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 before the summer season. Regular maintenance ensures optimal performance, prevents breakdowns, and can extend the lifespan of your system.
What size air conditioner do I need for my home?
The right size depends on factors like your home's square footage, ceiling height, insulation, and layout. Our team offers free assessments to determine the perfect unit for your space—ensuring energy efficiency and consistent comfort.
Why is my AC blowing warm air?
Warm air could be caused by low refrigerant levels, a dirty air filter, a thermostat issue, or even a failing compressor. It's best to schedule a diagnostic visit so we can pinpoint and fix the issue quickly.
How long does installation take?
Most standard residential AC installations take 4 to 8 hours, depending on system complexity and home layout. We’ll give you a time estimate before we start and keep you informed throughout the process.
Do you offer warranties or guarantees on your work?
Yes! All of our installations and repairs come with a warranty for parts and labor. We also stand behind our work with a satisfaction guarantee—your comfort is our top priority.
