Regular maintenance and timely repairs are the secrets to a long-lasting, efficient HVAC system. At Ac by Day C, we offer comprehensive diagnostics, seasonal maintenance, and repair services for both residential and commercial equipment. Our technicians are trained to troubleshoot issues quickly and accurately — whether it’s a gas furnace that won’t ignite, an electric heat pump blowing cold air, or a hydronic system with uneven heating.

We begin every repair with a thorough diagnostic to identify the root cause. Our residential diagnostic fee is just $85 within a 30-mile radius, and we apply that fee toward the repair if you choose to move forward. Commercial diagnostics are $125, reflecting the additional complexity of larger systems. We keep our repair prices reasonable and economically friendly, because we believe staying comfortable shouldn’t break the bank.

Preventive maintenance is even better than repair. Our seasonal maintenance plans improve performance, boost efficiency, and reduce the likelihood of emergency breakdowns. We service all makes and models, and our honest recommendations mean we never push unnecessary work. For reliable HVAC care in Winston-Salem, trust the team that treats your home or business like our own.
