FAQs
What does your 100 % Satisfaction Guarantee cover for heat repair?
If we service or repair your furnace or heat-pump and you are not completely satisfied with our workmanship, parts, or overall service within the first 12 months, we will return to make it right at no extra cost. If we still can’t meet your expectations, we will refund the portion of the invoice related to the unsatisfactory work. The guarantee applies to labor, replacement parts we supply, and the cleanliness of your home when we leave.
How quickly can you respond to a no-heat emergency in Belvidere?
Our technicians are on call 24/7, including weekends and holidays. For homes inside Belvidere city limits we aim to arrive at your door within 2 hours of your call; surrounding rural areas are typically reached within 3 hours. You’ll receive real-time text updates with the technician’s estimated arrival and a photo ID for your security.
Are your technicians certified to work on all furnace and heat-pump brands?
Yes. Every technician on our team is EPA-certified and factory-trained to service major brands such as Trane, Carrier, Lennox, Rheem, Goodman, and Mitsubishi. We also attend ongoing manufacturer update classes, so we are equipped to diagnose and repair older models as well as the latest high-efficiency equipment.
What steps do you take to diagnose and fix heating problems?
1) Visual inspection of the furnace/heat pump, thermostat, filters, and electrical connections. 2) Digital testing of voltage, amperage, gas pressure, and refrigerant levels (for heat pumps). 3) Combustion analysis to ensure safe CO levels. 4) Clear explanation of the problem and repair options with upfront pricing. 5) Completion of the approved repair, followed by system recalibration and safety checks. 6) Final test cycle to confirm reliable operation before we leave.
Will I get a written estimate and transparent pricing before work begins?
Absolutely. After the diagnosis is complete, we provide a written proposal that lists each recommended repair, parts and labor charges, any discounts, and applicable taxes. You approve the repair and price before tools come out of the truck. There are no hidden fees, ever. We also honor manufacturer warranties and file any warranty claims on your behalf.
What maintenance tips will help keep my heating system efficient after the repair?
• Change or clean air filters every 1–3 months. • Keep return and supply vents clear of furniture or rugs. • Schedule a professional tune-up every fall to inspect burners, heat exchangers, safety controls, and airflow. • For heat pumps, maintain at least 18 inches of clearance around the outdoor unit and rinse coils with a garden hose each spring and fall. • Install a programmable or smart thermostat to avoid unnecessary run-time. • Listen for unusual noises and call us at the first sign of trouble to prevent small issues from becoming costly repairs.
