High Efficiency Air Conditioning
Air Conditioner Upgrades
Air conditioners typically account for 10% of a home’s energy use releasing an average of two tons of carbon dioxide into the environment every year. Upgrading to a high-efficiency air conditioner or installing a whole house fan will improve the efficiency of your home energy use by 20%–50%. This will reduce your utility bills while also making your home more comfortable for your family. Another benefit is that with more efficient air conditioning systems you reduce your carbon footprint.
Air Conditioner Service
Typically, an older home might contain an oversized and inefficient air conditioner compared to modern equipment. High efficiency equipment costs slightly more, but over time it pays for itself since you will have lower monthly electric bills. Additionally a correctly sized and properly installed cooling system will keep your home the temperature you want. This means a more comfortable home for your family. By installing an appropriately sized cooling system to your homes needs, sealing your ducts to reduce leakage and then balancing the air flow to each room, we achieve a very comfortable and efficient home.
Whole House Fans
In moderate climates like the SF Bay Area a whole house fan can often cool down a stuffy house quicker than central air conditioning. This depends on the exterior air being cooler than the air inside the house so a whole house fan would not be a good cooling solution in a climate like Los Angeles or Arizona. However for the Bay Area’s “Indian Summers” , often times the outdoor air will cool down very quickly the minute the sun sets whereas the house will still have warm stale inside. In situations like this whole house fans effectively cool down your home for much cheaper than central air. For many Bay Area homes, a whole house fan provides the most cost-effective and energy efficient solution to your home cooling needs
Air Conditioning Ducts
If your cold air return ducts has an air leak of 20% (getting air from somewhere other than your home such as the attic or crawlspace), it reduces your A/C output by 50%. A sealed duct system becomes essential for any cooling system to perform optimally. We can not overstate the importance of repairing the duct system as part of any air conditioner installation or repair. Installing a new air conditioner without making your the ducts are sealed is counter-productive and not produce the results you want no matter how efficient the air conditioner itself is.
Complete Home Cooling Solutions
By sealing your duct system, we can reduce the size of your cooling system and drastically reduce your energy need. Finally, a properly insulated home (attic, walls, floor) dramatically lowers the need for cooling in the first place. This allows us to install smaller but more efficient air conditioning systems, which saves on your initial investment cost AND your on-going operating costs.
