Thermostat guide

A thermostat should be easy to read.

Small screens, faint numbers and menus inside menus are a real problem. Our guide shows what each button does, sensible settings for summer and winter, and what to look for if you are choosing a new one.

A visit from us

What happens when we come.

  1. We call ahead

    You'll know who is coming and roughly when.

  2. We take our time

    We listen first, then look at the whole system — not just the part that failed.

  3. We explain it plainly

    What we found and what it costs, before any work starts. No pressure to decide on the spot.

  4. We leave it tidy

    Everything tested, the thermostat set the way you like it, and the floor as we found it.

Questions

Questions we hear often.

Will you tell me the price before you start?

Yes, always. We explain what we found and what it will cost, and you can take your time to decide.

Can you set up my thermostat so it is easy to use?

Yes. We can fit a thermostat with a large display and real buttons, set it the way you like, and leave a printed card with your settings.

What temperature should I set in summer?

Energy.gov suggests about 78 degrees while you are home as an energy-saving starting point. If that feels too warm, set it lower. Comfort and health come first.

Do you look after clubhouses and HOA buildings?

Yes. Community buildings, medical offices, churches and small shops, including maintenance plans with a short written report.

Do you do painting or coatings?

No. Coatings is part of our name. Westmark does heating, ventilation and air conditioning only.

Which areas do you cover?

Sun City, Menifee, Quail Valley, Romoland, Homeland, Perris, Nuevo and Canyon Lake.
