What is HVAC?

HVAC means heat, vent, and air cool. For 2,000 sq ft, you need a good mix. It heats when cold. It cools when hot. It does not waste power. Most have a furnace or pump for heat. They have AC or a pump for cooling. Ducts send air around.

Why 2,000 sq ft? It is like many homes. Three or four beds. Not too big. Systems need 3 to 4 tons. One ton is 12,000 BTU per hour. BTU is how much cool. Too small, it works hard. Breaks fast. Too big, it turns on and off. Wastes energy.

Split systems are common. Inside part. Outside part. They work together. Fit old homes easily. No ducts? Use ductless. It cools rooms one by one.

People with these homes want a good deal. Not too cheap. Not too fancy. Look up the HVAC replacement cost 2000 sq ft home. Plan for better power use.
