Frequently Asked Questions
How long does a new heating and air conditioning installation take?
A standard residential heating and air conditioning installation typically takes one full day to complete, usually between 6 to 8 hours. Complete system installations that involve custom ductwork fabrication or full layout redesigns may require additional time.
Why is proper system load calculation important before installation?
Proper load calculation ensures your new system is accurately sized for your home's unique thermal needs. Oversized or undersized units lead to frequent short-cycling, high energy bills, humidity issues, and premature equipment failure.
What brands do you recommend for new HVAC installations?
As an authorized Lennox dealer, we install top-rated Lennox furnaces, heat pumps, and air conditioning units known for industry-leading efficiency and reliability. We also install other trusted equipment lines depending on your project requirements.
Do new HVAC installations include warranty coverage?
Yes, all new equipment installations include comprehensive manufacturer warranties covering functional parts for up to 10 years. Additionally, Furnace King provides a complete installation labor guarantee to ensure lasting peace of mind.
Can I finance my new heating and air conditioning installation?
Yes, we partner with WhyStack to provide flexible financing solutions that allow you to pay for your new installation through convenient monthly payments. This helps you install high-efficiency equipment without significant upfront cost.
