Frequently Asked Questions

Sunset Heating and Air Conditioning offers 24/7 emergency HVAC service throughout Country Club Hills, Homewood, Matteson, Tinley Park, and the surrounding south suburbs. In most cases we can have a certified technician at your door the same day you call — often within a few hours. We understand that a broken furnace in a Chicago winter or a failed AC in a summer heat wave cannot wait, so emergency calls always move to the front of the line.

Our technicians are trained and certified to work on all major brands, including Carrier, Lennox, Trane, Goodman, Rheem, Bryant, Amana, and more. Whether your system was installed years ago by another company or purchased brand-new, we can diagnose, repair, and maintain it. We also offer replacement systems from leading manufacturers when a repair is no longer cost-effective.

Most HVAC manufacturers and energy experts recommend a professional tune-up once a year for each system — your furnace in the fall before heating season, and your air conditioner in the spring before cooling season. Regular maintenance extends equipment life, keeps your warranty valid, lowers energy bills, and catches small problems before they become expensive breakdowns. Sunset Heating and Air Conditioning offers affordable maintenance plans that make it easy to stay on schedule.

Common warning signs include: unusual noises such as banging, rattling, or squealing; uneven heating with some rooms much colder than others; a yellow or flickering burner flame instead of a steady blue one; a sudden spike in your gas or electric bill; frequent on-and-off cycling; the furnace is 15 or more years old; or you have had multiple repairs in a single season. If your system is showing any of these symptoms, call us for a free diagnostic — we will give you an honest assessment of whether repair or replacement makes more financial sense.

Yes. We provide free, no-obligation in-home estimates for all new heating and cooling system installations. One of our comfort advisors will assess your home's size, insulation, ductwork, and existing equipment, then recommend the right system and capacity for your specific needs. We will walk you through the options, explain the differences in efficiency ratings (SEER and AFUE), and provide a detailed written quote with no hidden fees.

Yes — significantly. Older furnaces and air conditioners often run at 60–80% efficiency, while today's high-efficiency systems can reach 96–98% AFUE for furnaces and 20+ SEER for air conditioners. Homeowners in the Chicago south suburbs who upgrade from an aging system frequently see 20–40% reductions in their monthly heating and cooling costs. Over the life of the equipment, those savings can more than offset the cost of a new system, especially with rising energy prices.

First, check that your thermostat is set to heat and the temperature is above the current room temperature. Make sure the furnace switch (usually on the wall near the unit) is in the on position and check your circuit breaker for any tripped breakers. Change your air filter if it looks clogged, as a dirty filter can cause a furnace to shut down. In the meantime, use electric space heaters safely, keep interior doors closed to retain warmth, and layer up with blankets. If you smell gas, leave the home immediately and call your gas company. Our technicians are dispatched quickly and will call ahead with an estimated arrival time.
