Jose was amazing! I needed my thermostat replaced. He was quick, efficient and knew exactly what he was doing. I couldn’t ask for better service. I would highly recommend Jose to any one needing A/C service. ~ Christine J. Vista

Indoor Air Quality

Air Cleaning Systems, as homes become more energy-efficient, they are also becoming more susceptible to indoor air pollutants, due to the limited exchange of indoor air and fresh outdoor air. Failure to eliminate indoor air pollutants can cause flu-like symptoms such as headaches, and respiratory irritation, as well as aggravation of asthma and allergy conditions. The smallest dust particles that can cause the most irritation can only be removed with filtering devices. We can identify the important issues and provide a solution tailored to your specific need.

Air Purification systems can be stand-alone items or paired with air filtration units to address three distinct types of pollutants in the home – dust particles, microbes and toxic chemicals.

Going Green

Almost half of all energy you use at home is used by your climate control systems. Your system has to work exponentially harder if its air ducts or coils are dirty.

It is important to properly maintain your climate control systems with regular maintenance. This can help you increase energy efficiency while cutting back on your energy costs. Out of all of the ways you can go green while at home, a very simple and affordable way to do this is with a quick tune-up. We recommend tune-ups twice a year – in the spring, and in the fall.

We have been using “environmentally sound” refrigerant (PURON) since its inception. R-22 can no longer be used as of January 2010. So upgrading to a more efficient system, you can protect yourself from potentially higher cost of servicing your air conditioner or heating unit that uses R-22. There are many programs with rebates such as California Cash for Appliances, which has expanded to HVAC systems. Call for details or go to www.cash4appliances.org.
