    Install or replace heating systems: Replacement; Gas system

    Cozy World did a great job installing my AC, furnace, and tankless water heater. Fred was great to work with, and Saeid did an amazing job installing everything. Thank you! I’ll definitely use these guys again if I need any more work done. Cheers!

    Repair or maintain airconditioning: Centralized, Not sure; 1 unit

    I found Cozy World on Homestars to service my air conditioner several years ago and was extremely pleased. Recently, when my outdoor air conditioning unit stopped working on a very hot and humid Sunday, I leveraged Homestars to contact Cozy World without any hesitation. Ted was extremely responsive to my inquiry and texted me directly. He connected me to Cecilia at the office and she immediately booked an appointment. Ramin came to our house on time (& provided a courtesy call 30 mins prior to arriving) and was able to diagnose and fix the issue in the outdoor unit after completing a thorough check. He also checked our indoor unit to ensure that there no issues and confirmed the entire AC was in good working condition. During the summer heat in which having a working AC unit was critical, dealing with everyone at Cozy World was truly a pleasant &stress-free experience. Thank you so much and keep up the amazing work keeping people cool this summer!

    Install Gas Furnace / Forced Air Heating System

    The service from Cozy World was excellent. The installers were punctual and professional, and left our furnace room cleaner and tidier than it was when they arrived! In addition to installing a new furnace, they also replaced the moldy plastic drain hose from the attached humidifier and cleaned the area around the floor drain without being asked, which we appreciated. Our new furnace is much quieter and more efficient than the old one, and we're very happy with it so far.

    Furnace Replacement

    We contacted Cozy World to check on our furnace as it started making noises and we were afraid that it was going to shut down right in the middle of winter. After deciding to replace our furnace, Dianna was able to book us in for the following week (early December). The timing was perfect as our furnace motor died that weekend. The team was professional, knowledgeable, and pleasant. The appointment booking was seamless. We were updated every step of the way. Our installer, Massoud, was very helpful and knowledgeable. He and his partner left the basement clean, and the installation was quick and efficient. Overall, we were very satisfied with the service received. Once installation was complete, Dianna forwarded the rebate submission and promptly provided us with the warranty information. We'll be happy to use Cozy World again when we are ready to get a heat pump/replace the AC.

    Maintenance Check and will be a repeat customer

    The company was great to deal with from start to finish. Email communication with Cecilia was prompt and the service technician was on time. He explained my issues with my heating system. I was really happy with the results. If any issues arise, I will contact Cozy World again.

    Will continue to use Cozy World Inc., Fantastic crew

    We just worked with Cozy World Inc. for the second time to install our Tankless Water Heater and I can't recommend these guys enough. Our installation team led by Saeed was absolutely fantastic - in fact, he remembered he had been to our home 3 years earlier to install our new furnace! Not only was he incredibly detailed, helpful and kind to work with, but he gave us tips for how to extend the lifetime of our AC unit as well. We will continue to rely on Cozy World and I can't recommend them enough. Thanks Saeed and team

    Best HVAC company, period

    I started looking for reputable HVAC vendors when my 15 year old Lennox Elite furnace started to exhibit intermittent blower issues, and my Lennox AC of the same vintage was leaking refrigerant. I interviewed a handful of them and Cozy World came out on the top of my list. Firstly, they are an authorized Premier Lennox Dealer. Do your homework because many companies aren't authorized! They have been around for over 30 years, unlike my original installer who is now MIA and unreachable. I needed a company I can find if I run into any issues down the road. And somehow they are also able to provide massive discounts. I got an Elite Furnace + Elite AC for almost similar price as some junk builder/entry models from another company! However, price wasn't the biggest factor for me. What sealed the deal was the knowledge that Boris was able to impart during the quotation process. He explained very clearly the differences between the Lennox lineups and answered all my questions no matter how stupid they were. He never tries to upsell. Heck, I upsold myself by reading stuff on reddit. He was also the only one offering to install 5" filters which would increase the lifespan of the system due to better airflow. This is real guys. Look up "Project Farm furnace filter" on Youtube. Furthermore, he offered an original Lennox Aluminum coil from the get-go, and not some copper/alu junk from Aspen or ADP that leaks in a few years. All this was backed by a 3 year labor warranty which was better than some offering only 1 or 2. Then came installation day, and the two Persian giants Saeed and his friend (forgot his name) arrived delivering equipment that were brand new in box. They spent an entire day meticulously installing the new Elite furnace and AC. You can tell the amount of experience they have when you watch them work. They handle sheet metal like those chefs in the food truck. I saw them carefully leveling each equipment, clean out the duck work (due to humidifier filter that was never replaced.. my fault), connecting the system to my Ecobee, and helped me make my existing Honeywell humidifier work like new! I also liked how to reused the outside patio stone from the previous AC to raise the new furnace from the ground. Lastly, they do a good job at cleaning up the space after they are done. It's these little touches that mean all the difference. Unfortunately, a day after the install, I noticed a high pitch whine from the new variable motor furnace. When AC is on, it's very quiet but when heat is on, the high pitch noise gave me a headache. I raised my concern to Cozy World and Cecilia got back to me right away to relay the question to the installer. Saeed then called me and told me that it is likely a defect with the exhaust fan. Cozy World then ordered the part (under warranty) and scheduled a technician Ramin to install it. Once Ramin swapped out the exhaust fan with a new one, the entire system became whisper quiet no matter what mode it's in. Truly night and day difference. It is nice to see a company that stands behind their warranty and doesn't ignore calls/emails when issues arise. I understand now why they have the "Award Winning" stamp on Lennox's website. All in all, Cozy World provided me the best of everything from pricing, to equipment, to installation and to service. I will definitely be recommending them to all my friends and family!

    Cozy World contractor did a quick look at furnace room and determined issue was with outside AC unit. He even had the part required to completed the repair. Total time to repair was less than an hour and cost was $316.40 tax-in. Contractor was very courteous and efficient. Would highly recommend this business.
