Quotes are free, itemized, and good for 30 days." } }, { "@type": "Question", "name": "When is replacement smarter than another repair?", "acceptedAnswer": { "@type": "Answer", "text": "Three rules of thumb: the unit is 15+ years old, the repair costs more than half the price of new, or the heat exchanger is cracked. Hit any one of those and the math almost always favours replacement — especially with current high-efficiency rebates." } }, { "@type": "Question", "name": "How long does a furnace install take?", "acceptedAnswer": { "@type": "Answer", "text": "Most straight swaps are done in a single day, usually 6–8 hours from old unit out to new unit commissioned.

Going to 98% modulating makes sense in larger homes (2,500+ sq ft) or homes that run heat 8+ months a year." } }, { "@type": "Question", "name": "Do you offer financing for a new furnace?", "acceptedAnswer": { "@type": "Answer", "text": "Yes. We offer 0% financing for up to 60 months on approved credit, plus monthly plans starting around $49/month. Combined with utility rebates, most homeowners replace without paying anything upfront." } }, { "@type": "Question", "name": "What brands do you install?", "acceptedAnswer": { "@type": "Answer", "text": "Lennox, Carrier, Trane, Goodman, Rheem, and Bryant.

Ivan and his crew did a fantastic job moving our A/C unit and installing a heating system in our garage. They were completely on time, on budget, and very reasonably priced. What really stood out was the great respect they showed for our home and yard. They used drop cloths inside and tarps outside, taking extra care to minimize the mess and clean up after themselves completely. We’ve used other Plumbing & HVAC contractors in the past who were just okay, but Air Force's service quality was a level above all of them. Highly recommend!

The technicians were professional, knowledgeable, and completed the installation efficiently.

They came the next day at the agreed upon time. 2) The quote was reasonable and about $50 less than others (tight market). 3) The installation was scheduled quickly, and done well the following week. 4) It appears as if the work was done professionally with an attention to detail. It's still too cold to see how everything works, but will update the review as needed. 4) Communication was prompt and helpful. I would recommend Ivan and Air Force Heating in the future.
