Questions to Ask Before Hiring an HVAC Contractor in the City of Seattle

The average cost of electricity for households in Seattle is currently 11.7 cents per kilowatt-hour (kWh), but heating and cooling energy consumption make up almost half of the total utility bill. Regular equipment maintenance, energy-efficient upgrades with proper installation, and applying the recommended insulation, air sealing, and thermostat settings can save about 30 percent on your energy bill while reducing environmental emissions. HVAC system maintenance, repair, and installation are best left to qualified professionals to ensure optimum efficiency. Therefore, when looking for HVAC contractors near you, it is advisable to do your due diligence to confirm the technician is competent to complete your job. You can do this by asking the following questions:

Are You Licensed to Practice as an HVAC Contractor in the City of Seattle?

Individuals who wish to engage in the business of installation, repair, alteration, servicing, and operation of refrigeration and air conditioning systems in Seattle must be duly licensed by the Seattle Department of Construction & Inspections. Carrying out these types of work without the required license is a violation that attracts civil penalties not exceeding $500 per day.

The city's Department of Construction & Inspection issues refrigeration operating engineer license, journey refrigeration mechanic license, and refrigeration and air conditioning contractor's license to interested parties. For refrigeration and air conditioning contractors and journey refrigeration mechanics license applicants, they can obtain any of the following three classes of licenses:

  • Class A -- Covering refrigeration machines using only sulfur dioxide and methyl chloride
  • Class B -- Covering refrigerating machines using all other refrigerants
  • Class C -- Covering all refrigerating machines using refrigerants included in Classes A and B

Applicants for any of the licenses mentioned above must pass a licensing examination to determine the qualifications for their desired license. Note that journey refrigeration mechanics applying for other types of licenses must furnish the Department with proof of three years of full-time experience as a journey refrigeration mechanic. Alternatively, such applicants must provide proof of training for at least one year in a recognized technology school. Once applicants pass the licensing examination, they can apply for the relevant licenses on a form prescribed by the Director of the Department. The application must be accompanied by a receipt showing payment of the applicable fees. For assistance with obtaining a license and other certification-related inquiries, applicants can contact the Department of Construction & Inspection at (206) 684-5174. To verify if your intended HVAC contractor has been duly licensed, you can use the Find Trade Licenses by Last Name platform provided by the city's Department of Construction & Inspection.

In addition to city-specific licensing requirements, all HVAC contractors must register with the Washington State Department of Labor & Industries (L&I). The contractor must also obtain a mandatory certification per Section 608 of the Clean Air Act to carry out repairs, service, or maintenance of any equipment that contains refrigerants.

How Much Do You Charge Compared to Other HVAC Contractors in the City of Seattle?

How much HVAC contractors charge in Seattle is dependent on different factors, including the nature and scope of the HVAC project, cost of materials and labor intensity required for the project, and the HVAC contractor's level of experience and qualification. This is why it is best to get bids and estimates from at least three HVAC contractors. This helps you compare prices, pick the most suitable HVAC contractor for your budget, and enables you to filter out any contractor trying to overcharge above the average market price.

Do You Comply with the City of Seattle Building Code for HVAC Work?

The 2018 Seattle Mechanical Code regulates the erection, installation, alteration, repair, relocation, replacement, or maintenance of any heating, ventilating, cooling, and refrigeration systems, including incinerators or other miscellaneous heat-producing appliances in Seattle. The Code also provides the minimum standard to safeguard health, property, and public safety when using HVAC appliances or equipment within the city. This makes it necessary for you to ensure that your intended HVAC contractor is conversant with and understands the city's Mechanical Code. Besides ensuring your HVAC work is safely done, non-compliance with the Code during your project attracts city-imposed sanctions and penalties usually determined by the Seattle Department of Construction and Inspections. In some cases, homeowners may be jointly liable with their contractors for this non-compliance. You can direct all code-related queries to the city's Department of Construction and Inspections at (206) 684-8850.

Will You Get the HVAC Permits as Required by the City of Seattle Code?

The Seattle Mechanical Code requires project owners to obtain a mechanical permit before the installation, alteration, repairs, or replacement of mechanical equipment like heating, venting, and air conditioning. The Seattle Department of Construction and Inspections (SDCI) handles mechanical permit applications and issues mechanical permits upon due review and approval.

Homeowners or their hired HVAC contractors can apply for mechanical permits in the City of Seattle, and such applications can be made via the Seattle Services Portal. Users of this portal must either sign in to an existing account or create a new account before they can utilize the portal. If the permit application is for a Mechanical STFI Permit and Mechanical Plan Review Permit, the applicant must upload all required documents when submitting their application. If the planned project is complex, applicants can request a pre-submittal conference online through the Seattle Services Portal. Once the application has been completed and all necessary documents uploaded, applicants can pay the applicable fees, which are usually calculated based on the HVAC project's value. If the Department approves the permit, the applicant will be notified to print the permits via the portal. Such permits must be displayed at all times in a visible location on the project site. At different stages of an HVAC project, permittees must schedule an inspection. Inspections can either be scheduled online via the Seattle Services Portal or by calling the 24-hour automated inspection request line at (206) 684-8900 or the SDCI's contact customer support at (206) 684-8950.

How to File a Complaint Against a Bad HVAC Contractor in the City of Seattle

Recently, there have been reports of several unscrupulous HVAC contractors going about trying to scam unsuspecting residents in the Seattle City area. For example, in June 2020, a contractor in Washington was ordered to pay back $11,000 to 10 victims after swindling them of thousands of dollars. This scam was done across different counties, including King County. In most cases, this contractor collected money for home remodeling projects but either never started the projects or never finished them. Besides absconding with part or full payments as in this case, other fraudulent techniques utilized by these scammers include:

  • Reluctance to obtain required permits.
  • Pressuring homeowners into making immediate repairs or needlessly changing the specifications of their HVAC systems.
  • Insisting on cash payments.

You can largely avoid being scammed by these fraudsters by taking the following steps:

  • Request for references from your intended HVAC contractor, and be sure to contact several of them to inquire about their work review.
  • Check to see if your intended HVAC contractor is duly licensed by utilizing the Find Trade Licenses by Last Name platform provided by the Seattle Department of Construction & Inspection.
  • Make sure that the contractor is adequately insured.
  • Ensure that all necessary permits are obtained for the project.
  • Get bids and estimates from at least three different HVAC contractors for comparison. This will help to determine if the contractor's charge rates are ridiculously high or low.
  • Ensure you have a written agreement with the contractor. You can engage the services of a solicitor in this regard, especially for large-scale projects.
  • Minimally make cash payments and avoid making full payments upfront. It is much better to make payments with credit cards or checks, as you can document payment histories. Also, only make full payment for the work after it has been completed as agreed.
  • Retain copies of documents related to your projects like contracts, receipts, warranties, and invoices.
