You also need to be sure that after cleaning, that the filter has been given adequate time to dry to avoid any problems. Permanent filters should be cleaned and media replaced according to the manufacturer's instructions. Filters are all different and made for different needs. A cheap, disposable model may not filter enough dust and pollutants from the air to prevent the system from getting dirty and restricting air flow. The higher efficiency filters such as electronic air cleaner types not only remove a greater amount of dust but also can remove certain odors from within the home which can help those people with allergies and other respiratory conditions, or those who just wish to breathe cleaner air.
Some service companies advertise service calls for an unbelievable low price.
In today's economy, it is apparent that a company cannot perform quality service charging these types of rates. More than likely, your final repair bill will be much higher. Many of these companies charge a low rate for simply arriving at your home and once they arrive, they begin charging hourly labor rates. On the other hand, Berkeley Services performs all of its residential services using flat rate pricing which means that you will be quoted a price necessary to repair your system prior to the work being done. That means no pricing surprises at the end of service.
