Johnstone Supply | Top-Rated HVAC Repair in Idaho Falls, ID

We carry a range of products to improve heating efficiency. For furnaces, consider upgrading to a high-efficiency air filter, a new flame sensor, or a programmable thermostat to better manage runtime. For heat pumps, ensuring your reversing valve and defrost controls are functioning correctly is key. Our team can help you identify the right components for your specific system to maximize heat output and reduce wasted energy.

For the mineral deposits and debris common in our area, we recommend a no-rinse coil cleaner specifically designed for aluminum fins, a gentle fin comb to straighten any bent fins, and a coil cleaning brush. It's also a good idea to check and have replacement capacitor(s) on hand, as a struggling dirty coil can overwork and damage them. We can provide the right products and basic guidance for safe, effective cleaning.

Absolutely. We specialize in sourcing parts for a wide variety of HVAC systems, including many older models common in Idaho Falls homes. Whether you need a specific blower motor, control board, gas valve, or refrigerant metering device, bring in the model and serial numbers. Our extensive inventory and supplier network make us a reliable resource for keeping all types of systems running smoothly and efficiently.
