FAQs
Why does my furnace keep turning on and off?
A dirty blower wheel can clog up your system, causing your furnace to short-cycle. The first step to troubleshooting is always to change your filters. If that doesn’t work, an HVAC technician will check for a faulty thermostat and worn wiring.
Are tankless water heaters worth it?
Tankless water heaters are ultra-efficient, eco-friendly, and durable. They’re more expensive than traditional systems upfront but bring long-term savings through reduced maintenance needs and a longer life span. They also provide on-demand heating, so you’ll never need to have a cold shower again.
