Struggling with a hot room that just won't cool down? Whether it's an upstairs bedroom, garage office, or rental unit, installing a window air conditioning unit is one of the fastest and most affordable ways to beat the heat. At Homeowner Handy, we specialize in clean, energy-efficient window AC installations—no matter which direction your windows open.

Even though we enjoy generally mild temperatures in areas like Mountain View, Palo Alto, Cupertino, and Santa Clara, the occasional heat wave or stuffy upstairs room can make things uncomfortable. A properly installed window AC unit can help regulate the temperature and make your space feel much more comfortable year-round.

1. AC Installation for Vertical and Horizontal Windows Window AC units are traditionally designed for vertical-sliding windows, but we install them just as easily in horizontal or casement-style windows using smart, secure solutions. You don't need to replace your window or buy an expensive custom unit—we work with what you have.

2. Professional Plexiglass Seals for a Clean Look A sloppy installation can ruin the look of your room and allow hot air and bugs to seep through. That’s why we use high-quality, clear plexiglass to seal off any open space around the AC unit. It keeps your room cooler, looks professional, and helps with long-term energy efficiency.

3. Energy Efficiency That Saves You Money Our installations are designed with insulation in mind. We ensure that no hot air gets in and no cool air gets out. That means your AC runs less often and uses less electricity—saving you money all summer long.

4. Secure Mounting for Peace of Mind A poorly mounted AC unit can rattle, leak, or even fall out. We use brackets and support materials to keep your unit rock-solid and perfectly angled to drain properly.

5. Flexible Scheduling and Expert Service We know you're busy, so we offer flexible scheduling and fast, reliable service. Every installation is done with care, precision, and your satisfaction guaranteed.

Call to Action: Even in the mild Bay Area climate, having a window AC unit can make a big difference during the warmer months. Whether you live in Mountain View, Palo Alto, Cupertino, Santa Clara, or nearby, Homeowner Handy is your local expert for professional window AC installation. Call or text us today to schedule your install and enjoy a cooler, more comfortable home.
