What we did
For this Lexington homeowner, we installed a heat pump to replace the existing system. Part of the work happened under the house, where an abandoned furnace was still sitting. We removed it so we had proper access to do the installation right, rather than working around old equipment that was no longer in use.
To make room for the work, we temporarily cut out a drain line. We ran new 10-inch flex pipe and used insulating bubble foil as part of the installation, which helps the system hold on to the air it conditions. We finished by installing a replacement filter so the new heat pump started out with clean airflow.
The space under a house can collect retired equipment over the years, and clearing it out makes future service easier as well. Insulating materials matter in a space that is not conditioned, since heated or cooled air passing through it can lose temperature before it reaches the rooms. A fresh filter at startup is a small step, but it protects the new equipment from the first day. If you are planning a heat pump change and have old equipment in the way, we can look at the space and talk through what needs to come out.
