Industry Specific FAQs

Furnace Maintenance & Replacement

How often should I schedule furnace maintenance in Morris, IL?

For reliable winter performance, we recommend annual maintenance on your furnace—particularly before winter begins. Regular tune‑ups improve efficiency, help avoid breakdowns, and extend system life.

When is it time to replace my furnace?

If your furnace is more than 10–15 years old, requires frequent repairs, is noisy, has rising energy bills, or provides uneven heating, it’s probably time for replacement. Let our certified technicians evaluate how a newer, more efficient unit can save on costs and improve comfort.

Air Conditioning Services

Why isn't my AC cooling properly or why is airflow low?

Poor cooling or airflow can result from dirty filters, low refrigerant, blower issues, or equipment malfunctions. We offer comprehensive AC repair—including filter changes, refrigerant charging, coil cleaning, and blower motor service—to quickly restore proper cooling.

Is it better to repair or replace an aging AC unit?

If your AC is over 10 years old, it may be more economical to replace it—especially when repair costs approach replacement cost or it loses energy efficiency. We offer free estimates and can help determine the right decision for your home’s comfort and budget.
