Frequently Asked Questions
What size air conditioner does my home need?
Proper sizing depends on a load calculation, not a rule of thumb. We measure your home so your system is neither undersized nor oversized, both hurt comfort and efficiency.
How often should I change my filter?
Most homes do well changing filters every one to three months. We can recommend the right schedule and filter for your system.
Central air or ductless for my home?
Central air suits homes with good ductwork; ductless is ideal for additions or homes without ducts. We help you choose based on your home and budget.
