Should You Consider a Residential Rooftop HVAC Unit?

If you’re in the market for new cooling equipment, you might wonder whether a rooftop HVAC unit is a good choice for your home.

Rooftop units have been installed on commercial buildings for decades, and they’re becoming more popular for residential use in warmer climates, where heating isn’t a priority. Rooftop HVAC installations are seldom seen on residential roofs here in Monmouth County, and here are a couple of facts about the units that help explain why:

  • Rooftop units are stand-alone systems. Rooftop HVAC or “packaged units” have the compressor, fans, evaporator and condenser coils contained in a single cabinet, and they’re ducted down through the roof/attic and ceilings.
  • Flat roofs are ideal for HVAC equipment installations. If you’ve noticed rooftop HVAC units on a commercial building, it likely has a flat roof that provides a level installation site and ample structural support.

Factors to Consider About Rooftop HVAC

If you still think that installing new cooling equipment on the roof of your home might be a viable option, you need to consider these additional factors:

  • If your home has a pitched roof, you’ll likely face the added cost of having a platform constructed that’s specifically designed to support the unit’s weight.
  • Installing a rooftop HVAC unit can end up costing a lot more than a traditional split-system or ductless mini-splits if your home currently has a forced-air system, hot water baseboard, or in-floor radiant heating.
  • HVAC care will be less convenient and more hazardous, because your technician will have to climb up on the roof whenever the system’s air filter needs replacement, when it’s time to perform preventive maintenance, or if a problem develops that needs investigation or repair.
  • When your costly HVAC equipment sits fully exposed up on the roof, it’s at greater risk of wear/damage from the elements and storms.
  • If none of the other homes in your neighborhood have rooftop HVAC units, installing one could affect your home’s value if you decide to sell.
