In Ottawa Canada, Carson did a great job of installing a new toilet as well as taking away the old one. All at a reasonable price. We discussed the type of toilet I wanted, he went out and bought the toilet, he installed the toilet and took away the old one. He was fast and efficient and did a great job at cleaning up afterwards. Great Job Carson! Thank you very much! And thank you to John The Plumber!Posted on Google![]()

I chose to go with John the Plumber because of their reviews online. Originally, they tried pawning off the job a few hours before the scheduled appointment to a sister-company because they had an emergency come up. I decided to move the date to accommodate the scheduling conflict and so I could keep John the Plumber as the provider of the service. Matt (plumber) was great! Very personable, knowledgeable and did a great job identifying the issue and fixing the problem. I will definitely reach out for future plumbing issues.Posted on Google![]()

Uneven temperatures may result from poor airflow, blocked vents, unbalanced dampers, or insufficient insulation. Adjusting airflow or sealing ducts can help.
Spikes are often due to dirty filters, leaking ducts, or a failing component. A furnace tune-up can resolve these issues and improve efficiency.
This could be due to a faulty thermostat, a dirty flame sensor, or worn-out components. Regular maintenance can address these issues.
