Q&A
What should I do if my pilot light keeps going out in my Wolfeboro home?
A pilot light that frequently goes out can indicate issues like a dirty thermocouple, drafts, or gas supply problems common in older Wolfeboro homes. Key Heating & Air Conditioning's technicians are trained to diagnose and repair these issues safely. They'll inspect your system, clean components, and ensure proper ventilation to restore reliable operation. For persistent problems, they may recommend maintenance or an upgrade to a more efficient system. Their 24/7 service means help is available whenever you need it.
How often should I schedule HVAC maintenance in the Wolfeboro area?
For Wolfeboro's climate with cold winters and humid summers, we recommend scheduling HVAC maintenance at least twice a year—ideally in spring for cooling systems and fall for heating. Key Heating & Air Conditioning offers Maintenance Memberships that include priority scheduling, thorough inspections, and cleaning of components like air filters to prevent clogs. This helps improve efficiency, extend system lifespan, and reduce the risk of breakdowns during extreme weather. Their factory-trained technicians can tailor a plan based on your specific system and usage.

They specialize in systems from York, Mitsubishi, Bryant, Carrier, Lennox, Bosch, Buderus, and Climate Master, among others. As certified Mitsubishi Diamond Elite Contractors, they have particular expertise in Mitsubishi Electric Cooling & Heating systems. Their team can help you choose the right brand for your Wolfeboro home, whether it's a high-SEER unit, geothermal system, or ductless setup, ensuring proper installation and ongoing support.
