BEFORE YOU BLAME THE FURNACE… CHECK THE THERMOSTAT. 🌡️

Is your home not heating the way it should?

Start with the basics:

👉 Is the thermostat set to HEAT?
👉 Is the temperature set above the current room temperature?
👉 Are the batteries good?
👉 Is the furnace actually turning on?
👉 Is the filter clean?

If you’ve checked the basics and something still isn’t right, it’s time to call the professionals.

TCS Mechanical is ready to help keep you comfortable this fall and winter.

YOUR FURNACE FILTER MATTERS. 🧰

A dirty filter can restrict airflow and make your HVAC system work harder.

Before heating season gets into full swing:

✔️ Check your filter
✔️ Replace it if it’s dirty
✔️ Make sure you have the correct size
✔️ Keep extra filters on hand

Want to make filter changes easier?

Ask TCS Mechanical about getting filters for a year.

THAT FIRST FURNACE RUN OF THE SEASON…

You turn the thermostat up.

You hear the furnace kick on.

You wait…

…and hope everything works. 😂

Don’t leave your first furnace start-up to chance!

If your furnace has been sitting unused since spring, October is a great time to have it checked before you really need it.

Get ahead of winter. Stay comfortable all season.

🧰 WHEN WAS THE LAST TIME YOU CHANGED YOUR HVAC FILTER?

Be honest. 😂

A dirty filter can restrict airflow and make your HVAC system work harder.

September is a great time to check it before heading into heating season.

👉 Pull it out.
👉 Take a look.
👉 If it’s dirty, replace it.

And if your HVAC system isn’t operating the way it should, give TCS Mechanical a call.
