10 Questions to Ask an HVAC Contractor

Choosing the right HVAC contractor to replace or service your home comfort system can be intimidating. That choice is noteworthy because the contractor you hire seriously impacts your HVAC system’s quality, endurance and efficiency for years to come.

To assist you in making an informed decision, research different companies in your area that might be well-suited for the job. Once you create a shortlist of a handful of candidates with adequate experience and positive reviews, contact each one and be prepared to ask about the following top 10 questions to ask an HVAC contractor.

1. Are You Licensed and Insured?

Asking about licensing and insurance ought to be the first question on the list. Hiring a licensed contractor ensures that they satisfy the province and local standards for HVAC companies. Then, insurance safeguards you from liability in case of accidents during the project. A respectable HVAC contractor can show proof of licensing and insurance upon request.

2. What Size HVAC System Do I Need?

HVAC systems are available in many sizes. Installing an oversized or undersized system causes inefficient performance and could reduce the unit’s service life. An experienced contractor can examine your home and figure out the suitable heating and cooling capacity of your new HVAC equipment for the highest level of comfort and longevity.

3. What Brands Do You Carry or Recommend?

Different furnace and air conditioner brands offer products with differing features, efficiency ratings and warranties. It’s best to work with a non-proprietary HVAC contractor that can help you find the optimal fit for your specifications. To get an idea of equipment quality and prices, think about making a list of brands the contractor recommends and why.

4. Do You Offer a Written, Itemized Estimate?

A written quote is better than a verbal quote. When you have an itemized written estimate, you can identify what the contractor charges for each component, including labour, helping you recognize where your money is going. Obtain estimates from several HVAC contractors to help you compare prices and protect you from unanticipated costs.

Remember, prices that seem too good to be true don’t always lead to the savings you are hoping to get. You’ll likely end up with shoddy equipment and inferior customer service, or the company will tack on extra fees to bring the cost up at the last minute.

5. What Kind of Warranty Comes with Your Services?

A one-year labour warranty is the HVAC industry standard. However, you should also question companies about parts and equipment warranties. Some HVAC contractors offer extended warranties and satisfaction guarantees, displaying confidence in their employees and equipment.

6. Do You Offer Maintenance Services?

Scheduled tune-ups are crucial to making the most of your HVAC system’s efficiency and life span. Consider using a contractor that offers tiered memberships to fit your needs and budget. Signing a maintenance agreement with your installer helps bring about solid long-term HVAC performance. It also means you won’t have to restart your search for a skilled contractor the next time you need maintenance or repair work.

7. Will You Pull All Necessary Permits?

Most HVAC work involves permits from local or province authorities. A reliable contractor should handle this process on their own, saving you time and hassle throughout the installation process.

8. What Are My Payment Options?

It’s important to understand how a contractor structures their payment schedule. Always ask if they have financing options or if they will need full payment as soon as the work is complete.

9. How Long Will the Installation Take?

The length of time it will take to install your new system will vary based on the project’s size and complexity. Nevertheless, having a clear timeline is fundamental to cut down on the disruption to your daily routine. Your contractor should provide a reasonable time frame to start and end the project and then follow through on this estimate.

10. How Can I Improve Home Heating and Cooling Efficiency?

Your contractor should certainly be able to suggest ways to maximize energy efficiency by doing a home energy audit. Taking the time to add insulation, replace old windows, seal air leaks and perform other specific actions may help you qualify for a less expensive heating and cooling system. The result is a more affordable up-front investment and lower utility expenses for years to come.
