- adam lovell1.0We wrote a review here as we got an invoice for a service that we did not ask for, got a response to call and ask to speak with the manager, so we did, no manager is available to take the phone and call in 3 days… guy said managers are busy while in reality manager is hiding behind employees, this shows the type of leaders this company has, still waiting for an answer. Definitely not using their services and not recommending at all! This is not the first instance we have used them a few times and this unorganization has happened on the last 3 times they have come out. Not sure what happened to themSeptember 2026Google

About Guest Plumbing & HVAC
Guest Plumbing & HVAC is based at 50 Bittern Street, Unit 8, in Ancaster, which is part of the City of Hamilton, and it also runs an office in Toronto. Google shows 503 reviews at a 4.8 average for the Ancaster location, read September 24, 2026, and lists it as open 24 hours.
The company describes itself as a family living in the community and says its focus is the design and installation of long-lasting systems for new, custom and renovated homes and commercial spaces, working directly with builders and homeowners. It also takes regular service calls. The plumbing side covers residential plumbing, water heaters and water heater maintenance, water treatment systems, backflow services and commercial plumbing, and its photos show tankless water heaters, kitchens and bathrooms. The heating and cooling side covers furnaces, boilers, heat pumps, air conditioning, maintenance packages, indoor air quality and duct cleaning. Guest offers 24/7 emergency service and financing.
On recognition, the website says Guest received a 2016 Young Entrepreneur of the Year award, and it mentions the 40 Under Forty and Outstanding Business Achievement awards. It is a member of the Hamilton Chamber of Commerce and the West End Home Builders' Association.
Reviews describe a well-organized team. Nicole had a tankless water heater installed and named Tayler on the phone, Tyler directing the job, and Ben and Farhatt, who worked all day, cleaned up and gave a walkthrough of the new system. Erik had a built-in barbecue, fire table and pool heater connected and said Farhaat reviewed the natural gas demand before starting. Robert said Ashley replaced a hard-to-reach water shutoff valve quickly, and Monika, a repeat customer, said Ashley swapped old faucets fast. Nikola said Joey diagnosed and fixed a problem at a shop.
The website does not publish warranty terms, license numbers or an email address.
Guest suits a Hamilton or Ancaster homeowner planning a tankless water heater, a gas appliance hookup or plumbing for a renovation or new build, and anyone who wants plumbing and HVAC from one company. It suits less well someone who wants a small, owner-only shop. Ask for warranty terms, confirm the Ontario certificate of qualification and TSSA registration for gas work, and check who pulls the City of Hamilton permit.
