On this heating (PTU) precision tune up our Service Advisor, Thim performed maintenance and cleaned this furnace to ensure that the customer's comfort was at it's full potential.  

As you can see - cleaning and proper maintenance of your system is necessary.  Crawl spaces can be nasty, wet, dirty, moisture driven places that can hurt your heating and cooling system.  Having a scheduled tune up twice a year on a energy savings maintenance agreement (ESA) can prolong the life of your system.

During this visit your service advisor tightened all electrical connections, verified all high voltage levels, verified all control voltage levels, tested all motors and compressor ( if applicable)  to ensure amp draws are within proper range, and inspected all safeties for proper operation. We verified all start assists were within factory recommended range, inspected ductwork, and verified input and output levels on gas valve. We verified temperature difference across evaporator coil or heat exchanger, and visually inspected burners, and heat exchanger. We verified proper operation of auxiliary heat strips (if applicable). We inspected all fan wheels and blades for debris, cracks, balance, vacuumed out burner and blower compartment, and verified thermostat operation. We changed air filters if covered by the agreement, and cleaned up around equipment after the precision tune up was completed. We will also be checking all gas appliances to ensure that there are no carbon monoxide dangers at this time. We will check fire extinguishers, dryer vents, and test the batteries in all smoke detectors and carbon monoxide detectors. Your Service Advisor may have listed repair or system enhancement options for future reference that could potentially enhance your comfort, health & safety, extend the life of the equipment or help prevent excessively high utility bills.

Air Sealing, Insulation and Radiant Barrier - In your Attic - Photo 1
Attic Installation of New Heating System

Installations of new heating and air conditioning systems aren't always the easiest.  In fact, it is also hard to take good pictures as well.  Attic working conditions don't leave the best of senerios for working, our guys installed this one on a 86 degree day, which in an attic gets over 120 degrees (and thats a cool attic).  Attics involve tight working spaces, hot temperates, and also hard access. 

These photos are from a recent job showing the working situations that we do on a daily basis.  Imagine weaving duct work through this attic all while not falling through the ceiling.
