What is the difference between our Diagnostic, Repair and Maintenance Services?


Diagnostic Service

A diagnostic service call is a visit by our qualified HVAC technician to your home. Our team will examine your equipment, perform tests if necessary, and provide a written explanation of any issues. The diagnostic fee covers the technicians time to go to your home to diagnose any issues. If necessary, we will provide a written quote for any repairs needed. Our diagnostic service does not include any repair services.


Repair Service

Our repair service is where our qualified technician will perform a repair to your HVAC equipment according to the written quote provided. This often involves part replacement. If the part is covered by warranty, the cost of the part will be deducted from the repair total. Please note that after hours repairs will be billed at a higher rate (outside of office hours). We will always provide pricing prior to any work being completed.


Maintenance Service

Scheduled maintenance service is a routine appointment to ensure your equipment is calibrated correctly, clean and running safely. A maintenance call can turn into a service call should something be discovered to be an issue. Please note that maintenance service is only completed on working equipment. If your equipment is not working a diagnostic/repair may be required but often can be performed on site for a discount along with the maintenance service.

Did you know that air conditioner repair services are often used to convince buyers to purchase a new air conditioner in Ottawa when it is not actually needed since a repair is the better option? We unfortunately see this very often; an air conditioner has stopped working and a company promises to come out very quickly to replace it. This often happens with cooling units that are 5-7 years old. It is not a new unit anymore and is having issues. Often these ACs have not been maintained correctly leading to problems. One of the most common reasons that we see these failures is due to a clogged filter restricting airflow and causing the system to work harder than it should. At AirZone, we have a team of directly employed air conditioning repair technicians in Ottawa. We do not sub out our repairs because we want to have control over our team and the advice they give to make sure that everyone at AirZone is providing the best advice possible backed by the proper certifications, insurance, and focus on top notch customer service.

AirZone HVAC Services offers air conditioner repairs for all cooling brands. In the field we come across a ton of broken air conditioners each year. This gives us really good feedback about each manufacturer and shortcomings with different cooling design. We get to know which brands to trust and how to get the most out of each product. As an air conditioner repair company we always compare what is in the best interest of our client; to repair the unit or to replace it. We offer honest and straightforward recommendations and always try to do what’s best for our customer. Our technicians are thoroughly trained to compare repair cost versus the age of the air conditioner while also considering additional factors such as efficiency. For example, a 9 year old air conditioner that needs a 1500 dollar repair is likely not worth it. It would be better for the customer to instead invest in a new more efficient cooling unit which will offer better dependability and provide energy savings! When financed the cooling unit cost per month can actually be less when considering the cost of the repair. On the flip side if the air conditioner is 3 years old and needs a repair we do everything we can to get that unit working the way it should. This includes in depth training of our team in house and directly with the manufacturer, up to date knowledge about new repair parts and procedures, and repair vehicles equipped with commonly needed parts (to repair all brands). Bottom line is that AirZone is the one to call for a broken air conditioner due to our focus on customer service, honest and transparent advice and pricing, and technical expertise. Thank you so much for considering us for your air conditioner repair!
