★★★★★4.8(2,323 reviews)
94Score

Fix-it 24/7 Air Conditioning, Plumbing & Heating boasts an impressive 4.8 rating from 2,323 reviews. Customers appreciate their comprehensive services that include HVAC repair and plumbing. Their 24/7 availability is a significant plus for emergencies. Still, some reviews mention longer wait times during peak hours, so plan accordingly.

Most of what reviewers hire it for is emergency HVAC and plumbing services. It serves North Charleston, SC, with $100 to $300 pricing, and the honest trade-offs are longer wait times during peak hours and can be more expensive for urgent calls.
