call the Monterey Peninsula Sheet Metal & Heating professionals for reliable and detailed ductless AC repair in Monterey, CA. We will diagnose the problem promptly and provide efficient and effective solutions to keep your AC unit running optimally.

Neglected Maintenance

It’s easy to forget about your AC unit during the fall and winter months, but neglecting maintenance can lead to more significant problems come next summer when you need it again. For example, dirty air filters can restrict airflow, causing your unit to work harder and consume more energy, while clogged condensate drains can lead to water damage and mold growth. Worn-out parts can also cause your AC to malfunction or break down entirely. Regular maintenance, including cleaning or replacing air filters, checking and cleaning condensate drains, and inspecting and repairing worn-out parts, can prevent these issues and extend the life of your AC unit.


As the temperature drops outside, critters like mice and squirrels look for warm places to nest. Unfortunately, your outdoor AC unit can be a cozy spot for these furry friends. Rodents can cause significant damage to your unit’s electrical wiring and other components, leading to a malfunction or complete breakdown. Some common signs of rodent damage include chewed wires, debris inside the unit, and strange noises coming from the unit. If you suspect critters have made a home in your AC unit, causing it to malfunction, it’s essential to call our professionals at Monterey, CA, for emergency AC repair. We can safely remove critters and repair any damage they may have caused, preventing further damage and ensuring your AC unit continues functioning correctly.

Don’t let the fall season fool you into thinking your AC unit can be ignored. By staying proactive and caring for your AC unit, you can ensure it’s ready to go when the summer heat returns.
