Air filtration systems work by trapping contaminant particles on a medium such as fiberglass. While your forced–air system already has one or more air filters, those are designed to protect the system components from particles, rather than remove them from your indoor air. We not only install air filtration systems in Federal Way; we also repair and maintain them as necessary.
Great service, Brandon did a job great job explaining eveything he was doing and showed me all issues and concerns I may have had beyond my initial problem of a clogged drain that responded to. He also did a great job in resolving my repair needs and installation of needed parts to maintain our AC unit. I now have a AC person I trust and can rely on for the future for both repair and maintenance. Thank you Brandon and A team Mechanical for the prompt response and after hour service.

When Asad came to service my furnace, he said it needed a new thermostat. I told him I ordered on on Amazon, and he said he would schedule a time to install it. I've tried calling him to schedule a service time, but he doesn't call back and can't schedule a time to install the thermostat. The business card he handed out only has his first name on it and no business address. Very Shady.

Ruud, Trane, and American Standard are among the more reliable natural gas furnace brands, whereas Goodman, Lennox, and Amana are among the less reliable brands. York, however, stands out as the least reliable brand and cannot be recommended by Consumer Reports at this time. That’s what we found based on the feedback of 21,618 subscribers, who reported on their experiences with gas furnaces installed between 2011 and 2016.

This feature uses a number of thermostats, a sophisticated central controller, and a series of dampers that control airflow to deliver different amounts of heating or cooling to different parts of the home. The larger the home, as a rule, the more useful zoning is. That's especially true if sections of the home have different heating or cooling requirements, because of wide variations in the number or type of windows, for example. But contractors we interviewed said that furnaces connected to zoned ductwork generally require more repair.
High-efficiency condensing furnaces (90% AFUE and above) are a bit more complex than conventional furnaces. The main differences between a conventional and condensing furnace is the heat exchanger technology used to extract heat from the combustion process and the method used to exhaust the combustion gases. In these ways, the furnaces are very different. The condensing furnace does not have a significantly more efficient combustion process than does a conventional furnace; both use gas burners with electronic ignition. The difference lies in that the condensing furnace has a more efficient heat extraction process after combustion.
