Keeping Homes & Workplaces Cool
Air conditioning supports comfortable, steady indoor conditions across changing temperatures, helping homes and businesses manage heat throughout the day. At Gilmour Air & Electrical, we install systems planned around airflow, room size and how each space is used, ensuring cooling feels even and consistent. We position units to deliver balanced coverage, avoid hot spots and respond efficiently to variations in outdoor conditions.
Our servicing keeps filters, coils and components in good condition so systems maintain reliable performance over time. When older units begin to lose efficiency or struggle with heavier demand, we offer upgrades and replacements that improve cooling quality and energy use.

Residential Air Conditioning
Residential air conditioning needs to support households with varying temperatures and room layouts, delivering comfort where it’s needed most. We assess how heat moves through the home, identifying areas that warm quickly, rooms that require quieter operation and spaces that benefit from stronger airflow. Window placement, ceiling height and insulation levels all influence the type and size of system needed.
Daily habits also shape cooling requirements—such as when the home is occupied, which rooms are lived in the most and how quickly indoor heat builds. By aligning system design with these patterns, we help ensure cooling stays steady without excessive energy use. This creates a balanced, efficient setup tailored to household routines.
Commercial Air Conditioning
Commercial air conditioning can be tailored to varying business environments, from staff work areas to customer spaces and equipment-heavy zones. We consider occupancy changes, extended operating hours and heat output from lighting or machinery when planning system layout and capacity. Zoning is often essential in commercial settings, allowing different areas to hold different temperatures without affecting overall performance.
Consistent airflow is also important, especially in spaces with high traffic or frequent opening of external doors. We design systems that handle these fluctuations while maintaining cooling efficiency. Long-term service access and expandability are built into every installation so businesses can scale operations without compromising performance or comfort.
Frequently Asked Questions
What causes my AC to make a whistling sound when it runs?
Whistling often comes from restricted airflow at vents or around filters. It may also indicate ductwork leaks drawing air through small gaps. These issues reduce system efficiency and cooling accuracy. Restoring proper airflow usually eliminates the noise.
Why is my air conditioner short-cycling on and off frequently?
Short cycling may signal thermostat placement issues, a refrigerant imbalance or an oversized system. It prevents the unit from running efficiently and can increase wear. Over time, this can lead to higher energy use and reduced cooling consistency. A diagnostic check identifies the exact cause.
How can I improve cooling in rooms that get afternoon sun?
Improving insulation and shading helps reduce heat gain. Adjusting airflow settings or relocating return air paths may also improve comfort. In some layouts, zoning or a secondary unit may be recommended. We can evaluate the space and suggest the most practical solution.
