Ductless mini-split HVAC is much more attractive in a country without skilled labor?
We still own our condo in Harvard Square (rented out on AirBnB; will sell once coronapanic ends in Maskachusetts and people realize that living in the suburbs while working in the city is intolerable due to traffic (but maybe coronapanic will never end?)). It has a traditional HVAC system with air handler, ducts, and a condenser outside. The contractors in the Boston area that are qualified to do basic maintenance on the system are all too busy to do maintenance (they’re happy to do a $20,000 installation project). But these types of systems need annual maintenance to avoid the risk of a drain backup and massive water leak inside the house.
A contractor here in Florida, where A/C maintenance is much more available, said that he’s never seen a mini-split suffer from a clogged drain. For some reason they don’t build up gunk inside the lines the way that traditional systems do. As the U.S. population grows while the population of skilled laborers stays constant or shrinks (we are growing our population via low-skill labor and/or asylum-seekers who don’t work at all (babies, parents of young kids, the elderly), not with migrants who have HVAC training), the problem of finding qualified service people will only get worse. I wonder if this is a good argument for ductless mini-split heat pumps. As long as there are factories in Japan and China, replacement components will be available and the overall system complexity and annual maintenance needs are much reduced compared to a traditional HVAC system.
(The Florida contractor’s favorite brand is GREE, founded 1991 in Guangdong.)
Readers: What is the argument for installing a traditional HVAC system? Easier to filter and humidify the air if desired? Lower fan noise in the interior?
