"I called and they sent someone out the next day. They were prompt and efficient and most of all the swamp cooler was repaired. The price they charged was excellent. I also signed up for a maintenance contract based on how well they took care of this problem. There are not a lot of places left who service swamp coolers so this was a good find. I have already recommended them to my sister for service on the air conditioning system in her home."

"Efficiency Air Inc is a fabulous company with excellent customer service and trained professional installers. I received a quote to install a mini split air conditioner/heat pump and we were overjoyed of the quality of work we received. They showed up on time and installed the system with ease. The install Manager â Deanâ was a true leader and got everything needed accomplished. I would recommend Dean and crew to anyone needing quality service. Thank you again for everything. Your lifetime customer Nathaniel G Santa Clarita, CA"

"Arrived on time and fixed the problem. A bit more expensive than I would have liked but checking around probably not much more than elsewhere and our air conditioner was fixed same day in the middle of a heat wave."

"⭐⭐⭐⭐⭐ We had an amazing experience with Ernie from Upright Construction! He came out to check our AC because it just wasn’t keeping up during this awful heat wave. From the moment he arrived, he was professional, honest, and took the time to explain exactly what was going on in a way we could understand. What really stood out was that he never tried to upsell us or pressure us into unnecessary repairs. It genuinely felt like he wanted to help us fix the problem instead of making an extra dollar, which is so hard to find these days. Thanks to Ernie, our AC is now working amazingly, and our house is finally cool again. We couldn’t be happier with the service we received and would absolutely recommend Ernie and Upright Construction to anyone looking for honest, reliable HVAC service!"

Air Conditioning FAQs, answered by experts

A window AC unit is not completely silent. You’ll hear the sound of air blowing, and if you put your ear right up next to the unit, you may hear a slight hiss or gurgle as the refrigerant flows through the system. That said, if your system is making a running water sound, a loud banging sound, a grinding sound, or physically vibrating, you may be facing an issue or malfunction with your AC unit.

If you’re shopping around for a rooftop AC unit, you may hear them referred to as “package units.” That’s because rooftop AC systems are all-in-one heating and cooling units that connect directly to your home’s ductwork. If your AC repair pro references a package unit, they are referring to the system on your roof.

The outdoor portions of air conditioners are designed to weather the rain, so you don’t need to worry about it. An awning or roof will help protect them from snow or falling debris, which can do more damage. This is true of both window AC and outdoor units for larger systems.

Set your house temperature between 55 and 85 degrees Fahrenheit while on vacation, depending on the season. If it’s winter, don’t go below 55 degrees. In the summer, the best AC temperature for energy savings is no higher than 85 degrees. You can save anywhere from 10% to 15% on your energy costs by adjusting the temperature while you’re away. If you have a smart thermostat, set up vacation modes for each season. On your way home, turn off vacation mode to allow the home to warm up or cool down before you arrive.

You can adjust uneven airflow in your home by adjusting the dampers on the vents. However, if the temperature feels consistent throughout the home, don’t worry too much about uneven airflow. Generally speaking, larger rooms should receive more airflow than smaller rooms, especially if they only have one vent.
