How we'd handle this for Russellville, KY

A/C diagnosis is gauge work. We hook up high-side and low-side gauges, look at the pressures and the suction-line temperature, and isolate the failure: low refrigerant (leak), bad expansion valve, compressor failure, clogged condenser, blocked airflow across the evaporator. Bunk heater work is similar — read the fault codes, check the fuel delivery, check the combustion-air, check the glow plug. The fix is usually a specific failed component, not the whole heater unit.

Frequently asked

Do you actually work in Russellville, KY, or just nearby?
Russellville is where the shop is at Logan County Court House. Most Russellville jobs are same-day, often inside the hour for emergencies. Call (931) 561-7736 and we'll tell you the real arrival window.
My A/C is blowing warm air. What is it usually?
Three usual suspects in order of frequency: low refrigerant from a small leak, failed compressor clutch, or a stuck expansion valve. Gauge readings tell us which.
How long does an A/C compressor swap take?
Typically 4–6 hours including evacuation, replacement, leak check, and recharge. Some engine layouts make compressor access harder and push that toward 6–8.
My Espar bunk heater is throwing a code. Can you fix it?
Yes — we service Espar D2/D5 and Webasto Air Top units. Most fault codes are glow-plug failure, fuel-delivery issues, or combustion-air blockages. Parts are stocked through the OEM channels.
I'm losing coolant inside the cab — heater core?
Almost certainly. Coolant on the floor mat in front of the passenger seat (or driver, depending on the truck) is heater core leakage. Heater core replacement is a dash-out job on most heavy-duty trucks — a real labor item, 6–10 hours typically.

  • “Brennan was great — absolutely hire this guy. I own a local tree company in Goodlettsville and one of my work trucks broke down at short notice. He was able to get there within a day or two and diagnose it. My turbo went out on one of my vehicles — when I went to the dealership they told me the wait time was forever and the process would include taking the cab off, which wouldn't work well with my current setup. Within one day he was able to replace my turbo and get it running so I could get back in business. The job was really labor-intensive but he made quick work of it and it runs even better than it did before. He's now the main guy I go to.”

  • “We've used Blacktop Mobile Repair twice this month, and both experiences have been nothing short of amazing. They run a top-notch operation, and it really shows in the quality of service and professionalism they provide. Jacob, the service tech, went above and beyond to make sure our truck was taken care of. He even drove out of his way to make sure he had the exact part needed to fix the truck and get us back on the road quickly. That level of dedication and commitment is hard to find. As a trucking company, downtime is costly, and having a team like Brennan and Jacob we can rely on makes all the difference.”

  • “I've used these guys in the past for an air compressor installation. Jacob was great. And recently my alternator quit on the weekend. I called Jacob on a Saturday and he helped me find one that I could pick up myself. Both times Jacob was knowledgeable & fair. A few months later — again on a Saturday — I wasn't even in their area and I called again to get troubleshooting advice. They are very good at diagnosing. Was able to pinpoint the trouble. Thanks again guys!”
