Are all Furnace Filters the Same?

heating repair Denver - Q&A

No, they are not. Actually, there are several types of furnace filters.

For proper operation, heating repair Denver furnace technicians tell us that the furnace needs accessories to protect it over time. For example, a gas furnace needs a regulator with a built-in dirt filter, mounted on the gas supply pipe.

Here are other types of filters that protect a furnace from impurities present in the thermal agent:

Anti-limescale filter

This filter acts through the magnetic field that dissociates the hard salt molecules, and the calcium crystals become a fine powder. The powder can no longer participate in the formation of limestone because it is kept in suspension. The anti-limescale filter can be: magnetic, with polyphosphates, with gel or electronic.

Y filter with sieve

This is a type of mechanical filter, installed in order to retain solid particles in the water. The Y filter protects the furnace from water impurities that come in contact with it. It is recommended to purchase a filter with cotton cartridge, as it is able to retain very fine impurities.

Cartridge filters have a simple principle – they consist of a polypropylene glass on which a washable sieve (made from nylon or cotton) is applied. Thus, the cartridge filter acts mechanically, by retaining residues in the water. The Y filter is installed on the cold water inlet pipe, before the anti-limescale filter. It protects the furnace from impurities in the heating circuit as well as from rust particles in the radiators. Therefore, this type of filter must be changed or cleaned at regular intervals (every 24 months).

Are A/C Warranties a Good Deal?

Image
For air conditioners there are two types of warranties: factory warranty covering the equipment and spare parts installation warranty from the installer, which refers to repairs related to installation, refrigerant route or electrical connections For your protection, air conditioning repair Denver technicians suggest that you insist on receiving a written warranty for both equipment and installation.

Will Air Conditioning Help Allergies?

Image
Although they can filter particles such as pollen, air conditioners may also become a suitable environment for the development and multiplication of organisms (viruses, bacteria), which can spread rapidly especially indoors. Also, this type of appliance emits aerosols – small particles of organic or inorganic origin – which have a strong allergenic effect. Because the air does not have the necessary humidity, it decreases the immune resistance of the airway mucosa and thus, we can get serious allergies and more. Air conditioners also reduce the body’s ability to defend itself and thus increase the risk of infections, the airways being among the first to be affected. Allergies and respiratory infections can be avoided if: The air conditioner is set to the temperature of 24-25 degrees C instead of 21- 22, as it is usually used. Do not install air conditioning in the bedrooms, but rather in the hallway, in order to cool the rooms indirectly. At work, make sure that desks are located ...
