PTACs, short for Packaged Terminal Air Conditioners, are commercial-grade air conditioners installed through a wall. PTACs are commonly placed through an external wall right above the floor and often under a window. Most models include both cooling and heating, and their durable construction makes them popular in the hospitality industry. They're built with parts to hold up against tough outdoor environmental conditions and are designed for quick, convenient cooling and heating. While PTAC air conditioning units are most commonly used in hotels, they can also be found in sun rooms, offices, and assisted living facilities. Hotel managers and owners carefully consider their HVAC choices in terms of value and profitability. In the lodging industry, energy costs—particularly on heating—is one of the fastest-growing operating costs. Additionally, loud and ineffective ACs always top the list of customer complaints. Many hotels are replacing old, inefficient PTACs with new, more energy-efficient models to save on energy costs.

These newer models are built with better insulation for quieter operation; a more durable exterior to last longer; and include efficient heat pumps to reduce costs during heating. The combination of these factors makes PTACs popular in hotels and assisted living facilities. These tough models, which allow each room to be set to different temperatures, are also simple to operate. Most of them come with digital control boards that let you quickly set your ideal temperature and make other setting changes in mere seconds. PTACs can use 2 types of heat: electric heat or heat pump. Models with electric heat use electricity and a heating element that warms air as it passes over the element. A strong fan then disperses this warm air around your space, similar to cool air while in AC mode. Other models, however, use heat pumps, which simply reverse the cooling cycle to transfer warm air into your space.  This type of heating is more efficient and is popular in warmer climates (since it only works down to 40 degrees F).

Most PTAC models come with heat pumps and an electric heat back up for particularly cold parts of the year. The cooling capacity of a room air conditioner is measured in British Thermal Units (BTUs) per hour. To ensure high efficiency, choose an air conditioner with a BTU level designed to fit the square footage of your room or space. central ac units for saleThis is necessary to avoid a few common scenarios: If you use an air conditioner that doesn't have enough BTU power to cover your room, it will work overtime to bring the temperature down. cheap central air conditioner unitsIn the process, energy dollars will be wasted.how much unit does ac consume In contrast, an AC that has too large of a BTU capacity for your space will cool it, but it won't remove as much humidity from the air as a properly-sized unit.

This will make your room feel damp and clammy. Confirm your PTAC model is the appropriate size for the room or suite you're cooling. The chart below can be used as a guide for how many BTUs you need for particular room sizes. These are the standard PTAC sizes but can vary slightly depending on brand and environmental conditions: PTACs are large, commercial-grade products that often require more powerful voltage than the standard 115-volt outlet. Most PTACs we carry here at Sylvane require 220-240 volts and a 6-20P plug face. Make sure your room is wired to handle this voltage if that's what your model requires. This information should be listed in the specifications on each product page. PTAC AC units' efficiency is measured by their Energy Efficiency Ratio (EER). The higher the EER, the more efficient the model is. Be sure to compare your model's EER to others you're considering. As previously mentioned, efficient PTAC air conditioners can save you money on operation and energy costs.

Additionally, PTAC AC units with heat pumps tend to be more efficient than those that offer electric heat. A wall sleeve and external grille must be purchased separately if you're using a PTAC for new construction. If you're simply replacing an old or outdated unit, you may be able to use your existing sleeve and grille depending upon its size and condition. Nearly all PTAC models are 42-inches wide, but be sure to check your dimensions before using an existing sleeve for a new model.

During a service call, an AC retrofit for a condensing unit, commercial, rooftop, or residential system is an opportunity to grow your bottom line.

An AC retrofit is a valuable service to your customers, particularly for: Systems with little or no refrigerant charge Systems requiring replacement of a component Environmentally focused customers with a desire for non-ozone-depleting refrigerants Customers who would prefer an AC retrofit rather than an entire system replacement Systems with lines buried in walls/floors that cannot be converted to R-410A Customers unable to afford a new R-410A system in the current economy What do these scenarios have in common? They are all opportunities for an AC retrofit from R-22 to Freon™ MO99, the non-ozone-depleting, mineral oil compatible R-22, alternative from Chemours. A Quick and Non-Disruptive Change No oil change required; Freon™ MO99 is compatible with mineral oil, AB, and POE No cutting out of compressors to dump oil No TXV or line set changes Pressure and temperatures closely match R-22 After making required repairs and changing seals and filter driers, simply evacuate and charge with Freon™ MO99

Freon™ MO99 is a non-ozone-depleting and more sustainable solution Retrofitting to Freon™ MO99 now eliminates exposure to possible R-22 supply issues Helps avoid potential R-22 price volatility Eliminates risks for HCFC leak reporting/fines Extends useful life of equipment Avoids additional service call for an AC retrofit When the system is down and the refrigerant charge is removed is the ideal opportunity to explain the clear benefits of converting your customer away from R-22. Note: Please consult and follow the Freon™ MO99 retrofit guidelines for detailed step-by-step instructions for your AC retrofit. Freon™ MO99 is a versatile R-22 replacement refrigerant for replacing R-22 in direct expansion (DX) air conditioning and refrigeration systems that can be easily used in an AC retrofit. Freon™ MO99 has been specifically formulated to combine R-22 pressure-enthalpy characteristics with mineral oil compatibility in a unique refrigerant that can be used to replace R-22 over a wide range of evaporator temperatures.

Freon™ MO99 is compatible with MO/AB/POE lubricants; in most cases, no change of lubricant type is required during the AC retrofit. Refrigeration (low- and medium-temperature) Lower retrofit labor costs versus HFC/POE options Eliminates costly and disruptive oil changes Compatible with AB, MO, and POE lubricants No expansion valve or line set changes Minimizes time spent on control set point adjustments and subsequent service calls Not subject to phaseout under the Montreal Protocol 42% lower global warming potential (GWP) than R-404A (ref. AR4 report) After the AC retrofit, can be topped off during service without removing the entire charge Based on field experience, calorimeter testing, and thermodynamic property data, Freon™ MO99 provides similar cooling capacity and energy efficiency versus R-22 in most systems, while operating at a lower compressor discharge temperature. Actual performance depends on system design and operating conditions.
