When our partner & I bought a historical home, the people I was with and I were honestly unhappy with the portable heating & cooling units. Because the walls in the beach lake house are exceptionally slim& constructed of plaster, installing a conventional duct method isn’t a viable option. The former owners managed temperature control with window a/cs & electric baseboard heaters. These heating & cooling units are noisy, unnattractive, inefficient & ineffective. In our local area, the people I was with and I deal with Wintertide temperatures below zero & excessive Summer heat & humidity. The lake house was uncomfortable just about all year round. I finally consulted a local Heating, Ventilation & A/C corporation for some help. She recommended the installation of a high-velocity Heating, Ventilation & A/C system. The compact size of the component & flexibility of the ducts allow this type of method to be retrofitted into existing homes separate from a huge renovation project. There’s no need to tear down walls or gut the home. The slimducts can be snaked between beams & joints, & the modular air handlers & coils can be installed into honestly compact spaces, such as the attic or even a crawl space. A high velocity Heating, Ventilation & A/C method takes up about a second of the space of a conventional system. I like that the heating & cooling component doesn’t detract from the historical integrity of the home. There was a lot of choices for vent styles, & the vents are round, honestly small & blend into the decor. Every one of us chose vents from unfinished wood that could be painted to perfectly match the surroundings. They are mounted into the ceiling & provide whisper-quiet airflow.
