From units installed upside down to the use cardboard plenums some air conditioning installation mistakes are just too common and often lead to problems. More often than not, these installation blunders are done by the inexperienced HVAC installation professionals. Knowing them can help you avoid problems in advance. Take a look at six of the common mistakes.
1) Improperly Sized System
Failure to correctly size the air condition system or its individual parts can lead to a dysfunctional system. It is important to under the different sizes to have a proper load calculation for the job. It starts with inspecting the home to determine the suitable AC system to install and the installation parameters. The installation contractor should take measurements of the floors, windows, ceilings, and wall to identify the suitable R-value and then calculate the system’s load using a computer.
2) Inadequately Sized Ductwork
The ductwork should be in proportion to the AC system. Improperly sized ducts are a common blunder, and such ductwork often has a similar case with its register. The right installation of the duct should be based on the load calculation. Having undersized supply or return air ducts can impede the efficiency of the compressor thus overworking it and leading to quick wear and tear and high energy bills.
3) Awkwardly Sealed Ducts
Poor sealing of the ductwork will lead to leaks which then leads to the loss of valuable heat or cooling air in certain sections of the home. It can also have the compressor work double-time yet no desired effects are seen.
4) Badly Installed Drains
Inexperienced air conditioning contractors can at times fail to install drain lines and drains with a proper emergency overflow pan. Such an installation will often have leaks noted through the wall and ceiling because the main drain was not installed correctly. Drafting of the sewer gasses is among the other unpleasant problems associated with condensate drains that have not been installed according to the set Air Conditioning Installation Mechanical Code.
5) Poor Air Quality
Carpet, mold, resins, mildew and pollen are some of the external factors that may lead to poor indoor air quality; and these should be factored in when installing the AC system. For instance, an oversized unit can be affected by this external factors and start having high humidity or poor air turnover. As such, the air conditioning installation should include the additional accessories that protect the system from these contaminants.
6) Refrigerant Leaks
Even when installing a new HVAC system, it is important to recheck the refrigerant levels to ensure the coolant will work for the AC system as per the load calculation. Any loss, even if it is less than 10% can add up to an increase of more than 20% in the utility bills; and this goes up significantly if there are any refrigerant leaks or inadequate levels of the coolant in the AC system during installation. The coolant leaks can also lead to undue wear and tear.
Many of the problems with air conditioners are often simple mistakes that go unnoticed by the installers according to http://altitudecomfort.com/air-conditioning-installation-denver.php, the website of one of the top air conditioning companies in Denver. Hiring a reputable and experienced contractor is thus the best option, and this applies when installing a new air conditioning system, or have the problems fixed.
