Frequently asked: Ohio hvac technicians
Are HVAC contractors state-licensed in Ohio?
Yes. HVAC contractors must hold an Ohio Construction Industry Licensing Board (OCILB) license. ProFix shows license numbers on profiles where the contractor publishes them, and links to the Ohio eLicense Center so you can confirm active status. EPA Section 608 refrigerant cards are required separately for refrigerant work.
What is a Manual J load calculation and why does it matter?
Manual J is the industry-standard residential load calculation. A contractor who ‘rule of thumb' sizes by square footage will often oversize the system, which short-cycles, dehumidifies poorly, and shortens equipment life. Ask for the Manual J output and the AHRI-matched equipment number on any replacement quote.
How much does a furnace or AC replacement cost in Ohio?
Furnace replacement runs roughly $4,000-$8,000 installed for a standard 90-95% AFUE gas unit. Central AC runs $4,500-$11,000 depending on tonnage, SEER rating, and ductwork condition. The federal Energy Efficient Home Improvement Credit (section 25C) that used to offset heat-pump conversions ended under the One Big Beautiful Bill Act (Pub. L. 119-21) for property placed in service after December 31, 2025, so check current Ohio utility and state energy programs instead. ProFix cost guides show typical NW Ohio ranges by job type.
When should I tune up my furnace?
Schedule annually in September or early October before the heating season. A standard tune-up runs $89-$129 and typically pays for itself in fuel savings and by catching cracked heat exchangers, fouled burners, or weak flame sensors before they become emergency calls in January.
Should I get a heat pump instead of a furnace?
Heat pumps work in Ohio's climate, especially cold-climate models rated for 100% capacity at 5°F or lower. They cost $1,500-$3,500 more upfront than a standard furnace but heat AND cool. The federal Energy Efficient Home Improvement Credit (section 25C) that used to help with this ended under the One Big Beautiful Bill Act (Pub. L. 119-21) for property placed in service after December 31, 2025, so check current Ohio utility and state energy programs instead. Ask your HVAC contractor to model both options against your local gas vs electric rates.
