Spring is a great time to own rental property. We can enjoy the warmer weather while working on our homes. Common tasks to knock out include landscaping, lawn mowing and clearing out any hidden trash from winter. However, one of the most important things you can do is often overlooked. Each spring, you should have a professional check your furnace and central airconditioning unit. This inspection should include the exterior condensing unit, the coil and all connections, lines, pumps, & drains. They should also change the furnace filter and clean the coil (if needed). This inspection, which shouldn't cost you much, is a little thing that can go a long way in both preventing problems before they.
