Perhaps you are a DIY enthusiast or just a homeowner looking to do their next capital improvement project. If your home doesn’t already have an air conditioner for the brutal Colorado Summer heat, then it is almost certainly on the top of your list. Installing an ac is a large investment that provides ROI and immediate comfort to your home. But can you install an ac by yourself? How about a window ac or mini split? More importantly, are you even allowed to install ac, and do you need a permit? Let’s take a quick look at Denver and Arvada Guidelines, as well as, consult professional HVAC contractors like Fox Heating and Cooling for the answer!
Can I buy and install my own AC unit?
Simply put, no, you cannot replace your AC unit yourself.
Even if you have the technical skills and knowledge for installing an ac unit, the local municipalities like Denver and Arvada would not approve or issue a permit to anyone who is not licensed. Additionally, it might not be the greatest idea to perform a DIY install of an air conditioner due to the various factors and technical specifications related to an optimal HVAC system. It is best to leave it to the professionals to handle everything. With that said, do HVAC contractors need a permit for installing an ac?
Do I need a permit for installing an ac?
Yes, a licensed mechanical contractor or HVAC technician will need to apply and get approval from the local building department in order to install an ac for your home or dwelling.
According to the City of Denver, permits are required for the following single-family homes, duplexes, and garages:
- Compressor units
- Ductwork
- Evaporative cooling units
- Exhaust systems
- Fireplaces (prefab metal, gas log, gas piping, gas vent)
- Forced air heating systems
- Gas piping
- Make-up air units
- Range hoods
- Roof-top units (10 tons or less)
- Through-wall heaters
- Unit heaters
- Ventilating systems
- Water heaters
According to the City of Arvada, permits and inspections for residential installs and replacements for mechanical and plumbing appliances are required to be approved before work can start. This also includes the requirement for holding a current HVAC or Mechanical Contractor’s License. Arvada requires permits and approval for the following work:
- Furnace Installation
- Air Conditioning Installation
- Gas Log Fire Place Installation
- Gas Line Installation, replacement
- Evaporative Cooler Installation
- Boiler Installation
- Water Heater Installation
- Lawn Sprinkler Installation
- Water Conditioner
- Backflow Device
Do I need a permit to install a ductless mini split system?
Following the city guidelines, permits are also required for installing ductless mini-split systems. A permit will almost always be required to install a mini-split system. Usually, they are controlled at the county or city level, so there could be variations in the requirements and restrictions between different locations. There are codes laying out best practices for working on HVAC equipment, including mini-splits.
Do I need a permit to install a window ac?
Window ac are not required to have a permit or be inspected. But they are subject to building management and ownership for approval (if you are renting or a part of an HOA). These are viewed as simple appliances and are typically plugged into a standard outlet. Therefore, minimal training and knowledge are required. There are smaller and less efficient than a central air conditioner or mini split which is why many homeowners look to replace them frequently. If you are interested in replacing a window ac unit for a full air conditioning unit, please contact Fox Heating and Cooling for a free consultation and estimate.
