HVAC Services in Ajax

Ajax homeowners trust Megacity HVAC for reliable heating and cooling service. Whether you need a furnace replacement in South Ajax, AC installation near the waterfront, or a heat pump upgrade in Pickering Village — our TSSA-certified technicians deliver professional HVAC solutions backed by 25+ years of GTA experience and a perfect customer rating. Ajax is a well-established Durham Region community with a mix of 1970s–80s homes in South Ajax and the waterfront area, alongside newer townhouse and detached home developments in North Ajax. Our technicians understand the specific HVAC challenges of Ajax homes, from replacing aging furnaces in original South Ajax builds to optimizing airflow in the multi-level townhouse designs common in newer communities.

Ajax's residential core was developed in the 1970s and 1980s, with South Ajax and the waterfront area featuring split-level homes, bungalows, and early two-storey designs with original HVAC systems that have reached or exceeded their expected lifespan. Many of these homes have single-stage 60–80% efficiency furnaces paired with older R-22 refrigerant AC units that can no longer be recharged cost-effectively. North Ajax developments from the 2000s–2010s have newer but often builder-minimum systems, and the stacked townhouse and condo developments along Bayly Street present unique ductwork and access challenges for service and replacement.
