Common questions

Is it worth replacing 20 year old windows for AC efficiency?

Absolutely. Older windows in Colorado often lack the insulation needed to keep cool air in and warm air out, making your AC work harder. Upgrading can significantly improve energy efficiency and comfort, especially during those warmer Denver days.

What is the average cost of installing a window AC unit?

The overall cost depends on factors like the window type, the size and weight of the AC unit, and any specific structural requirements. Additional support or sealing materials might be needed. We provide a free phone quote to give you a clear picture.

What is the correct way to install a window AC unit?

A proper installation involves securing the unit firmly to prevent vibration and ensuring a watertight seal around the edges. We make sure the unit is slightly tilted outward to allow condensation to drain away. This is crucial for maintaining performance in Colorado's varied weather.

How much does Home Depot charge to install a window AC unit?

Installation fees can differ based on the service provider and the specifics of the job. It's always a good idea to get multiple estimates. We offer a straightforward process to assess your needs and provide an accurate quote.

Is it cheaper to install windows yourself?

While you might save on labor initially, improper DIY installation can lead to inefficient cooling, energy waste, or even damage. For a secure and effective setup that stands up to Colorado's climate, professional installation is recommended.

How do I prepare my window for AC installation in Colorado?

Make sure your window opens and closes easily and is free from obstructions. We'll inspect the frame for stability and any necessary modifications. A well-prepared window ensures a secure and efficient installation for your Denver home.
