FAQs
What qualifies as an HVAC emergency and when should I call for 24/7 service?
An HVAC emergency is any situation in which your heating or cooling system fails and poses a risk to your safety, health, or property. Examples include complete loss of heat in freezing weather, AC failure during extreme heat, burning smells, smoking or sparking equipment, refrigerant or gas leaks, and flooding from a clogged condensate line. If you experience any of these issues—or are unsure whether a problem is dangerous—call our 24/7 hotline immediately. A trained dispatcher will help you determine whether you need an urgent on-site response or can schedule a next-day visit.
How quickly can your technicians reach my home in Belvidere during an emergency?
Because we maintain fully staffed on-call crews and strategically station service vehicles throughout Boone County, our average arrival time within Belvidere city limits is 60–90 minutes. For rural addresses, we target a two-hour window or less, weather and traffic permitting. GPS-equipped vans allow our dispatcher to locate and route the closest available technician, ensuring the fastest possible response. You’ll receive text or phone updates with an estimated time of arrival so you’re never left guessing.
What brands and types of HVAC units do you carry for replacement?
We stock a broad inventory of furnaces, air conditioners, heat pumps, and ductless mini-splits from trusted manufacturers such as Trane, Carrier, Lennox, Rheem, and Mitsubishi Electric. Our warehouse in Belvidere keeps the most common residential sizes (1.5–5 tons for AC/heat pumps and 40,000–120,000 BTU furnaces) ready for immediate installation. We also have rapid-ship agreements with suppliers for specialty equipment, allowing most replacements to occur within 24 hours even if a unit isn’t in stock.
Can you replace my HVAC unit the same day as the emergency call?
In many cases, yes. If the diagnostic confirms that replacement is the best option—and the correct-sized unit is in our local inventory—we can begin removal of the old system and installation of the new one the same day. Typical furnace or air-conditioner change-outs take 6–10 hours, including start-up testing and code-required inspections. If unique duct modifications or electrical upgrades are needed, installation may extend into the next day, but we will provide temporary heating or cooling solutions to keep your home comfortable overnight.
How much will an emergency HVAC replacement cost, and do you offer financing?
Pricing depends on equipment size, efficiency rating (SEER2/AFUE), installation complexity, and whether ancillary components—such as thermostats, dampers, or line sets—need upgrading. A basic 2-ton 14.3-SEER2 AC replacement averages $4,500–$6,000, while a high-efficiency 96% AFUE furnace runs $4,000–$5,500 installed. Emergency service charges are waived when you proceed with a full system replacement. We partner with several lenders to offer same-day approval on 0% APR plans for 12–18 months or low-interest terms up to 120 months, so you can restore comfort without an upfront burden.
What steps can I take to minimize downtime while waiting for your technicians?
1. Turn off the HVAC system at the thermostat and breaker to prevent further damage. 2. For heating emergencies, close doors to unused rooms and use safe space heaters or fireplaces if available. 3. For cooling emergencies, draw curtains, use fans, and avoid heat-generating appliances. 4. Keep pets and children away from the equipment area. 5. Gather any warranty documents or previous service records to expedite diagnosis. 6. Clear a path to the indoor and outdoor units so technicians can work quickly upon arrival. Following these steps helps us restore your comfort faster and more safely.
