Payne AC Installation

Most HVAC systems last 15-20 years with proper maintenance. Air conditioners and heat pumps typically last 15-20 years, while furnaces can last 20-30 years. Consider replacement if your system is over 15 years old and requiring frequent repairs, or if repair costs exceed 50% of a new system's price.

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.

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.
