Living in East Tennessee means experiencing the full spectrum of weather. From the heavy, humid heat of a July afternoon in Morristown to the bone-chilling winter nights in Sevierville and the Smoky Mountains, your home’s climate control system works overtime all year round.


Because our weather fluctuates so drastically, a functioning HVAC system is not a luxury—it is an absolute necessity for the safety, health, and comfort of your family or business. When your air conditioner freezes up in the middle of a summer heatwave or your furnace refuses to ignite during a January freeze, you need a dependable team you can trust to restore your comfort immediately.

At Ashton Britt Service Company Inc., we are your trusted local experts for dependable heating, cooling, and HVAC solutions. Proudly serving homes, businesses, and industrial facilities across East Tennessee, we deliver professional repairs, system installations, and energy-efficient comfort solutions designed to keep your property running smoothly year-round.


If you are located in Morristown, Jefferson City, Sevierville, Knoxville, Grainger County, Cocke County, or the surrounding communities, this comprehensive guide will walk you through the essential phases of upgrading, repairing, and maintaining your HVAC system.

Phase 1: Navigating Heating and Cooling Emergencies (24/7 Service)

HVAC systems never seem to break down on a convenient Tuesday morning. They fail on the hottest Saturday of the summer or in the middle of a freezing holiday night.


Recognizing the Need for AC Repair:


  • Your air conditioner is running constantly but your house is still warm and humid.
  • You notice pooling water or ice buildup around the outdoor compressor unit.
  • The system is making loud squealing, grinding, or rattling noises.


Recognizing the Need for Heating Repair:


  • Your furnace is short-cycling (turning on and off rapidly) without adequately heating the space.
  • You smell a strong, persistent odor of gas, burning plastic, or a musty scent.
  • Your energy bills have inexplicably spiked, indicating the system is working twice as hard to produce the same amount of heat.


When these emergencies strike, waiting days for a technician is not an option. Ashton Britt Service Company Inc. provides rapid, 24/7 emergency service to ensure you are never left out in the cold (or the heat).

Phase 2: Professional System Installations & Upgrades

If you are constantly paying for heating repair and AC repair, or if your system is over 10 to 15 years old, pouring more money into fixing it is a losing battle. Older systems are highly inefficient and cost you a premium on your monthly utility bills.


The Upgrade Process: When it is time for a replacement, we don't just swap boxes. Our licensed technicians perform a comprehensive evaluation of your property to recommend the perfect, energy-efficient comfort solution. Modern HVAC systems utilize advanced technology to provide vastly superior, consistent temperature control while using significantly less electricity. We ensure your new system is perfectly sized for your square footage so it doesn't short-cycle or waste energy.

Phase 3: The Power of Preventative Maintenance

The secret to a long-lasting, problem-free HVAC system is routine preventative maintenance. You wouldn't drive a car for years without changing the oil, and your heating and cooling equipment requires the exact same level of care.


Routine maintenance is an investment that pays for itself. During a professional tune-up, our technicians clean dirty coils, tighten electrical connections, check refrigerant levels, and inspect belts and motors. This proactive approach drastically extends the lifespan of your equipment, prevents catastrophic breakdowns during peak seasons, and ensures your system is operating at maximum energy efficiency.

Phase 4: Commercial & Industrial HVAC Solutions

A broken air conditioner at home is uncomfortable; a broken HVAC system at your business costs you money. If your retail store is sweltering, customers will leave. If your industrial facility lacks proper ventilation, productivity and safety suffer.


Ashton Britt Service Company Inc. is not just a residential contractor. We have the heavy-duty expertise, licensing, and equipment required to manage massive commercial and industrial HVAC systems. From complex rooftop unit installations to routine commercial maintenance plans, we keep your business environment safe, comfortable, and operational so you can focus on your bottom line.

Phase 5: The Ashton Britt Advantage

When you invite a contractor into your home or business, you need absolute confidence in their skills, honesty, and professionalism.


Ashton Britt Service Company Inc. has built a reputation across East Tennessee as the name local families and businesses count on for quality workmanship. We pride ourselves on our incredibly fast response times, our team of fully licensed technicians, and our commitment to honest, transparent service.
