What Phoenix Residents Frequently Ask About Heating and Cooling
- Replace a gas furnace with another gas furnace, or switch to a heat pump?
- Stay with gas if your winter design temp is below 0°F and you have cheap natural gas — heat pumps still derate in extreme cold. Switch to a heat pump if winters are mild AND electricity isn't 2× the national rate AND a state rebate stacks. Run 10-year operating costs, not just install price.
- What AFUE rating should I look for in a new gas furnace?
- 95–98% AFUE for cold climates (condensing furnace; requires PVC venting and a condensate drain). 80% AFUE is acceptable in mild climates where the high-efficiency install premium doesn't pay back. Skip the 92–94% band — the price-to-efficiency curve is bad there.
- How do I find a specialist for high-efficiency cooling systems in Phoenix?
- Look for providers who hold manufacturer-dealer designations and maintain NATE-certified technicians on their staff. These certifications indicate that the company has verified expertise in installing and servicing high-efficiency equipment, which is essential for managing the thermal load in neighborhoods like Arcadia or Desert Ridge. Reviewing customer feedback for mentions of specific system upgrades can also help you identify contractors who specialize in modern, energy-efficient cooling solutions.
