The HVAC Maintenance Scheduling Crisis: San Mateo County Homeowners Are Scrambling for 6-Month Advance Bookings in 2025
San Mateo County homeowners are facing an unprecedented challenge in 2025: securing HVAC maintenance appointments now requires booking up to six months in advance. This scheduling crisis stems from multiple converging factors that have fundamentally disrupted the traditional heating and cooling service industry, leaving homeowners struggling to maintain their systems and potentially facing costly emergency repairs.
The Perfect Storm Behind the Scheduling Crisis
Federal climate policy challenges HVAC contractors across Northern California as refrigerant shortages delay essential air conditioning services. The primary driver of this crisis is the EPA’s new refrigerant regulations that took effect January 1, 2025. The regulation prohibits the manufacture of air-conditioning or heat pump systems using refrigerants with a global warming potential (GWP) higher than 700.
The new government-approved refrigerant, known as R-454B, is in short supply—and air conditioning systems can’t run without it. “Unfortunately, they don’t have it, but when they have it, the price is super high on it,” he said. This shortage has created a domino effect throughout the industry, forcing contractors to prioritize emergency repairs over routine maintenance.
HVAC technicians have their hands full helping national retailers and other clients with largescale operations to systematically replace older units with new systems conforming to the new standard. These forward-thinking chains are among those first in line for the new 700 GWP-cooled systems as they roll out from manufacturers, so companies that expect to buy new systems in 2025 should plan for several months of lead time.
Why Maintenance Matters More Than Ever
The scheduling crisis makes regular maintenance more critical than ever before. Busy HVAC technicians frequently respond to calls of air conditioners not starting during the first hot day of the year, meaning you may have to wait a few days to get an HVAC contractor out to your home. Without proper maintenance, homeowners risk system failures during peak demand periods when emergency service calls are at their highest.
If you wait until summer to find out your compressor is broken, you may spend weeks waiting for a replacement part in the sweltering heat. Scheduling a spring AC tune-up allows more time to order and ship replacement parts. This proactive approach has become essential in the current environment where parts availability is unpredictable.
The San Mateo County Challenge
San Mateo County faces unique challenges that compound the national scheduling crisis. The region’s Mediterranean climate means HVAC systems work year-round, increasing wear and maintenance needs. South San Francisco has unique microclimates that affect how air conditioning systems perform. The marine influence means your system deals with both heat and humidity in ways that are different from inland areas, and the fog can create moisture issues that other regions don’t face.
Additionally, many homes in the county were built before modern HVAC systems became standard, requiring specialized knowledge and more frequent maintenance. Many homes in South San Francisco were built before air conditioning was common, so we frequently work with retrofitted systems that require special knowledge to repair properly.

Strategic Planning for Homeowners
Industry experts recommend that homeowners take immediate action to secure maintenance appointments. Air conditioner maintenance should ideally be performed annually, preferably in March or April before you turn the system on for the first time. A March or April AC tune-up allows plenty of time to identify and correct issues while outdoor temperatures are still comfortable. Additionally, this is a slow time for many HVAC technicians, so they often offer special pricing on maintenance in the spring.
Despite the challenges, all three contractors had the same advice for customers: be patient, do your homework and maintain your current system if it’s still working. This advice has become more relevant than ever as homeowners navigate the current crisis.
The Financial Impact
The scheduling crisis is driving up maintenance costs while simultaneously making emergency repairs more expensive. The average cost of AC maintenance ranges from $75 to $200. The factors that affect the price include the size and type of air conditioner, the region in which you live, and any additional services provided. However, the alternative—emergency repairs during peak season—can be significantly more costly.
Studies show regular maintenance can decrease HVAC energy costs by as much as 40%. If your AC unit is clogged with dust and debris, it’s going to have to work harder to cool your home, resulting in a higher monthly energy bill.
Looking Ahead
The HVAC maintenance scheduling crisis of 2025 represents a fundamental shift in how homeowners must approach system care. The increasing frequency and severity of hurricanes, wildfires and other natural disasters can create surging demand for replacement systems, parts and the service providers needed to install them. Coupled with manufacturing wait times, natural disasters pose yet another potential source of delay that can leave an unprepared restaurant or retailer waiting for weeks to restore lost HVAC service.
For San Mateo County homeowners, the message is clear: proactive planning and early scheduling are no longer optional—they’re essential for maintaining home comfort and avoiding costly emergency situations. Those who adapt to this new reality by booking maintenance appointments well in advance will be best positioned to weather the ongoing industry challenges.
