Why Locals Love THA Heating Air & Plumbing

⭐⭐⭐⭐⭐

Oliver from THA did an amazing job! He was able to diagnose and fix our plumbing issue really quickly. He was polite and friendly, and he was able to walk me through what he found and explained the preventive measures we can take to help avoid future issues. I will definitely be using THA again, and would recommend them to anyone who needs quick support.

Oliver was fantastic. The best plumber I’ve ever worked with. He is patient, polite, knowledgeable about many contracting specialties, explains things well, and answers questions. He cleans up after his work better than he found the site. If you want to have this kind of plumber in your contacts to share with your friends and family, Oliver at THA is your guy.

Matthew and his crew went above and beyond to help our family. We have a 10 day old newborn and our property management company (Beyond Property Management) was doing nothing to help us get our broken air conditioning fixed. Matthew stepped in and helped us the day of to get the issue resolved before a warm holiday weekend. I cannot recommend Matthew enough, they were professional, timely and empathetic to our situation. Thank you Matthew and crew for helping our family!

Ishmael and Oliver were very kind helping me fix my garbage disposal. Even took the time to teach me how to troubleshoot in the future! Prompt service and appreciated the main office calling in the morning to confirm everything was still on track.

This was the second time we used THA services THA sent out Oliver Rivers who was the plumber who did the work. Super nice guy, very professional and did excellent work. I watched him preform his tasks, and he was very detailed oriented and didn't cut corners. We are impressed by his expertise and will consider using this company again in the future. Matthew Metanat, the owner of THA is very professional and kind. We asked him for a discount and he agreed to give us a discount on the new water heater that we needed to replace the old one (after 12 years). We purchased the old one from them too and we were happy with it for 12 years.
We were very pleased with the work THA did for us, and can highly recommend this company. We are confident you will receive the same professionalism and workmanship as we did when choosing this company for your Heating and Air Conditioning needs. t experience, I would recommend this company to anyone
