Frequently Asked Questions About HVAC in Harrison

Get answers to common questions about hvac services in Harrison, Montana.

1What are the most important HVAC considerations for my home given Harrison's climate?

Harrison's climate, with cold, dry winters and warm, dry summers, demands a system capable of handling extreme temperature swings. A high-efficiency furnace (preferably 90% AFUE or higher) is crucial for winter, while a properly sized central air conditioner or heat pump is key for summer comfort. Given the dry air, integrating a whole-house humidifier in winter and ensuring proper ventilation year-round are highly recommended local considerations.

2When is the best time to schedule HVAC maintenance or installation in Harrison?

Schedule furnace maintenance or replacement in late summer or early fall (August-September), and air conditioner service in late spring (April-May), well before peak seasonal demand. For installations, these shoulder seasons offer better availability and potential off-season pricing. Avoid the deep winter freeze or summer heatwaves, as HVAC companies are at their busiest with emergency repairs, leading to longer wait times.

3Are there any local regulations or rebates in Montana I should know about when replacing my HVAC system?

While Harrison follows Montana state codes, specific local county permits may be required for major installations. Crucially, check for available rebates from Northwestern Energy, Montana's primary utility, which often offers incentives for upgrading to high-efficiency furnaces, heat pumps, and air conditioners. Your local HVAC contractor should be familiar with both the permitting process and current utility rebate programs.

4My furnace is old. Should I repair it or replace it, especially with our harsh winters?

This depends on the furnace's age, repair cost, and efficiency. If your furnace is over 15 years old, requires a costly repair (exceeding 50% of replacement cost), or has an AFUE rating below 80%, replacement is often more cost-effective and reliable for Harrison winters. A new, high-efficiency model will provide greater comfort, improved safety, and significant savings on your heating bills, which is critical given our long heating season.
