Your Local HVAC & Refrigeration Company in Hayward
At Cool Aid, we pride ourselves on being a locally-focused HVAC and refrigeration company serving Hayward, from Downtown Hayward to South Hayward, Castro Valley, and Hayward Hills. Our technicians understand the specific cooling and heating demands of the Bay Area and have handled countless residential and commercial systems in every type of building, from single-family homes to large commercial complexes.
For example, in Downtown Hayward, we recently completed a commercial AC installation for a multi-story office building along Mission Boulevard, reducing energy costs by 20% for the client. Meanwhile, in South Hayward, our team helped a local family replace their aging furnace and install a ductless heat pump system that provides consistent warmth during the winter months.

Residential HVAC Solutions in Hayward
We offer comprehensive residential HVAC services designed to keep Hayward homeowners comfortable while maximizing energy efficiency. Our team provides repair, replacement, installation, and maintenance, all with a focus on long-term reliability and reduced utility costs.
Many Hayward residents rely on us for preventative maintenance programs that keep their systems running efficiently year-round. For example, one homeowner in Hayward Hills opted for our annual inspection program and avoided a costly AC breakdown during a heatwave in August, saving them hundreds in emergency repairs.
Air Conditioning Repair, Replacement & Installation for Hayward Homes
Nothing is more frustrating than an AC that fails when you need it most. Common problems we see in Hayward homes include:
- AC blowing warm air
- Low or uneven airflow
- Frequent cycling or system shutdowns
- Outdated, inefficient units
Cool Aid provides energy-efficient solutions that are tailored for Hayward’s mild yet occasionally hot climate. We also install smart thermostats to help homeowners reduce energy bills and maintain consistent comfort.
For instance, a family in South Hayward had a 15-year-old central AC system that was struggling to cool their 2,500 sq ft home. Our team replaced it with a modern energy-efficient unit paired with a smart thermostat, resulting in improved airflow, lower energy bills, and a noticeably cooler home even during the peak of summer.
Heating System Installation & Preventive Maintenance
Hayward may not have the harshest winters, but reliable heating is still essential. We install and maintain:
- Furnaces
- Heat pumps
- Ductless heating systems
Regular preventive maintenance ensures that your heating system runs efficiently and avoids costly breakdowns during unexpected cold snaps. A recent project in Castro Valley involved upgrading a home’s old furnace and implementing a seasonal maintenance plan. The family reported improved comfort and quieter operation after the installation.
Indoor Air Quality & Humidity Control Solutions
Proper indoor air quality is essential for a healthy home environment. Cool Aid offers:
- Air purifiers
- Humidifiers and dehumidifiers
- Advanced filtration systems
Our solutions reduce allergens, control humidity, and improve overall indoor comfort. One client in Hayward Hills noticed a significant decrease in dust and allergy symptoms after installing a high-efficiency air purifier paired with a duct humidifier.
Hayward is home to a wide range of commercial properties—from restaurants and retail spaces to offices and industrial facilities. Cool Aid provides tailored HVAC and refrigeration solutions to ensure these businesses run smoothly, reduce downtime, and maintain a comfortable environment for employees and customers alike.
We recently completed a project at a local restaurant in Downtown Hayward, installing a new walk-in cooler and replacing an outdated rooftop AC unit. The upgrades increased energy efficiency, prevented frequent service interruptions, and ensured the kitchen staff could work comfortably even during peak summer months.
Commercial AC Installation & Rooftop Unit Services
Large commercial properties demand high-capacity HVAC systems. Our technicians specialize in:
- Installing energy-efficient commercial AC systems
- Routine preventive maintenance to reduce costly breakdowns

Server Room Cooling & Critical System Solutions
Precision cooling is critical for tech offices, data centers, and mission-critical systems. Our services include:
- Installation of energy-efficient server room AC units
