OUR SERVICES
Naturally, O’Callaghan provides service and repairs to home and commercial heating and cooling systems. However, we also offer a number of other services, making us Atlanta’s full-service HVAC provider.
• Air Quality – We can supply and install air purifiers, humidifiers, and dehumidifiers in your home or office, and we are also certified air duct cleaners.
• New Installations – We can design and install any heating, cooling, and/or air quality system in your home or light commercial site. Whether you are looking for affordability, energy efficiency, quiet operation, or a combination of all three, we can design a solution that will fit both your building and your budget.
• System Replacements – A new HVAC system can provide up to 30% energy savings, not to mention greater reliability and easier maintenance than outdated systems.
