Preformed heating maintenance on 6 propane gas systems. We tested all electrical components and safeties for each system. All electrical components and safeties were testing within manufacturer specifications. We ran air advice to test air quality throughout the home. All reports came back with positive feedback. The client did mention that her allergies were becoming an issue. We provided estimates for a duct cleaning for the master bed room, the second master bedroom and installing an air scrubber on the first master bedroom unit to help combat the allergens. Units were back to cooling upon departure.
