Good afternoon, Linda. I’m Ethan from Apex Home Services. I’m here to inspect your heating system.

Hello, Ethan. Thank you for coming on short notice. The furnace has been making strange noises.

Let’s start in the basement. Could you show me where the furnace is located?

Sure. Follow me down the hall. It’s the unit with the red warning light blinking.

I see. The blinking red light indicates a pressure issue. I’ll check the pressure gauge first.

Potentially. It could be a faulty pressure relief valve or debris in the line.

How long does this inspection usually take?

About twenty minutes for diagnostics. If parts are needed, repairs may take up to two hours.

Okay. Please go ahead with the diagnostics.

I’m going to shut off the power before examining internal components.

Is it safe to remain in the house during the inspection?

Yes. The system will be off briefly. You won’t feel anything unfamiliar.

The pressure gauge reads 25 psi, which is below the normal range of 30–35 psi.

Possible causes are a leaking valve, air in the lines, or wear on the heat exchanger.

Can you fix it today if you find the faulty part?

I carry common replacement valves. If that’s the issue, I can install it now.

That would be ideal. What about cleaning the air filter?

I’ll clean or replace the filter as part of the service. It improves airflow and efficiency.

Great. Do I need to prepare anything upstairs while you work?

Just keep doors open to ensure proper ventilation. I’ll let you know when I need access to other areas.

You’re welcome. I’ll start with the valve check now.
