How often should I check my furnace filter?

Did you know that a dirty filter can restrict airflow and cut down on the efficiency of your furnace and A/C unit? Check your filter at least 2 times a year, before the heating season and again before the cooling season.

Why is my heater making popping noises?

When your water heater is making popping noises, it is heating up the sediment in the bottom of the tank. The sediment decreases the amount of hot water you actually are receiving. It may be a good time to have the water heater replaced.

How can I make my A/C condenser more efficient?

Did you know that keeping your A/C condenser clear of landscaping vegetation will keep it running more efficiently? Remember to trim away bushes and overgrown trees around your condenser.

How can I save water?

By installing low flow fixtures you will use less water in the long run.

Is it possible to have hot water at my sink quickly?

Yes! Install an affordable circulating pump kit to serve your whole home.
