Trusted Chimney Sweep, Air Duct & Dryer Vent Cleaning in Spring, TX

You should never close more than one register in your home if the air conditioning system was installed by ACT. If your duct system was not installed by ACT, you should not close any registers. Closing off registers does not save energy! Find out about a temperature zoning system. If you shut off air to rooms, they still will have heat gain from the outside. This heat gain is transfers to the rest of the house through doors, walls, ceilings, etc. This heat gain will cause your unit to work just as hard as if all the registers were open. There are no energy savings to be gained from closing off registers.

Absolutely not. Never cover registers or return grills with any material what-so-ever. Doing this adds resistance to the system, causing your unit to work harder and your energy bills to rise. Your system was designed to operate with all registers fully open and unblocked.

Your furnace smells because dust has accumulated on the heat exchanger inside the furnace. The smell is the dust being burnt off. Under normal conditions, this smell should stop coming from the furnace within 24-48 hours.

The refrigerant in your system should never have to be changed. Refrigerant is not like oil in a car. It only has to be replaced if it becomes contaminated from an outside source. Even if this happens, your refrigerant can often be filtered to remove contaminants.

If you have a newer unit, you don't have to oil the motor because they are sealed bearing and can't be oiled. If your unit is older and does not have sealed bearing motors, you should oil them or have them oiled with a drop or two of oil once yearly.
