Yes. Our technicians service and repair all brands and makes of heating and cooling equipment, whether or not we installed it, with access to repair parts from all manufacturers. When it's time for new equipment, we'll walk you through the [brands we carry](https://lancasterheatingandcooling.ca/products/brands/) and help you choose the right system for your home or business. ### Are your technicians Lancaster employees or subcontractors? Every technician who comes to your door is a licensed, factory-trained Lancaster employee, never a subcontractor. That means the person diagnosing your system works for us, follows our standards and is accountable to us, and you know exactly who to call if you have a question after the visit. ### How does your pricing work? For repairs, we use upfront, flat-rate pricing: our technician explains what failed and your options, and gives you the price before any work starts. For new equipment, we visit your home, assess your needs and give you a free, no-obligation written quote. You decide with the full picture in front of you. ### Do you charge for a quote on a new system? No. Quotes for new furnaces, air conditioners, heat pumps and other installations are free and no-obligation. We look at your home, your current system and your comfort goals, size the equipment properly, and give you an itemized quote with options. [Request a quote](https://lancasterheatingandcooling.ca/quote/) to book a visit. ### What areas do you serve? Our main office is on the Hamilton Mountain, and Hamilton and Niagara are our focus. We also serve communities in Halton, Haldimand County, Brant, Waterloo Region, Wellington and Mississauga, including Burlington, Oakville, Caledonia, Brantford, Cambridge and Guelph. See the full list on our [service areas](https://lancasterheatingandcooling.ca/service-areas/) page, or [contact us](https://lancasterheatingandcooling.ca/contact/) to check your address. ### What are your hours? Our office is open Monday to Friday, 8:00 a.m. to 4:30 p.m. Outside those hours, our emergency service runs 24 hours a day, so you can reach a technician at night, on weekends and on holidays when your heat or cooling fails. See [emergency HVAC repair](https://lancasterheatingandcooling.ca/emergency/) or [contact us](https://lancasterheatingandcooling.ca/contact/) to book regular service. ### Is Lancaster licensed to do gas and HVAC work? Yes. Lancaster Heating and Cooling is a TSSA registered contractor, and our technicians are licensed for the work they do, including gas work, which in Ontario must be done by certified gas technicians. We've served Hamilton since 1955 and are part of Lancaster Group, which also runs its own sheet metal fabrication shop. ### Can I finance a new heating or cooling system? Yes, for homes. We offer financing through Financeit, so you can spread the cost of a new furnace, air conditioner, heat pump or water heater over monthly payments instead of paying all at once. See [financing](https://lancasterheatingandcooling.ca/financing/) for details, or ask about it when we prepare your quote. ### Can you help me apply for HVAC rebates? Yes. We're a participating contractor in Ontario's Home Renovation Savings Program, so we can submit heat pump rebate applications for our customers. Rebate programs change often and have their own eligibility rules, so check our [rebates guide](https://lancasterheatingandcooling.ca/rebates/) and we'll confirm what applies to your home when we quote. ### Should I repair my old system or replace it? It depends on the equipment's age, condition, repair history and efficiency. A single repair on a sound system usually makes sense; frequent breakdowns on an older system often don't. Our technician will give you an honest assessment and the upfront cost of the repair, so you can compare it with a free quote for [new equipment](https://lancasterheatingandcooling.ca/heating/furnace-replacement/). ## Customer reviews > "WOW-I’m impressed with the quality and speed of work your team performed the last 2 days. Each and everyone one of them were professional, kind and knowledgeable and handled a few hiccups we had by providing options/solutions and not letting it block progress. Having a team that handles all the electrical, plumbing, gas, and general construction work with drilling and mounting made this such a seamless experience, and of course that all started with the information/quote/sales process. Working with Cassandra was fantastic. The transformation of our heating, cooling, air quality, humidity and hot water systems look and work amazingly! I look forward to working with Lancaster for our HVAC maintenance needs going forward and will be happy to refer family/friends as well." — Darryl Chandler, Google, May 2025 --- **Lancaster Heating and Cooling** — HVAC contractor serving Hamilton, Niagara and surrounding areas since 1955.
