Frequently Asked Questions

Is it worth upgrading to a smart thermostat?
Smart thermostats typically save 10-15% on heating and cooling costs by learning your schedule and preferences. They offer remote control via smartphone, energy usage reports, and integration with smart home systems. Most homeowners recoup the investment within 1-2 years through energy savings.
What size AC do I need for my home?
AC sizing depends on square footage, ceiling height, insulation, windows, climate zone, and more. Rough estimates suggest 20 BTU per square foot, but proper sizing requires a Manual J load calculation. An oversized AC wastes energy and causes humidity problems; undersized units can't keep up.
How long does an air conditioner last?
A well-maintained central air conditioner typically lasts 15-20 years. Factors affecting lifespan include maintenance frequency, usage patterns, local climate, installation quality, and brand. Regular tune-ups, filter changes, and addressing repairs promptly can extend your AC's life.
What is a SEER rating?
SEER (Seasonal Energy Efficiency Ratio) measures AC cooling efficiency. Higher SEER means lower operating costs. Minimum SEER is currently 14-15 depending on region. High-efficiency units range from 16-26+ SEER. A 16 SEER unit uses about 13% less energy than a 14 SEER unit.
