We prioritize emergency service calls for heating and cooling failures, especially during extreme weather. We typically respond within a few hours for emergency situations in the Frankfort area. Call us at (708) 231-4800 any time you need emergency HVAC service.
Yes, we service all major HVAC brands including Rheem, Armstrong, Carrier, Trane, Lennox, York, Mitsubishi, and others. Our technicians have experience with the most common residential and commercial HVAC equipment and can service your system regardless of brand or who installed it.
We recommend annual professional maintenance for most HVAC systems—typically spring service for air conditioning and fall service for heating equipment. Systems that provide both heating and cooling (like heat pumps) benefit from twice-yearly service. Regular maintenance prevents most unexpected failures and maintains efficiency.
Proper sizing requires calculating your home's specific heating and cooling loads based on square footage, insulation, windows, orientation, and other factors. Oversized systems cycle frequently and don't control humidity well. Undersized systems run constantly and never quite reach comfortable temperatures. We perform proper load calculations to determine the right size equipment for your home.
High-efficiency systems cost more upfront but provide lower operating costs throughout their life. In a climate like Frankfort's with both hot summers and cold winters, the energy savings can be substantial. We help you evaluate the payback period based on your usage and energy costs to make an informed decision about efficiency levels.
Yes, we offer comprehensive maintenance plans for residential and commercial customers in Frankfort. Maintenance plans include scheduled service, priority emergency response, and discounts on repairs. Plans ensure your system receives the regular attention needed for reliable operation and long life.
Absolutely. We provide complete indoor air quality solutions including high-efficiency filtration, HEPA systems, UV lights, air purifiers, humidifiers, and dehumidifiers. We assess your specific concerns (allergies, asthma, odors, humidity) and recommend appropriate solutions for your home.
With proper maintenance, air conditioners and furnaces typically last 15-20 years, heat pumps last 15-18 years, and boilers often last 20-25 years. Actual lifespan varies based on maintenance quality, usage, and installation quality. Regular professional maintenance extends equipment life significantly.
Yes, we serve Frankfort businesses with comprehensive commercial HVAC services including rooftop units, commercial refrigeration, cooking equipment, and preventive maintenance programs. We understand the critical nature of commercial HVAC and provide responsive service to minimize business disruption.
First, check that your thermostat is set to cooling mode and the temperature setting is below current room temperature. Check your circuit breaker to ensure power to the outdoor unit. Replace or clean your air filter. If these steps don't resolve the problem, call us for professional diagnosis and repair. Don't run the system continuously if it's not cooling—this can cause additional damage.
Emergency service calls during off-hours (evenings, weekends, holidays) may include additional fees for rapid response. However, we believe in fair, transparent pricing and will always provide cost information before beginning work. The peace of mind and rapid comfort restoration often justify emergency service costs when your heating or cooling has failed.
