While the summer heat has arrived, you tend to forget how fleeting it can be and how that can affect your decision to install central air conditioning this season or have your existing unit maintained. Most homeowners don’t realize that air conditioning can only be installed, serviced, or repaired when the outdoor temperature is at least 15 degrees Celsius. This is because air conditioning provides cool air using a liquid gas called refrigerant that must be pressurized in order for the unit to operate properly.
When temperatures are too cool, it is impossible to get correct temperature and pressure readings from your A/C compressor. Temperature and pressure readings from are required in order to properly install and set up a new unit,
Since the early 1990’s a radical shift has been taking place in the air conditioning industry. R-22 refrigerant – also known as Freon – has been completely phased out of production in favor of a superior refrigerant called R410a, also known as Puron. The reasons for this shift in refrigerant are mainly environmental. R-22 poses serious environmental risks as leaks in A/C compressors contribute to releasing hydrochloroflourocarbons (HFCF’s) into the air, depleting the ozone layer and contributing to greenhouse warming. R410a A/C compressors are also more energy efficient, another important factor when considering the environmental impact of home cooling.
Furnace filters were originally designed for protection. But with rising concerns for indoor air quality, high efficiency furnace filters with denser media are becoming the norm. Electrostatic filters, electronic air cleaners, HEPA filters, and allergen filters are sweeping the market and providing health benefits for homeowners. But that isn’t the whole picture.
While disposable filters do not provide significant indoor air quality benefits, they have provided homeowners with years of dependable performance by providing proficient air flow to the furnace. Air flow is the most important factor ensuring your furnace does not overheat which could cause costly mechanical damage. If indoor air quality is not a chief concern, many homeowners wonder is a high efficiency filter worth it? The answer may be no.
