What does HVAC actually mean?
HVAC (it’s pronounced as “H-vack”) is an acronym for Heating, Ventilation and Air Conditioning. The relation between the three functions of heating, ventilation, and air conditioning is very close because each of them helps to provide comfort, acceptable air quality indoors, and affordable costs of installation, operation, and maintenance. HVAC systems are usually used to provide proper ventilation, maintain pressure relationships, and reduce the filtration of air. Air and heating professionals usually go by the title “HVAC contractor,” and they can provide various HVAC operation and maintenance expertise and services.
How often should I replace the filter?
In truth, there’s no answer that works for everyone. The frequency with which you change your HVAC filter will depend largely on how much you make use of your air conditioning and heating systems, which in turn is influenced by the climate in your region. For instance, for folks that live in a busy downtown Philadelphia business, will most likely need to change their filter every month, as opposed to a home in a more rural area like Holland, Pa, where the air is cleaner can wait 2 to 3 months.
However, to know whether it’s time to change a filter, you just need to regularly monitor it.
What are the procedures for checking if my filter needs a change?
To start, make sure to check the filters of the system at least once every three weeks. Hold the filter that is currently being used to the light and compare it to a clean and unused filter. If the light that ideally should penetrate its spaces is obstructed by dust and dirt particles, and that would be an indicator that the filter needs to be changed.
When all else fails, it is recommended to at least change your filters at the start of heating and cooling seasons. Other times, the filters can be changed at your discretion and according to your need.
Why should I replace my working furnace or air conditioner?
While it is true that your present air conditioner or furnace might be functional, you should look into replacing it for a more effective system fit has been used for over 12 years. With a new air conditioning and heating system, you will have the opportunity to save close to 50% on your energy and utility costs, and you’ll also be able to make a significant amount of savings on heating repairs in the long-run.
What is the impact of the Clean Air Act on heating and cooling systems?
There is a section of the Clean Air Act that is related to the HVAC industry, and it encourages the development of eco-friendly alternatives for chemicals that contain chlorine (a substance that poses many threats to the Ozone layer). These chemicals are called hydrochlorofluorocarbons (or HCFCs, if you will). For instance, R-22, the preferred chemical refrigerant for over 40 years, is a major HCFC. Over the years, R-22 was used a lot in heat pumps and air conditioners’ condensing units to keep the temperatures of homes at a comfortable level. However, today, an ozone-friendly refrigerant known as R-410A has been developed as a safer alternative.
