The HVAC market in London, Ohio, is driven by a humid continental climate with hot, humid summers (average high of 85°F) and cold winters (average low of 20°F). This creates a consistent, year-round demand for both robust heating (furnaces, heat pumps) and effective air conditioning. Local providers must be adept at servicing a wide range of systems to handle the significant temperature swings. The market is competitive with several long-standing local providers who emphasize reliability, 24/7 emergency service for extreme temperature events, and expertise in improving home energy efficiency to combat both summer humidity and winter heat loss.

Get answers to common questions about hvac services in London, Ohio.
For a full system replacement in London, homeowners can expect to pay between $5,000 and $12,000+, depending on the system's size (measured in tons/BTUs), efficiency rating (SEER for AC, AFUE for furnace), and complexity of installation. Ohio's wide temperature swings mean properly sizing the unit for both summer heat and winter cold is critical, which impacts cost. Always get a detailed, written estimate that includes removal of the old unit, new refrigerant lines if needed, and all labor.
The ideal times are during the shoulder seasons—early spring (March-April) before cooling demand hits and early fall (September-October) before heating season. Scheduling during these periods ensures greater technician availability and often leads to promotional pricing. Waiting until the peak of a hot Madison County summer or a cold winter snap often results in emergency service fees and longer wait times due to high demand.
In Ohio, all HVAC contractors must be licensed by the Ohio Construction Industry Licensing Board (OCILB). For London homeowners, it's crucial to verify this license. Additionally, check for rebates from Columbia Gas of Ohio for high-efficiency furnace upgrades and from your electric provider for efficient air conditioners. The federal tax credits for qualified energy-efficient equipment also apply, providing significant savings.
Beyond verifying the required Ohio state license, look for established local companies with strong reputations in Madison County. They will be most familiar with local building codes and the specific needs of our older homes. Always ask for proof of liability insurance, check online reviews specific to central Ohio, and request references from recent installations. A trustworthy contractor will perform a detailed load calculation (Manual J) for your home, not just recommend a unit based on square footage alone.
This depends on the repair cost, efficiency, and reliability. For a repair costing over 50% of a replacement's value, replacement is often wiser. Given Ohio's humid summers, older, inefficient AC units (below 13 SEER) struggle and drive up energy bills significantly. Modern, high-efficiency systems (16+ SEER) offer much better dehumidification and comfort. If your furnace is over 15 years old and your AC is over 10, a proactive replacement can prevent a costly mid-winter or mid-summer failure.
