Whether you are planning the ultimate “man cave,” have a guesthouse or are renting out adjacent accessory structures, you’re going to need an HVAC system. Choosing the right HVAC unit and ensuring it’s well maintained is important to getting the most out of the system and ensuring it has a long life span. Here’s how to do it.

Central HVAC or Ductless System?

Don’t automatically assume you need a central HVAC unit for larger buildings or a wall AC unit for smaller accessory structures. Take a look at how many rooms you have and the floor layout, as well as if the building is only going to be used periodically or seasonally.

Sometimes your best HVAC bet is to go with a ductless mini split system. It offers a built-in zoning feature for each room, and their SEER ratings (cooling efficiency) are unbeatable. Their heating capacity is nothing to sneeze at either, with warming capabilities down to 15 degrees below zero.

HVAC Maintenance for Accessory Structures

Your new whole-home HVAC unit or ductless mini split system is going to need scheduled maintenance. Some tasks you can do yourself, and for others, you need to hire a professional HVAC technician.

  • Filters: Mark your calendar to make sure you clean or change the air filter as the manufacturer suggests.
  • Compressor/condenser: Maintain 3 feet of unrestricted airflow to the outdoor unit.
  • Air vents: Make sure airflow from each air vent is even and clear of obstructions. If airflow is uneven, you may need professional duct sealing or duct balancing.
  • Pro maintenance: Whether you have a whole-home HVAC unit or a ductless system for your accessory structures, the unit should be professionally serviced each spring and fall.

HVAC Contractors, Warranties, and Accessory Structures

Other key decisions on your plate for installing an HVAC unit are choosing the right HVAC contractor and warranty considerations. Get three estimates and check the customer ratings of each HVAC contractor. You want a reputable company that will be there for you start to finish for professional maintenance and one that offers a nice warranty.
