What People Are Saying
Our commitment to excellence is reflected in the words of our satisfied customers.
Tom H.
"Great service! They were able to get my work done a few days after inquiring, the job went great, good price, great communication and I've already recommended this business to my neighbors."
Asad Bhatti
"Absolutely amazing experience, these guys will take care of all your HVAC needs and will work out a great deal with you. Zach and Robert are great guys to work with! Highly recommended!"
Kate O'Neil
"This is the kind of company you want to have in your arsenal. They are amazing. Zack and Robert are honest guys doing a good day's work. They have integrity and they do what is best for the customer. They charge a fair price and they do an excellent job."
Kristeen Griffin-Grimes
"When our furnace fan stopped working recently, we reached out to several contractors to diagnose the problem. Robert and Zach responded almost immediately, and it became clear that we needed a new furnace. We were very pleased at how quickly they were able to get a new furnace installed - within just a couple of days. Not only that, but they went above and beyond by securing the furnace and ducts to the walls or ceiling, and taping all duct joints, as that had never been done by previous contractors. We can't say enough about how professional and courteous this company is. We highly recommend them for any heating work someone might need."
Sevda S.
"Costco left my range like this and refused to install it, leaving me in tears because I needed to cook for my daughter, who has a special condition and can only eat homemade organic meals. I found this company online out of desperation, without much hope, but Robert went beyond my expectations. I'm not just talking about how skilled he is at his job—he also has a great heart and truly understood my situation. He stayed for almost two hours because the Costco delivery guy had taken some parts with him! Thankfully, Robert found a solution, did a lot of extra work, and didn't even charge for it. I can't express my gratitude enough for what he has done for us. I highly recommend his service 100%! He is amazing, and good people like him need to be appreciated because we need more of them!"
Tim A.
"Amazing install/work done THANK YOU!!! Had a new HVAC system installed. Did my research & they had the best price. Got it installed right away. No surprise costs. What was quoted is exactly what was charged. Super friendly and helpful. As a bonus with my old HVAC they will recycle as much as they can instead of it going in the trash. Will HIGHLY RECOMMEND Greener Cleaner Heating to friends and family."
Kristy J.
"I recently had Greener Cleaner Heating and Air install a gas furnace and new heat pump, clean my dryer vent, and service my gas fireplace--and I couldn't be more impressed!! My fireplace looks brand new, and the heat pump is working flawlessly. The team was professional, punctual, and took the time to explain everything. Highly recommend their services!"
Anthony W.
"These guys are incredibly knowledgeable, friendly, and they make recommendations without any pressure. They did an awesome job providing maintenance on both my central air and mini-split units. Everything is running smoothly now, and I appreciate their attention to detail and honesty."
Drew K.
"I reached out to a number of companies in immediate search of a new heating system. Our previous electric furnace kicked the bucket after 46 years. You might say it had a great run, but it was time. Greener Cleaner Heating & Air responded promptly, assessed our needs, and installed a new system efficiently. Their professionalism and expertise were evident throughout the process."
Faz H.
"This is truly an amazing company! I don't leave reviews partly because I usually forget, but this experience is something I didn't. Robert came down to help take a look at my heater issue and told me exactly what was wrong and how to fix it. He was honest, didn't try to upsell me, and even gave me tips on maintenance. It's rare to find such integrity these days."
Jonathan C.
"Zach (owner) came to provide us an estimate, free of charge, on his day off. He was very thorough and provided us a couple options to move forward with. His professionalism and willingness to go the extra mile were much appreciated."
Stephanie
"Robert provided a same-day quote and scheduled the work for the next day. Zach and Moses expertly installed the furnace, hauling it up three flights with care. They were professional, knowledgeable, and great to work with. Our heat was restored within 24 hours."
Stephanie
"They even added an air purifier which is around 1.5-2x with other companies for a very affordable price. They knew what they were doing and were very careful to make sure we understood what was the problem and what they were going to do to fix it. I would highly recommend them to anyone! Thanks for doing such an awesome job!!!"
C.M. from Renton, WA
"If you want a skilled, reliable, honest, hard-working, and kind repairman that can do electric work, I can honestly recommend 'Greener Cleaner Heating & Cooling LLC'. The great part is they won't take you to the cleaners. Zach came out to fix my GFI outlet and bathroom outlets associated with it. He looked at the breaker box, outlet box, etc., and fixed the problem. Didn't even charge me the diagnostic charge that some of the other electric companies wanted to charge. If I could give 'Greener Cleaner Heating & Cooling' 10 stars or more I would. You are my go-to guy now for electrical. Satisfied customer."
