I purchased a home that needed a complete remodel which included a new HVAC system. This was the first time I tackled a renovation to this extent and had limited knowledge of what was needed. I spent several weeks looking for local HVAC companies online and found London Heating and Cooling. Mark was one of the first guys I spoke with, he gave me many great tips on what would be best for my new system. After meeting Mark, I interviewed several other HVAC companies to gain knowledge and price shop. Many of the other companies you may have heard about or seen their commercials, they were priced out of my budget or had no real knowledge of redesigning the duct work. Many of the other local companies could only handle switching out the old AC and furnaces in the same location or felt the job was too large for them. The problem with so many other companies I set appointments with would show up late, not at all or never give a bid after walking around the house for an hour. The renovation required relocating a furnace from the basement to the second floor, moving one furnace to the opposite side of the basement, all new AC lines, moving AC units and probably the most important part was adding a complete new duct system. Mark was able to figure out the best way to get air movement throughout the whole house by placing all the returns and vents in the best locations. The design part of the duct work was very complicated, but Mark made it easy for me. Mark had the best recommendations for the new equipment to fit my budget. Mark was early to all appointments and finished the job early. I was always able to get a hold of Mark before during and even after the installation. My recommendation to you is save yourself some time, money, and hassle by calling Mark at London Heating and Cooling. Thanks Mark you did great job I will recommend you to anyone I hear that needs HVAC services. read more

Highly recommend London Heating & Cooling! Mark London took great care of us! We called and Mark came out right away to diagnose the problem. Our furnace was original to the house and over 20 years old. The problem was causing a safety hazard. We received a quote for replacing both furnace and AC unit since they were both same age. He offered us 2 options, American Standard and a cheaper brand. We opted for the American Standard and Mark came out with his apprentice the very next morning and installed everything! His pricing was very good and his customer support was top notch! Thanks for a great experience Mark! read more

I think integrity and honesty is one of the most important attributes I look for when looking for someone to do work in my home. I need to trust what the specialist is telling me and that they will fulfill their promises they give when they are first trying to get your business. Mark London has displayed integrity, honesty and an obvious knowledge of what is needed. He gave us an estimate and kept within the estimate he gave. His workmanship was excellent and he has followed up with us to make sure everything was working correctly. I would highly recommend London Mechanical! read more

London heating is the best! This summer he came out when our 26 year old A/C's went out while I was pregnant and he got our units replaced quickly. This fall we choose to replace our old furnaces as well through him before they went out. Both jobs he did quickly and timely and with very reasonable prices. We also had an issue with our flue pipe cap which he quickly came out to inspect and fix without any issues. I have referred him to family and friends because he does such a great job! We will use him for all of our HVAC needs. read more

During the last heat wave our A/C quit working. We called around and Mark from London Mechanical was at our house 2 hours later with no extra fee for an emergency appointment. He had us up and running within the hour and didn't try to upsell. He was honest and had a very reasonable rate. Of course I checked the price on the replaced part online and what he charged was very fair. We will recommend Mark and use him again when needed. read more

I called London Heating and Cooling on a Saturday late afternoon since my air was not working properly and it was over 100 degrees with the heat index. My husband has such significant health issues so we needed someone immediately. He came over within 15 minutes and left his son's graduation party to come and fix our problem. Which he did,! I would not use anyone else. Such a great guy and great work ethics. read more

I contacted Mark after getting a ridiculous quote from another company to repair a refrigerant leak, and recharge our A/C system. The others thought that I would pay over $2500 for this small repair. Mark did the work for us in an hour or so, and charged $2000 less than the other quote! The a/c is working great! Call London for YOUR needs! Harry read more

Mark was quick to respond. Recommended a great system and installed it quickly. Much quicker than I expected.

Thank you London Heating and Cooling!!! read more

Fantastic!! They took out and actually removed our old boiler for us to put in forced heat and also replaced our air conditioner with a brand new unit.
