FAQs Answered for You

  • What is the two-stage cooling process?

Answer: The Two-Stage process for cooling involves the use of a compressor with two different speeds. This allows the users access to 2 varying levels of AC operation depending entirely upon the cooling requirements. You can either go with the high speed or full capacity during hot summer days or opt for the low speed/partial capacity for days when the temperature is bearable. This can be an amazing and energy-efficient option as compared to the traditional variant of single-stage/single-speed units.

However, you need to keep in mind the fact that the two-stage machines generally have a longer cycle for operation. But this ensures that you save a lot on your energy consumption. It also helps remove excess humidity, or moisture from the house’s indoors, thus catering more comfort. In case there is an issue with your system, you can always seek help from certified service providers for complete HVAC repair or cooling/heating repair, Plano, TX.

  • What is the variable speed-based cooling/heating?

Answer: Variable speed heating or cooling is driven by the compressors or heat pumps with variable speed. This provides a highly-efficient system performance for both cooling and heating. You will eventually see a significant drop in your energy bills with improved comfort indoors.

  • What is the modulated form of heating?

Answer: The gas furnace that comes with a modulating form of gas valve with variable speed blowers can be an outstanding investment with economic performance in terms of heating. As opposed to the gas furnaces that are single-staged, these modulating heating furnaces have been designed to work at the minimum while providing optimum comfort. These machines tend to produce just the perfect amount of warm air in order to maintain a comfortable and steady temperature inside the house. However, with variable speeds in the scenario, there could be instances when your system fails. In such cases, you need to get in touch with a professional for heating repair, Plano, TX. You can surely avoid an emergency breakdown by opting for timely maintenance.

  • Do I need to zone my home?

Answer: When you install a ducted system in your house, the zoning process helps you divide the home into specific areas with regards to cooling and heating requirements. In order to zone the home into proper sections, you need to use zone dampers and secondary thermostats throughout the home’s duct system. Zoning helps you save a lot on your electricity bills. Say, for example, you frequently stay in your bedroom and rarely use the dining area. In such cases, switching off the heat or cooling in the dining is the best move. Here, the zoning process helps you by keeping the bedroom at your set temperature while cutting down or reducing the flow in the less frequented area. If you have been experiencing issues with the zoning system, you can always schedule a maintenance or repair session with heating repair, Plano, TX.

  • What is AFUE? 

Answer: The AFUE or Annual Fuel Utilization Efficiency is the percentage assigned for the rating of the efficiency of the furnace. It is calculated by dividing the heat ratio output by the heat input. This particular measurement unit describes the fuel efficiency of the system. In simple terms, it provides a number for the amount of propane or natural gas used by the system in order to produce enough heat from the furnace. With an increase in the AFUE, you can ensure that your system is highly efficient.

  • What is HSPF?

Answer: The term HSPF is an abbreviated version of the phrase Heating Seasonal Performance Factor. This number helps identify the efficiency of your heat pump. The higher the system’s HSPF number, the better your heating performance and efficiency. Always monitor this number to ensure that it is always at its highest. If you have been experiencing high bills instead of having a system with high HSPF, you should definitely get in touch with service providers for heating repair, Plano, TX, to rule out any major issues with your heating system.
