I recently contacted Superior Plumbing with a request to find and repair a plumbing leak in my bathroom. Following investigation of the source of the leak by their employee Andrew, I was informed by him that the source of the leak was the wax seal under the toilet. He also identified that the toilet was aged and not in good repair and he suggested replacement. He provided a quote of $1,200 + tax for the work necessary to repair a water leak in my bathroom and replace the toilet. This work was done two days later by two installers. The work took approximately 45 minutes. After the work was completed, the installers advised me the toilet flange was also broken and provided me with an estimate of $800 to replace the flange. I did not accept this estimate as I was suspicious of the amount I was a being quoted for this repair. The work that was done that day did not stop the leak. When I contacted Superior Plumbing the next day to advise that the leak had not been fixed, I was told that the plumbers who installed the toilet were not aware that a new wax seal was to be installed and that they would return to install a new wax seal. I was also advised that a new toilet flange would be installed at no cost as a "courtesy" because of the installers error. I fail to see how this is a courtesy when, as I have learned, it is standard in the industry to change the wax ring and replace the flange on the toilet anytime a toilet is removed or replaced. The installers returned two days later and installed a new wax ring and toilet flange. Upon completion of this work the leak was still present. Another investigation by the installers that day found that the leak was coming from a pipe below the toilet, not the toilet itself. He seemed surprised that Andrew had identified the source of the leak as the toilet in the first place. I was then provided with a quote of an additional $650.00 to have the leaking pipe fixed. Given the inaccurate diagnosis, failed repairs and escalating costs I declined the estimate. When the installers left that day they dumped the bucket of drywall they had removed from my ceiling (to find the leaking pipe) onto my front lawn. I had paid $1356.00 to that point and the leak was not fixed. I paid $1356.00 to have a $350.00 toilet installed. Realizing that I had been grossly overcharged I requested a proper invoice including a detailed breakdown of both the parts and associated labour costs for the work done. When this was not forthcoming I contacted the number for the head office and was advised that "Superior Plumbing does not issue that kind of receipt" and that I would not be receiving any further documentation. I went to speak with someone in person at the local office only to find that the address provided on the company website is actually the address of another local business. Superior Plumbing is not located at the address advertised on their website. I looked up Superior Plumbing on the Better Business Bureau (BBB) and it turns out they are not accredited with the BBB. They have a rating of F. The lowest possible rating. I wish I had looked the company up before I hired them to fix my leak. They took advantage of my lack of knowledge about plumbing and my feeling of urgency to get the leak fixed. I would not hire this company ever again and I would actively encourage others to avoid them at all costs.Latest review: - Leopard HVAC ServicesHVAC contractor in Thornhill, Ontario

I was recommended to Irwin Heating from a close friend. He used him (Giancarlo the owner) for several matters including AC replacement and other furnace fixes. The reason why I reached out is I heard he is the consummate professional, super responsive, very knowledgeable and is reasonable in their advice and price. Im so glad I called him in to diagnose our 20 year old furnace which had been acting up. He was so responsive to booking a time to come see the furnace and to give his honest feedback and recommendations. We scheduled in for his crew to come install a few days later and I am extremely IMPRESSED. They know what they are doing and are just very courteous with service and with my concerns that I had and all my questions that I had!! They (especially) the lead installer ALEX was so patient with me and ensured I knew what was going on and that I understood their installation. Thank you we are going to have a warm and safe winter season!Latest review: - Ideal Heating & Air Conditioning LtdHVAC contractor in Thornhill, OntarioRating: 4.7 out of 5Get in touch

If you’re looking for one of the most professional commercial HVAC contractors, you’ve come to the right place. General Knowledge Of The Home When it comes to heating and air conditioning there are a lot of factors that can affect the efficiency of the system. Sure, if the ducts are broken and leaking, you are just spewing out good money, but there are other factors like insulation and location that can affect how your units operates. If your home is not adequately insulated or the unit itself is located in the hottest part of the home it is going to have to work much harder, which will reduce the life of the unit, and cost you more in the long run. Here at Wesolveheat , we make sure that our techs are equipped with this type of knowledge in order tackle and solve your problem in the most effective and efficient ways possible. Proper Heat Load Calculations Before Installation When most HVAC contractors suggest that you install a new unit, they automatically just suggest replacing the unit with the same size unit that you already have. For instance, if you have a 3-ton unit, they will just go ahead and make the assumption that a 3-ton is sufficient for the home. Of course, in most cases it is but if you have made additions or changes to the home, a new heat load calculation needs to be performed. We equip our sales staff with the tools and knowledge to perform a heat load calculation, before even giving you a quote on a new unit. Not only does this ensure that you are going to get the proper sized unit, but it can also give you can estimate of what it will costs annually to heat and cool your home with this new unit.

We moved into a new home with an unsafe wood fireplace. We wanted to convert it to a gas fireplace insert. We reached out to many contractors on HomeStars, but Bobbi was the only one who actually came out to speak to us and give us options. He was attentive, professional, knowledgeable, and his suggestions were spot on. Mohammad, Damon and a third whose name escapes me (sorry) were a fantastic install team. They left the worksite clean. Gave us a walk through of how to work the remote and answered any questions we had.

Installation ─── Providing the optimal combination of energy efficiency and comfort our furnaces and air conditioners will save you more money while also doing their part to help the environment. It doesn’t hurt to consider a furnace with an Annual Fuel Utilization Efficiency, also known as a AFUE rating, and an air conditioner with higher SEER ratings.

Attic Insulation ─── As experts we at A.C.S. agree that the majority of heat loss or gain that takes place in a home is done through its attic. This estimated heat loss can be as high as 45% depending on what type of insulation your attic has. With an alarming potential for heat loss like that it’s easy to see why you need to pay special attention to how your attic is insulated. In winter, when you heat your home that heat rises and your attic insulation is the first line of defense to stop that heat loss and save energy. In summer, hot humid air also penetrates into your attic and makes your home harder to cool. Hot Water Heating ─── After home heating, hot water tanks consume the most energy in your home. Control your home energy costs by choosing a more energy-efficient hot water tank . Owning a new Water Tank helps manage cash flow, and comfort! Get a Smart Solution for Hot Water Heating.

Nothing but good feedback for Mohammed and his team. When the old furnace started to act up, I contacted a few contractors for a replacement quote. Mohammed was very quick to respond, making himself and his team available for the same day replacement (no fun with no heating on a cold December night), offering top notch advise on a suitable furnace choice and presenting a competitive quote. Job was completed to our satisfaction, and a non-critical post-installation glitch was remedied without delay.Latest review: - Laird & Son Heating & Air ConditioningHVAC contractor in Thornhill, OntarioRating: 4.5 out of 5Get in touch

I purchased a wall hot water unit from them. Their explanation of the unit's features and benefits was very helpful and the installation was done perfectly without any issues. I have it serviced yearly and the service people are very professional. I have been completely satisfied with the purchase and the service. They are a little more expensive than some others, but I feel they have earned it.Latest review:
