    LG over promises and does not deliver. LG installed a Bladex heat pump and it has never worked right. It stops working periodically - 1 day, 2 days, 1 week, 1 month was the longest. I have been asking them to replace as it has been serviced many times and it still stops working. We were not able to get the government loan as they installed prior to approval. Maybe a class action suit with so many promises and issues with their products. They have an ad about Reliance on Facebook but they seem to be worse. Please review carefully before purchasing from LG. And note they will want a deposit and place a hold on your credit card before they provide service.

    Poolcraft Delivered.....From start to finish, the process was incredible!!. Believe it or not the planning process started years in advance as our backyard had a septic system that we needed to deal with first, before we could get into the pool planning with Poolcraft. The team at Poolcraft was patient while we dealt with the septic and once that was out of the way, the official planning began. From the sales team, design team, building team and landscaping team, everything about process was informative, very trustworthy and we felt incredible thankful for the team we had to bring our backyard dreams come to life. Thank you Poolcraft, thank you!!!

    A toilet in our house came away from the floor in a way that broke the flange it was bolted to. I called MT Drains because they had done a fine repair job in our kitchen a few months earlier. Viktoriya in the office was very friendly & helpful in getting us a cost estimate in a timely fashion and setting up an appointment to fix the problem that fit our schedules. We received email confirmation and reminder of the appointment, and a text confirmation on the morning of the appointment itself. The technician, Amir, arrived a few minutes before the start of the window for the appointment, which I always appreciate a lot! He was friendly, polite and professional. He assessed the repair requirements, confirmed the estimate, and completed the job in a timely manner. Amir also cleaned up everything and even took the garbage away with him. Viktoriya followed up shortly thereafter by phone to check that we were pleased with the job, and then sent the invoice to me for the agreed amount. She also confirmed that they received our payment right away. Ive used MT Drains services for plumbing issues before and will happily use them again!

    Heating & Air Conditioning COOLING At Belyea Bros. we install and service a range of air conditioning systems including forced air (central) air conditioning, ductless split air conditioners, and our custom designed Attic Pak and SpacePak systems. Due to our background as a hot water heating specialists we are experts at planning and executing cooling solutions for houses without ductwork. HEATING At Belyea Bros. Limited we hold the first heating license issued in Toronto. As a result, we have the experience to claim, “there is nothing about heating we don’t know”. We are experts in hot water, radiant in-floor, snow melt systems and forced air heating. Over a number of years we have carefully selected the products that we recommend to our customers. We sell only manufacturers that have a proven track record of quality and service so that we can offer you the best support possible. All the manufacturers we work with have parts centers or distributors within the GTA meaning we have access to a local support network. We offer only reliable premium equipment. HOT WATER TANKS Water heater rentals are a great solution for many homeowners who have a short-to-medium time frame in their house, own a tenanted property, are looking for a peace-of-mind solution to address their domestic hot water needs, or simply wish to have a clear idea of their monthly house budget over the long term without the worry of heater repairs. Many consumers are confused by which company they actually rent their water heater from, thinking that because the charge appears on their gas bill that they rent from “gas-company”. In fact, most customers in Toronto rent their heaters from Centrica PLC, an international energy services company based in the United Kingdom, which operates in Canada under the brand name Direct Energy™. Although they bill on the gas bill, they are not, in any way, affiliated with your gas utility. Belyea Bros. has a wide range of hot water tank solutions for your family’s needs. We have an excellent rental program providing a comparable rate and great reliable products. We provide a fix rate increase, unlike the other guys who may raise your billing at anytime. TANKLESS HOT WATER Tankless hot water heaters are common in Europe and Japan. They can supply an endless supply of hot water, with greater energy savings than conventional tanks. They are, however, limited in the amount of hot water that can be produced at one time and the upfront costs are higher. ELECTRICAL SERVICE Belyea Bros. Electrical specializes in helping home and business owners in the older neighborhoods of Toronto. We provide electrical service, repair and installation whether it’s diagnosing and fixing a broken outlet, or re-wiring your whole home, Belyea Bros. Electrical is here to help.
