Before you call
How often should I schedule AC maintenance?
Once a year is the usual recommendation, ideally just before the cooling season starts. Regular service keeps efficiency up, catches small faults early and helps your equipment last longer.
What size air conditioner does my home need?
Proper sizing depends on square footage, insulation, windows, ceiling height and local climate. We calculate the load rather than guess, because oversized and undersized units both waste energy.
Will you give me an estimate before starting work?
Yes. We explain the problem and the options first so you know the cost before any work begins.
Should I repair or replace my system?
As a rule of thumb, equipment past 10 to 15 years that needs frequent repairs or still uses older refrigerant is usually a better candidate for replacement. Newer systems with a minor fault are normally worth repairing.
Why should I avoid DIY AC repairs?
Cooling systems combine high-voltage electrical parts with regulated refrigerant. Mistakes can hurt you, damage the equipment or void a warranty, so it is safest to leave repairs to a trained technician.
What can I do to lower my cooling costs?
Keep filters clean, seal air leaks, use a programmable thermostat and book a yearly tune-up. If your equipment is old, an efficient replacement can make a bigger difference.
