Absolutely wonderful service from start to finish. Showed up on time, were professional, and the difference in our home's air quality is noticeable. My daughter's allergies have already improved!
Had them clean my dryer vent after I noticed clothes taking forever to dry. They found a massive lint blockage that was a fire hazard. Honest pricing, fast service, and probably saved my house.
We use 1st Global for our office building's quarterly air duct maintenance. Always reliable, professional, and the team is great with our staff. Highly recommend for any commercial property.
Best decision I've made for my home in years. They were thorough, courteous, and showed me before/after photos of every duct. Highly recommend!
We just bought our first home and 1st Global was recommended by our realtor. So glad we used them — found tons of debris from previous owners and now the air feels so much fresher.
Mor and his team were incredible. Fair pricing, excellent communication, and they cleaned up perfectly afterward. Will definitely call them again next year.
