Frequently Asked Questions (FAQs)
How often should I service my air conditioner?
We strongly recommend professional AC servicing every year or two. This helps optimize performance, catch minor issues, and extend your system’s lifespan. Monthly filter checks also help keep airflow clear and efficient.
Why is my AC leaking water or freezing up?
Water around your indoor unit often indicates a clogged condensate drain or frozen evaporator coil, typically caused by low refrigerant or poor airflow. Ice forms, melts, then leaks water. We can clean the line, check refrigerant levels, and restore proper airflow.
What size AC unit do I need for my home?
Sizing isn’t about square footage alone. We also evaluate other factors such as insulation, windows, layout, and shading. Proper sizing ensures efficient cooling without short-cycling or wasting energy.
Why isn’t my air conditioner cooling properly?
Common issues include dirty filters, low refrigerant, frozen coils, duct issues, or broken compressors. Start by replacing the filter and clearing debris around the condenser. Persistent problems require professional diagnosis.
How long do air conditioners typically last?
With regular maintenance, central AC systems last 15-20 years, and well-maintained ductless mini-splits can last up to 20 years. Factors like climate, frequency of use, and upkeep significantly impact longevity.
Can proper maintenance save me money?
Absolutely! Routine maintenance can significantly reduce repair costs over your system’s lifetime. It improves efficiency, lowers energy bills, and helps prevents breakdowns.
What temperature should I set my thermostat for comfort and savings?
We recommend setting your thermostat around 74-76°F during summer. Each degree higher can noticeably reduce energy use. Proper thermostat placement away from direct sunlight or drafts also helps your system run accurately.
