• Seasonal Preventive Maintenance

    Bi-yearly preventive maintenance cleanings are a good investment for every home owner. Before the chill of the autumn comes, you should schedule your fall preventive maintenance cleaning for your Heat Pumps , Gas Furnaces , Gas Boilers , or Oil Furnaces & Boilers . Preventive maintenance cleanings keep your heating and air conditioning systems running more efficiently. Without these cleanings heating and air conditioning systems can wear themselves out. When HVAC systems wear out, they have the potential of pumping carbon monoxide into your home. They also have more problems and a greater expectation of breakdowns and failures.

    • Servicing Boilers & Furnaces

    The most extensive Preventive Maintenance cleanings are done on Oil Boiler and Oil Furnaces. Oil can cause compulsion causing them to become dirtier. Basic cleanings for Gas or Propane are similar; in both systems the fuel mixes with air and ignites, heating the steel chamber. This creates the fresh filtered air that will then blow outside the hot chamber and into the heating ducts. When you see home with radiators they have boilers that heat hot water rather than air.

    Although heating and air conditioning systems vary, the preventive maintenance cleanings are similar. All HVAC systems vent the dangerous exhaust out a chimney or flue.

  • Beat the Heat!

    These first few weeks of Summer have felt surprisingly hot and humid. The Mid-Atlantic region of the United States, which the greater Chester County area is located within, has been struck with three unanticipated heat waves in the past two weeks. Temperatures remained at or over 90 degrees for over four days in a row. The surrounding days were in the mid or high 80’s. These were record high temperatures for this area. The last time a temperature was recorded this high during this time of year was 1985.

    It is important that homeowners are prepared for unanticipated heat waves. This means that your air conditioning system is up and running smoothly when you need it most. But – how can you make sure that it is up and running smoothly before a heat wave hits?

    1. Test Run

    You can start by test running your system. Turn it on before it gets hot and see if you can troubleshoot any problems. If there are any problems, this will give you ample time to seek professional help before it gets too hot. When contacting a technician during an off season you will have a wider range of times to schedule your appointment and will receive quicker service. This can be very beneficial for those who have very busy schedules. So remember – it’s all about timing!

    1. Preventative Maintenance

    Preventative Maintenance should be performed once a year on your Air Conditioning system during the Spring or Summer months. Preventative maintenance cleaning ensures that your air conditioning system are clean and running efficiently. When performing preventative maintenance technicians check a variety of features to ensure that the system is running smoothly. This includes checking operating pressures and temperatures, the thermostat, pumps, cleaning of condenser and evaporating coilers, changing nozzles, lubricating parts, and inspecting equipment for leaks.

    Preventative maintenance also includes the changing or cleaning of filters. This is very important, especially if you have pets or a lot of dust in your home. If you don’t change your filter it can disperse sickness, germs, dust, and dander into the air of your home. You can purchase your filter before your technician arrives at your scheduled appointment. You can find filters easily online at www.filters.com or at home improvement stores such as Home Depot or Lowe’s.
