Air Conditioning Contra Costa If you are a homeowner then you most likely have an Air Conditioner. Home air conditioning in the summer makes up a large portion of your monthly utility bills. Equipment that operates efficiently while also providing stellar performance is a requirement. Stewarts offers routine maintenance plans that are applicable to any brand of air conditioner (or heat pump) you may own. An A/C is similar to your automobile - regular maintenance is required to keep it running efficiently and avoid expensive break downs. Eventually your cooling system's lifespan will approach an end and upgrading to a new unit will offer significant savings on utility costs. The efficiency of an air conditioner is rated by a SEER rating. The higher the SEER rating the more efficiency you'll experience. If your air conditioner is older and you'd like to know the cost and savings of a new unit, simply ask us for a FREE Estimate and we will come out to inspect your setup and let you know what options would be perfect for your specific needs!

Heating Contra Costa A furnace fulfills two important roles in your home: 1) It provides warm air in the cooler months and 2) it circulates air through the ductwork in your home. Even in the warmer seasons a furnace affects the quality and efficiency of your cooling system. The efficiency rating of a gas furnace is determined by an AFUE rating. The higher the number the more efficient the furnace (aim for the high 90's). A variable speed fan also provides more efficient operation and better air flow control. When a furnace is equipped with a variable speed fan, your home will be more comfortable and your system will offer quieter operation along with lower energy consumption. Again, this doesn't just affect warm air in the winter, but cool air in the summer months as well!

HVAC Installation, Repair & Maintenance High SEER and AFUE ratings on equipment is good and note worthy, albeit the most important part of reliable and efficient indoor comfort control is proper installation and maintenance. Those that skimp on the design and installation of their home system end up paying for that decision for many years to come. Poor design and install means higher utility bills and decreased performance. One must obtain service from an A/C contractor who has the experience, training and industry certifications to do the job right, and that is where we come to save the day!
