Turning your A/C completely off while you're away might seem like the best way to save energy, but that's not always the case.

Like Celsius mentioned, try setting your thermostat a few degrees higher while you're at work. Your home will stay at a reasonable temperature, and your system won't have to work overtime to cool the house when you get back.

Another tankless system back up and running! 🔧

For this repair, our team replaced the tankless heat exchanger along with the wiring harness to get the unit operating properly again.

This photo was taken after the repair, with the system running as it should. Sometimes the right repair can help keep your existing equipment going without needing a full replacement.

Update 2026-05-28: Had another visit from Samir, this time to repair our A/C. He was quick, friendly, and got everything up and running in no time. I'm very happy to be on the maintenance plan with A1.”

Your A/C needs to breathe!

This unit stopped working because it was clogged with dirt and debris, making it harder to release heat. When that happens, the compressor and fan have to work overtime, putting extra strain on your system and increasing the risk of costly repairs.

Annual maintenance and keeping your outdoor unit clean are two of the best ways to improve efficiency and extend the life of your A/C.
