Bottom line: After our repairs and adjustments, and in the midst of the heat wave, Carissa and her family reported that the system caught up and maintained a comfortable - lower than ever - temperature. On our first visit we discovered a failing high pressure safety switch that would trip, ...

On inspection of the system we noted the location of all supply and return ducts, registers and grilles. We noted the capacity of the system to determine airflow. Lastly we recorded static pressures before and after the filter and before and after the indoor coil. Taken together we found the ...

Liz has the only Daikin SkyAir system we have installed. This combines a variable speed ducted air handler with an inverter heat pump (outdoor unit). This equipment is used more often in commercial space than in residential but we worked together to select this equipment and it has performed wonderfully ...

Zephyr recently installed two new systems - a modulating heat pump for the bedroom level and a dual fuel (furnace and heat pump) for the main levels of the home. So we were excited to see the renovation and that our clients wanted to protect their equipment! So how do ...

We found that the primary system was low on refrigerant, which was the cause of the loss of cooling. We also found the condensate drain was plugged and the system had begun to leak water on the basement floor. Outside, we found the outdoor coil clogged with dirt. As it ...

We found a system short of refrigerant and with an extremely dirty outdoor coil, which limits the ability of the system to transfer heat from inside the home to outdoor air. We cleaned the outdoor coil and added refrigerant until we achieved manufacturer target numbers. Once we hit our target ...

We added R-410a refrigerant and an injectable leak sealant so the system will provide cooling comfort. We also reviewed our records and noted that this is the second sealant injection we have added and the second year in a row we added refrigerant. Based on this we had a ...

We replaced all of the ducts in the crawl space with air-sealed and R-8.0 insulated hard metal ducts to include new through the floor connections. Our goal was to improve air flow to the main level while maintaining air flow to the upper level. We also wanted to reduce total ...

We began with a whole house blower door test and infrared camera review. The objective was less to discover the total air leakage of the house but to find the pathway of the air from outdoors to in-between to finished levels of Erik's home. We were able to identify several ...

On arrival we found the outdoor unit not operating, as the client described. On inspection we found the outdoor contactor (the switch passing power to the unit) to be frozen. In this case, the contactor would freeze in whatever position it was in - open: system not working; close it ...

During our maintenance visits, we recharged the system according to manufacturer specifications and eliminated the likely leak locations. As the system continued to leak refrigerant we identified the lineset connecting the indoor and outdoor units as the likely culprit. Working with the client, we set up a test to isolate ...

We arrived to inspect the system and found a dirty flame sensor. We were able to clean and replace it and return the system to normal service. We also discussed how our maintenance program is designed to catch and minimize the likelihood of a nuisance service issue during those coldest ...

On our first visit we found the furnace board displaying a fault code for a stuck pressure switch. On reset, the furnace functioned properly. Through several cycles we could not replicate the problem. Several days later, the problem we recurred so we returned with a replacement pressure switch. We calibrated ...

We diagnosed a failed pressure switch and board as the cause of no heat. We also identified a failing inducer motor - high amperage draw and a grinding sound on start-up and as it ran. We replaced all components and returned the system to service. As part of our normal ...
