If a bedroom stays warm or a family room feels cold, bring that concern into the service conversation. Ask what the existing system is doing and which findings would support a repair, an airflow correction, or a different equipment choice.
Describe the rooms and the timing.
Tell us where comfort falls short, whether it happens in heating or cooling, and when you notice it. Mention if the problem is new, seasonal, or something the home has always had.
Share changes to the home.
Let us know about an addition, finished space, window or insulation work, or changes in how rooms are used. Have available plans and equipment information ready so those changes can be included in the discussion.
Ask how the recommendation was reached.
When replacement is proposed, ask how the home’s needs were assessed, how the existing ductwork was evaluated, and what the new equipment is expected to address. Review the explanation and complete scope before approving a capacity change.
Bigger is not automatically a better fit. ENERGY STAR advises sizing equipment from the home’s actual characteristics and warns that oversized equipment can cycle too often. It also identifies airflow and duct evaluation as installation considerations. [3] Ask how those factors apply to your home.
Match the local requirements to the actual work.
Homer Glen’s Building Department states that permits are no longer needed for HVAC system replacements, a change effective May 1, 2025. [1] Confirm that your proposed work falls within that replacement category and that the property is under the Village’s jurisdiction.
The Village’s permit guidance separately lists additions and interior or exterior remodeling among projects that typically require permits. [2] If HVAC work is part of a larger project, describe the full scope to Building Department staff and confirm the applicable requirements before work begins.
The Building Department also states that contractors must register. [1] Confirm the applicable contractor requirements and any approvals or inspections for related work as part of the project arrangements.

ENERGY STAR recommends professional preseason checkups, with cooling checked in spring and heating in fall. [4] Routine care is also a useful time to discuss changes in how your home feels.
Explain any comfort changes.
Share the affected rooms, when the concern occurs, and any recent work on the home or system. Mention active problems when booking so we can discuss diagnosis beyond routine maintenance.

Answers before you arrange service.
Is Generations HVAC based in Homer Glen?
Our home base is Lombard, and we serve Homer Glen. Share your address and the help you need so we can confirm service arrangements, availability, and applicable charges.
Will a bigger air conditioner fix a room that stays warm?
It needs an assessment first. ENERGY STAR cautions that oversized equipment can cycle too frequently and advises evaluating system airflow and ducts. [3] Tell us which rooms are affected so the proposed solution can address the findings.
Should replacement equipment have the same capacity as the old system?
The existing equipment is useful background, but ask how the proposed capacity was determined for your home. Share comfort concerns and known changes to the house, and review the assessment before choosing replacement equipment.
Does Homer Glen require a permit for an HVAC replacement?
The Village’s Building Department states that HVAC system replacements no longer require permits, effective May 1, 2025. [1] Confirm that your address and complete project scope qualify; new installations or related work need their own requirements checked.
What if HVAC work is part of an addition or remodel?
Share the full project with the Building Department. Homer Glen’s permit guidance lists additions and remodeling as typical permit projects. [2] Coordinate the HVAC scope with the larger project and confirm any required reviews and inspections.
Can I discuss an uncomfortable room during a maintenance visit?
Yes. Mention it when arranging service and describe when it occurs. We’ll discuss whether the concern can be addressed within the maintenance scope or needs a separate diagnostic assessment, including applicable charges.
