I've been in the trades since I was 15, looking for opportunities to grow my buisness after moving to a new area recently. We generally are a group of full time contractors, engineers and project managers that like to get our hands dirty. We work fast, do everything in house, work flexible hours and pride ourselves on affordable pricing.

"I recently had the pleasure of working with Emerald Bay Design and Construction for a major renovation project, and I couldn't be more impressed with the craftsmanship. From start to finish, they demonstrated a deep understanding of design and construction techniques, delivering outstanding results that exceeded my expectations. Richard took the time to understand my vision and translated it into a beautifully crafted reality. Communication was clear and timely throughout the process and I received my bid back quickly and accurately. Overall, I would highly recommend Emerald Bay Design and Construction to anyone looking for a design and construction company. I am thrilled with the results of my project and look forward to working with them again in the future."

Heating and Air Conditioning questions, answered by experts

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.

As mentioned above, not all HVAC Schrader valves are necessarily the same. While the valve core and pin or spring size on Schrader valves used for HVAC are generally similar, the valves are not all universal and interchangeable. The size of Schrader valves varies depending on whether it's used in an air conditioner, bicycle tire, or motor vehicle tire.

There are ways to detect a refrigerant leak with several different testing methods. However, most homeowners can figure out something’s wrong with their AC unit by noticing these common signs:

  • Ice forming on the evaporator coil

  • Water leaks near the AC unit

  • Frequent hissing sounds

  • Increased electric bills

  • Unit takes longer than usual to cool

  • Unit is blowing hot air

If your whole house is cold that’s one thing, but what if you only have a few rooms that are cold? First, you need to determine why this may be happening. A good place to start is to investigate the potential causes listed in this article—heat transfer, airflow, thermostat problems, humidity, and insulation. Once you’ve narrowed down the issue, you’d apply the same principles to the cold rooms as you would to the entire home.

While 72 degrees is a comfortable setting for many people, it’s likely not the most efficient temperature setting for your air conditioning unit. By pushing the temperature up to 75 or 78 degrees, you stand to save money on your energy bill. That said, these temperatures may be too warm to be comfortable for some people and are definitely too warm for most people to sleep comfortably.
