Frequently Asked Questions About HVAC in Monmouth

Get answers to common questions about hvac services in Monmouth, Illinois.

1What is the best time of year to replace my HVAC system in Monmouth?

The ideal times are during the mild shoulder seasons of spring (April-May) or fall (September-October). This avoids the peak summer demand for AC and winter demand for furnace repairs in Monmouth's humid continental climate, potentially leading to better scheduling and pricing. It also ensures your system is ready before the extreme temperatures of our Illinois summers and winters hit.

2Are there any local rebates or incentives for upgrading to a high-efficiency HVAC system in Illinois?

Yes, Illinois homeowners can benefit from both federal tax credits for qualifying high-efficiency systems and local utility incentives. For example, Ameren Illinois often offers rebates for installing ENERGY STAR® certified heat pumps or furnaces. It's crucial to consult with your local Monmouth HVAC provider, as they are best informed on the current, specific rebates available through our area's utility providers.

3How often should I schedule professional HVAC maintenance in Monmouth's climate?

You should schedule professional maintenance twice a year: once in the spring for your air conditioning system and once in the fall for your furnace. Monmouth experiences high humidity in summer and freezing temperatures in winter, putting significant strain on both systems. This bi-annual service ensures optimal efficiency, prevents mid-season breakdowns, and extends the lifespan of your equipment.

4What should I look for when choosing a local Monmouth HVAC contractor?

Always verify that the contractor is licensed, bonded, and insured to work in Illinois. Look for established local companies with strong community reputations, as they understand the specific installation and service needs for our older homes and climate. Check for certifications from manufacturers (like Carrier, Trane, etc.) and always ask for detailed, written estimates that include labor, parts, and warranty information.

5My furnace is old. Should I repair it or replace it as a Monmouth homeowner?

This depends on the age, repair cost, and efficiency of your current system. If your furnace is over 15 years old, requires a repair costing more than half the price of a new unit, or has a low AFUE rating (below 80%), replacement is often more cost-effective. Given Monmouth's cold winters, a new, high-efficiency furnace will provide more reliable heat and significantly lower your heating bills.
