Heating, Cooling & Home Comfort: Frequently Asked Questions

How much does AC repair cost in Mundelein?

Cost depends on the issue — a low refrigerant charge or a failed capacitor is a much smaller repair than a compressor replacement. With Mundelein summers regularly pushing into the 80s and 90s, Comfort Cavalry Heating & Air diagnoses the problem first and gives you upfront pricing before any work begins, so there are no surprises on the invoice.

Why does my furnace short-cycle or blow cold air during a Lake County cold snap?

A furnace that turns on and off too quickly is often caused by a dirty flame sensor, a clogged filter restricting airflow, or a cracked heat exchanger — the last of which is a safety issue and should be inspected right away, especially with how far temperatures can drop here in Illinois. Our technicians carry the Heat Exchanger Expert® certification and can diagnose the cause on the first visit.

How long does a water heater replacement take in an older Mundelein home?

Most standard tank water heater replacements are completed in a single visit. Many of the older homes near downtown Mundelein have galvanized or undersized supply lines, which can add time if they need updating — something we’ll flag during your estimate rather than after the fact.

Is a ductless mini-split a good fit for an older home near downtown Mundelein?

Ductless systems are a popular option for additions, garage conversions, and older homes near downtown Mundelein that don’t have existing ductwork, since they install with just a small wall or ceiling unit and a conduit run rather than tearing into walls.

Do you offer same-day or emergency HVAC service in Mundelein?

Yes. Comfort Cavalry Heating & Air offers same-day and emergency service for no-heat, no-cool, and water heater failures for Mundelein homeowners whenever possible, particularly during peak summer and winter demand.

Why does my house still feel humid even with the AC running in a home near Diamond Lake?

An oversized or short-cycling air conditioner cools the air quickly without running long enough to pull out humidity — a common issue in homes near Diamond Lake and Countryside where lake-effect moisture is higher. A properly sized system, or a whole-house dehumidifier, usually solves it.

How often should Mundelein homeowners schedule HVAC maintenance?

Given how much Illinois systems get used in both directions — cooling through humid summers and heating through long winters — most manufacturers recommend maintenance twice a year: once for the AC before summer and once for the furnace before the cold sets in. It also keeps manufacturer warranties valid.
