In Massachusetts heat pump incentives and a flood of unqualified contractors have resulted in both municipalities and incentive programs cracking down on the sizing and design of heat pump systems. I'd be happy to talk about how we use technology to both ensure of accuracy and to better educate homeowners while we're doing an initial consultation in their home.
I deal with renovations in which electrical systems satisfy HVAC needs, and challenging retrofits seem to be a common aspect in my practice. The most difficult task was trying to install a complete modern HVAC system into a block that was ageing, and the design no longer fit into any existing standard, and nothing could be moved, as the owner would not allow structural or electrical rewiring of the building. The team took days to map the old paths, and we continued to change duct runs until the volume of air flowing was of the required magnitude due to the load calculations. BUs ' access was required to be strictly timed. We moved through the building by passing through very tight windows and ensuring that each access had been closed before a new one opened and the system was allowed to display readings after the last tests were clear. The truck was equally important as the planning since there was no need to go out to find any tools. Most of the work was done by the refrigerant recovery equipment, the electronic gauges and the thermal camera and the crew used them to monitor leaks and ensure the effectiveness of the run before proceeding to the next area. As we work, my team records the sequence of each job to allow their repeated by other crews in the future, and prevent the delays of slow detours that are visible in older buildings.
