Frequently Asked Questions

Got questions? We’ve got answers
How often should I service my air conditioning unit?
We recommend servicing your AC unit at least once a year, ideally in spring before the cooling season begins. Regular maintenance helps prevent breakdowns, improves efficiency, and extends the life of your system.
The right size depends on your home’s square footage, insulation, ceiling height, and other factors. Our technicians will perform a load calculation to determine the perfect size for optimal efficiency and comfort.
Most residential AC installations take 4–8 hours, depending on the complexity. We’ll provide a specific timeline during your consultation and work efficiently to minimize disruption to your home.
Yes! We offer flexible financing options to make your AC upgrade affordable. Ask about our current promotional rates and payment plans when you call.
If your AC is less than 10 years old and the repair cost is less than half the replacement cost, repair is usually the best option. For older units with major issues, replacement often makes more financial sense long-term.
Absolutely! We offer 24/7 emergency AC service because we know that breakdowns don’t wait for business hours. Call us anytime for urgent cooling needs.
