The answer to 'how much does maintenance cost' is that the cost of HVAC maintenance can vary significantly depending on a number of factors. In general, routine maintenance for a typical residential HVAC system can range from $75 to $300 per visit, with most homeowners spending around $150 to $200 for a bi-annual tune-up.
The actual cost will depend on the size and complexity of your HVAC system, your location, the specific services included, and whether you have an ongoing service contract. Older or more complex systems may require more extensive maintenance, which can increase the cost. Additionally, the time of year can affect pricing, as demand for HVAC services is often higher during the peak heating and cooling seasons.
