FAQ
Frequently Asked Questions
Answers to the most common questions we hear from homeowners.
In Illinois, HVAC contractors must hold a state mechanical contractor's license. Verify any contractor's license status through the Illinois contractor licensing board website before allowing work. HVAC Master Pros employs only state-licensed technicians and carries full general liability and workers' compensation insurance throughout Illinois.
In Illinois, the most frequent HVAC calls involve capacitor failures (especially after high-demand summer periods), refrigerant leaks from aging copper coils, clogged condensate drain lines that cause water damage, dirty condenser coils from dust and cottonwood seeds, and furnace ignitor failures heading into winter. Routine annual maintenance prevents the majority of these issues.
A standard central AC replacement in Illinois — air handler and outdoor condenser — takes 4–8 hours for a two-person crew. Installations requiring new refrigerant lines, new electrical service, or significant ductwork modifications may take 1–2 full days. Permitting timelines in different Illinois jurisdictions can vary; we handle all permits as part of our installation service.
AC repair costs across Illinois average between $175–$650. Common repairs include capacitor replacements ($150–$275), refrigerant recharges ($250–$450), blower motor replacements ($300–$600), and contactor repairs ($150–$300). HVAC Master Pros provides upfront flat-rate pricing with no hidden fees anywhere in Illinois.
In most of Illinois's climate, we recommend an AC tune-up each spring and a heating system tune-up each fall. Areas of Illinois with high humidity or heavy pollen may benefit from twice-yearly evaporator coil cleanings to prevent mold buildup and maintain airflow.
