Question 1

How do I know if I should repair or replace my HVAC system?

Accepted Answer

The 50% rule is a useful starting point: if a repair approaches half the scope of a replacement and the system is past 12–15 years, replacement usually wins. Other replacement signals: phased-out refrigerant, frequent breakdowns, uneven temperatures, and rising energy bills. A contractor can assess both paths in one visit.

Question 2

What size HVAC system does my home need?

Accepted Answer

Proper sizing requires a Manual J load calculation based on square footage, insulation, windows, ceiling height, and local climate — not just tonnage per square foot. Oversized systems short-cycle, waste energy, and leave humidity behind. Any contractor who sizes by rule of thumb alone is cutting corners.

Question 3

How long does a full HVAC replacement take?

Accepted Answer

Most residential changeouts take one to two days: removing old equipment, setting the new condenser and air handler or furnace, connecting refrigerant lines and ductwork, then testing and commissioning. Complex ductwork modifications can extend the timeline.

Question 4

What is SEER2 and does it matter?

Accepted Answer

SEER2 is the current efficiency rating standard for air conditioners and heat pumps — higher means less electricity per unit of cooling. In hot climates the savings add up fast; in mild climates the payback is slower. Your contractor can explain which efficiency tier fits your climate and usage.

Question 5

Will a new system require ductwork changes?

Accepted Answer

Sometimes. Undersized, leaky, or poorly designed ductwork can cripple even a perfect new system. A thorough contractor inspects your ducts during the estimate and tells you honestly whether modifications are needed for the new equipment to perform.

Question 6

Are installation estimates really free?
