SERVING AREAS OF BRISTOL, JOHNSON CITY, AND KINGSPORT TN

One of the most frustrating things as a home or business owner is turning on your air conditioner and getting hot air. In many cases, this happens on the hottest summer days or another inconvenient time when you need cool air the most. Our Tri-Cities HVAC experts at Thompson Electrical Service understand how crucial air conditioning is to maintain comfort in homes and businesses, especially for those who are elderly or have medical conditions. Therefore, we share five reasons your AC is blowing hot air so that you can pinpoint the cause and contact our office to schedule an appointment for repairs.

1. Incorrect Thermostat Setting

One simple cause for your AC unit blowing hot air is the setting on your thermostat. The first step in solving the hot air puzzle is to check the thermostat to ensure you changed it to “Cool” mode instead of “Heat” mode. Additionally, the fan setting should stay in “Auto” mode for the most efficiency. Once you check the above settings, double-check the temperature setting too. If everything checks out, there could be a problem with your thermostat sensor and requires the assistance of our Kingsport HVAC technicians to repair or replace the thermostat.

2. Refrigerant Leak

Refrigerant is the chemical compound inside your HVAC unit responsible for cooling the air by absorbing environmental heat. Unfortunately, your system can fail to cool air even if there is a small leak. Additionally, low levels of refrigerant could also contribute to warm air conditions, especially on the hottest days of the summer. Since the refrigerant is located inside your HVAC unit, it requires an experienced HVAC technician in Bristol to test and fix refrigerant problems.

Below are a few signs that your HVAC system might have a refrigerant leak:

• The outdoor unit is frozen or has ice accumulation
• Bubbling or hissing from the air conditioning unit
• Warm air during the day and cold air at night

3. Leaky, Damaged, or Disconnected Air Ducts

The air ducts in your home or business can significantly impact the quality and coolness of the air passing through them. Unfortunately, that can mean a reduced cool airflow due to a loose-fitting seal, damage due to pests or animals, or a disconnection from an air vent or another duct. Any of these three conditions can cause warm air to enter your home or business. Therefore, conduct a visual inspection of your home’s or business’s ductwork to determine if repairs are necessary. In some cases, a visual inspection is not possible. That’s when you contact a professional HVAC company in Johnson City to conduct the inspection and offer solutions to correct the problem.

4. Dirty Condenser

Regular HVAC maintenance can keep your system running at peak efficiency and reduce potential breakdown risks on the hottest day of the year. During HVAC maintenance appointments, our technicians ensure the condenser is free of dirt and debris. Failing to properly care for the condenser can cause dirt and debris build-up that can prevent your unit from working properly to cool your home or business. Therefore, contact our Tri-Cities air conditioning experts for a maintenance appointment to keep your system running smooth all summer long.

5. Electrical Issues

Electrical HVAC issues for a home or business owner can cause damage to your investment and may require significant expenses for repairs. Although your indoor unit may still run, it will merely blow out warm air from the outdoors. In this case, check the fuse or circuit breaker to ensure they work properly. If the problem continues, seek the assistance of our Kingsport air conditioning pros to determine the cause and a solution.
