FAQs
How do I know my heating system needs repair?
Common warning signs include uneven room temperatures, strange noises or odors, frequent cycling, higher-than-normal energy bills, or a system that won’t turn on at all. In Charleston’s damp coastal climate, corrosion and salt air can also trigger premature wear on components. If you notice any of these issues, schedule a diagnostic visit right away to prevent a complete breakdown and additional damage.
What types of heating systems do you service in Charleston?
Cozy Comfort repairs all major residential and light-commercial heating equipment: gas and electric furnaces, heat pumps, dual-fuel hybrids, ductless mini-splits, packaged rooftop units, and hydronic or boiler systems. Our technicians are factory-trained on leading brands such as Trane, Lennox, Carrier, Rheem, Goodman, Mitsubishi, and Daikin, so you can count on us for expert service no matter what you own.
How quickly can Cozy Comfort respond to emergency heat repair calls?
We offer true 24/7 emergency service across the Charleston metro area—including Mount Pleasant, North Charleston, Summerville, and the surrounding islands. Calls received before 10 p.m. usually see a technician on-site within 2–3 hours; late-night requests are handled first thing the next morning unless the situation is hazardous. Our service trucks are fully stocked, allowing us to finish most repairs on the first visit.
Are your technicians licensed, insured, and background-checked?
Yes. Every Cozy Comfort technician holds a South Carolina Mechanical Contractor’s license (HVAC), undergoes annual continuing-education courses, and carries full liability and workers’ compensation insurance. We also perform nationwide background checks and random drug testing, so you can feel safe and confident welcoming our team into your home.
Do you offer any warranties or guarantees on heat repair work?
All repairs come with a 1-year parts and labor warranty. If the same component we replaced fails within 12 months, we’ll fix it at no charge. Additionally, our Straight-Forward Pricing Promise means you approve the total cost before any work begins—no hidden fees, ever. For added peace of mind, ask about our Cozy Comfort Club, which extends repair warranties to 2 years and includes seasonal maintenance visits.
How can I prevent future heating breakdowns?
Regular maintenance is the key. We recommend a professional tune-up every fall, which includes cleaning burners or coils, inspecting electrical connections, checking refrigerant levels, and testing safety controls. Between visits, replace disposable filters monthly, keep outdoor units free of debris, and maintain at least 18 inches of clearance around indoor equipment. Joining our Cozy Comfort Club ensures these tasks are handled automatically and keeps your system running efficiently all winter long.
