How to hire a hvac contractor in Cary

1

Ask for a load calculation (Manual J) before any replacement, not a guess by square footage.

2

Compare SEER2 ratings and the warranty on the compressor, not just the sticker price.

3

Check that the company is licensed and that its technicians are NATE certified or equivalent.

4

A good tune-up includes refrigerant pressures, airflow and electrical checks, not a filter swap.

Good to know

HVAC Contractor questions, answered

How long does an air conditioner last?

About 12 to 15 years in hot climates with regular maintenance. Frequent repairs after year 10 usually mean replacement is the better buy.

Repair or replace?

A common rule: if the repair costs more than half the price of a new system and the unit is over 10 years old, replace it.

How often should filters be changed?

Every 1 to 3 months for standard 1-inch filters, more often with pets or allergies. Thicker media filters can go 6 to 12 months.
