Before you call
What are your business hours?
We are open Mon–Sun 7:00am – 8:00pm. Call the number on this page to book a visit or ask a question.
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.
Why is my AC running but not cooling?
Common causes include a dirty filter, a frozen evaporator coil, low refrigerant or a failing capacitor or fan motor. A technician can pinpoint the cause quickly and tell you what the fix involves.
How do I know if my air conditioner needs repair?
Warm air from the vents, weak airflow, strange noises, water around the unit or a sudden jump in your energy bill are all signs. If your system is not cooling the way it used to, have a technician take a look before it gets worse.
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.
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.
