The lowest price is not always the best deal if it's not the most efficient because you could have higher energy costs. Then you need to sign a written proposal with the contractor you choose before he starts the effort because it will protect you by specifying the project costs, model numbers, job lifestyle and warranty information.
Regardless of how efficient your heating and cooling system is, you may be depreciating by having dirty or poorly planned ductwork available. In fact, it is a known fact that leaky duct work can reduce the efficiency of your cooling and heating system by as much as 20 %. *
While your HVAC equipment produces warm or cool air, your ductwork is what carries and disperses that air throughout your property. If joints aren't properly sealed and insulated, air can escape and result in more energy consumption to maintain your home heated or cooled.
Air duct sealing and insulation could be simple if they are in open areas. Repairs that are in enclosed spaces should be performed by a qualified professional, like the technicians at American Residential Services (ARS), serving Northern Virginia, Washington DC metropolitan and Md.
If you are concerned concerning efficiency of your ductwork, the following are options you should look:
1. Repair areas of leakage by finding sections in the ductwork that need to be joined that have come apart. You can do this visually, or by running your hand on the path of the ductwork to feel with regard to extreme hot and cold spots.
two. If you want to use duct tape for a air duct sealing, make sure it isn't tape that cracks, loses quality, or seems to lose its bond with age.
3. The ductwork in most homes is designed in one of two ways: radial or trunk and branch. Radial design is where your air items and returns are directly connected to your hvac system. Trunk and branch design is where supplies and returns branch aloof from one long piece of ductwork that is linked to the HVAC system (known as that "trunk". If you don't have such types of two systems in your home, you may want to consider converting your ductwork to one these two designs.
4. Make sure your air ducts are covered in areas where they run through parts of your house that are not heated or cooled. This can just give you another "layer" of protection so less air escapes.
5. While air duct cleaning has never been shown to actually prevent health conditions, you should have your ducts cleaned if you have such things as visible mold growth relating to the metal, rodents or insects live inside ones ductwork, or ducts are clogged with an abundance of dust and debris. ** The presence of these contaminants can mean an increase in the amount of harmful contaminants flowing through your air.

Heating, ventilation and air conditioning (HVAC) at home has a few principal functions. These basics include controlling the temperature, the humidity, and additionally maintaining the atmosphere quality. Heating and a / c systems are classified into two groups: Fundamental and local systems.
