Heat Pump Installation in the City of Westmount
Dear Westmount Residents,
At AirGreen, we take pride in providing top-notch air conditioning and heat pump services. We understand that every borough has its unique requirements, and Westmount is no exception. Here's a detailed guide on the rules and regulations for heat pump installations in your lovely borough.
1. Tonnage Limit:
- For any attached or semi-detached residential building, the cooling capacity of the unit should not exceed 550 sq.ft/ton. This measurement is based on the total floor area of your residence.
2. Installation:
- If you're considering installing your unit on the roof, please note that it should be mounted on a spring anti-vibration system. The static deflection should be 1 inch for residential units and 2 inches for commercial units.
- For units that require ventilation ducts, flexible joints must be added where the ducts meet the unit.
- Any contact with a party wall must be avoided, whether it's for the anchors or the exchange ducts. If contact is inevitable, a resilient anchor must be used.
3. Application Procedure:
- If your project alters the exterior of your property, it falls under the Site Planning and Architectural Integration Programs (SPAIP) regulation and requires approval from the city council. However, restoration works or identical replacements are exempted.
4. Required Documents:
- A letter detailing the proposed works.
- Owner's authorization if the application is made by a third party.
- Authorization from the co-owner's association.
- A recent location certificate.
- Technical sheet of the units, including dimensions and noise level.
- Description of the anti-vibration system if the unit is installed on the roof.
- Total area of the residence to determine the tonnage limit.
5. Associated Fees:
- A $55 analysis fee is required to open your file. The permit cost will be calculated based on the total cost of the works.
- Please note that only repair files are analyzed by the urban planning service. All others are transferred to the urban planning advisory committee and the city council.
6. Permit Issuance:
- Even after approval, the issuance of the permit is not immediate. Additional documents might be required, such as an official cost estimate or other specific forms.
Important Note: While we're always here to guide and assist you, it's the responsibility of each client to ensure compliance with all rules and to obtain agreement from their neighbors if necessary. Unless otherwise stated in our contract, obtaining the permit remains the client's responsibility. We encourage you to reach out to us with any questions or concerns.
Thank you for trusting us with your air conditioning and heat pump needs in Westmount. We look forward to working with you.
Warm regards, The AirGreen Team.
