Start with the heating or cooling problem affecting your home.

Note what changed, which rooms are affected, and any unusual sounds, odors, error codes, or recent service.

01

If the AC runs but does not cool

Confirm that the thermostat is set to cooling, check the filter according to the manufacturer’s instructions, and make sure supply registers are open and unobstructed. Note weak airflow, ice, unusual water, odors, noises, error codes, or repeated cycling so you can describe the problem clearly when you call.

Do not open equipment panels, touch electrical components, or attempt to add refrigerant. Keep away from the system if you notice smoke, sparking, a burning odor, damaged wiring, or water near energized equipment.

02

Prepare the basic system details

Note whether the issue involves cooling, heating, airflow, unusual noise, short cycling, or a system that will not start. If available, record the equipment type, approximate age, and any displayed error code.

03

Describe what changed

Explain when the problem began, whether it affects the entire home or particular rooms, and whether the system has recently received maintenance or repairs.

04

Review the proposed service scope

Ask what diagnosis, parts, labor, permits, warranties, and follow-up are included. Request written pricing and confirm whether the recommendation is for repair, maintenance, or replacement before authorizing work.

What can change an HVAC estimate?
  • Whether the visit covers diagnosis only or includes the repair.
  • The part, labor, refrigerant, permit, or equipment included in the proposed work.
  • System type, equipment access, age, and whether compatible parts are readily available.
  • Whether the recommendation is maintenance, repair, or full replacement.

Ask for written pricing that separates the diagnosis from the proposed work and explains what could change the total.
