Common questions
Everything you need to know before we head out.
Assured Comfort Heat & Air is an owner-operated heating and cooling company in Chattanooga, Tennessee, run by Ray Belvin with 35 years in the trade. We install, replace, repair, and maintain residential and light commercial systems across Chattanooga and a 50-mile radius, and we give second opinions on quotes homeowners have already been handed elsewhere. Below are the questions we field most often — on estimates, financing, payment timing, brands, warranties, scheduling, and how to tell a repair from a replacement.
If your question isn't here, calling is genuinely the fastest way to get it answered. Ray picks up the phone himself during business hours, so you get a straight answer from the person who will be standing in front of your equipment — not a script from a call center.
A Chattanooga homeowner's seasonal checklist
Our summers run hot and humid and our winters swing between mild and hard freezes, so equipment here works both ends of the year. In early spring, change the filter, hose the outdoor coil clean from the inside out with the power off, clear two feet of space around the condenser, and run the cooling for fifteen minutes to catch a weak capacitor before the first ninety-degree week. In early fall, change the filter again, test the heat before you need it, and listen for a delayed ignition or a burning smell that lasts longer than the first few minutes.
Two things homeowners often miss: a clogged condensate drain, which shows up as water around the indoor unit or a system that shuts itself off, and closed supply vents in unused rooms, which raises static pressure and shortens blower life instead of saving money. If you have a heat pump, a thin layer of frost in freezing weather is normal and defrost will clear it — a thick, persistent block of ice is not.
How our pricing stays predictable
Replacement quotes are given in person because sizing depends on the house, not the old label — square footage, insulation, window area, duct condition, and how the rooms actually feel. You get the equipment tier, the warranty terms, and the total price before anything is ordered. Repairs are diagnosed first and priced before work starts, and if the honest answer is that replacement is the better value, we say so and give you both numbers.
There are no trip surcharges inside our service area, no upsell on filters you don't need, and no upfront deposit on most jobs — we finish the work, you approve it, then you pay. Financing, including 0% for up to 18 months with approved credit, is laid out at the same visit so you can compare monthly cost against staying with an aging system.
