Question 1

When should I replace my furnace in Chicago?

Accepted Answer

Furnaces typically last 18-20 years with regular maintenance. Consider replacement if repairs become frequent, energy bills keep increasing, your home heats unevenly, you hear strange noises from vents, or the furnace cycles on and off frequently. Given Chicago's brutal winters, don't wait until your furnace fails completely.

Question 2

Is a dual-fuel hybrid system worth it in Chicago?

Accepted Answer

Yes, dual-fuel systems are excellent for Chicago's climate. They combine a heat pump with a gas furnace. The heat pump handles heating efficiently in mild weather above 40 degrees Fahrenheit, and the furnace takes over in extreme cold. This can significantly reduce heating costs compared to furnace-only systems while providing year-round comfort.

Question 3

What HVAC rebates are available in Chicago?

Accepted Answer

Chicago homeowners can access multiple rebates through ComEd for air source heat pumps, standard efficiency heat pumps, geothermal systems, and smart thermostats. Peoples Gas provides rebates for high-efficiency furnaces and efficient boilers. Contact these utilities directly or ask your contractor about current programs and eligibility requirements.

Question 4

Do I need a permit for HVAC work in Chicago?

Accepted Answer

Yes, Chicago requires permits for most HVAC work including new installations, replacements, and major repairs. The Express Permit Program streamlines approvals for common residential work like equipment replacement. Permits must be filed by a licensed general contractor. Working without permits can result in fines and complications when selling your home.

Question 5

How often should I have my HVAC system inspected?

Accepted Answer

Have your HVAC system professionally inspected at least once a year, ideally before winter to ensure your furnace works properly. In Chicago's extreme climate, many homeowners opt for bi-annual maintenance: one check before summer for AC and one before winter for heating. Regular maintenance prevents emergency breakdowns and extends system life.

Question 6

What are signs my heat pump needs repair?

Accepted Answer

Warning signs include odd noises such as banging, whistling, or screeching, rising energy bills, burning or musty smells from vents, home not reaching set temperature, lack of airflow from vents, and the system turning on and off frequently. In Chicago's winters, address these issues immediately to avoid being without heat.

Question 7

Should I get a gas furnace or heat pump in Chicago?

Accepted Answer

For Chicago's climate, most experts recommend either a high-efficiency gas furnace with 95% or higher AFUE rating or a dual-fuel hybrid system. A standalone heat pump isn't sufficient for Chicago's extreme winters when temperatures below 40 degrees reduce heat pump efficiency. A dual-fuel system gives you the best of both: efficient heat pump operation in mild weather and reliable gas heat during cold snaps.

Question 8

How long does HVAC installation take in Chicago?

Accepted Answer

Standard HVAC replacement takes eight hours to one full day for experienced technicians. Complex installations in older Chicago homes with accessibility issues or need for ductwork modifications may extend to two or three days. Always choose licensed contractors who can handle Chicago's permitting requirements.

Question 9

What minimum efficiency ratings should I look for?

Accepted Answer

For Chicago installations, minimum requirements are SEER2 14 for AC and AFUE 80% for furnaces. However, for Chicago's climate and to qualify for rebates, aim higher: 95% or higher AFUE for furnaces, 15.2 or higher SEER2 for air conditioners, and 17 or higher SEER2 for heat pumps. Higher efficiency means lower bills during Chicago's long heating and cooling seasons.
