Frequently Asked HVAC Questions
When should I repair my HVAC system instead of replacing it?
A helpful guideline is the $5,000 Rule. If the age of your HVAC system multiplied by the estimated repair cost exceeds $5,000, replacement is often the more cost-effective option. A repair can still make sense when the equipment is otherwise reliable, and the issue is limited to a single component. We can inspect your system and walk you through both options so you can make an informed decision.
How often should I schedule HVAC maintenance?
Heating and cooling systems generally benefit from service before their major operating season. Woodstock Heating & Cooling’s furnace and AC maintenance agreements include a heating-season clean and check and a cooling-season clean and check to keep both sides of the system on a regular service schedule.
Can you service homes with older ductwork?
Yes. Many homes in McHenry County and Northern Illinois, like older farmhouses and mid-century builds, still rely on aging ductwork. We can service these systems and evaluate how well your existing ductwork is performing in our local climate. Our technicians can inspect for leaks, poor insulation, airflow restrictions, and sizing issues, then recommend the right service to help improve comfort and energy efficiency.
