AC repairs

AC repairsHVAC contractors in Knoxville TN are qualified to handle many types of ac repairs and maintenance. There are some tasks you can do yourself, such as de-icing the air conditioners and cleaning the condenser coils. Because your HVAC unit is complex, you may need the expertise of an HVAC contractor for other AC repairs.

Top AC repairs that should be left to the professionals.

Electric HVAC Repairs

High voltages and currents required for HVAC systems to work can cause serious health problems and death. This is especially true if homeowners are not skilled enough to fix electrical problems themselves. Not only will you put your family and loved ones at risk, but it could also cause insurance to be voided.

This could result in bigger problems that require more skilled repair. The skills and knowledge required to repair shorts in wiring and fix broken cables and other issues should be left to AC repair professionals.

Changing Refrigerant

According to the Environmental Protection Agency (EPA), about three-quarters HVAC systems don’t have enough refrigerant. Low fluid is the leading reason that some HVAC units blow warm air. Low fluency is not something you can do yourself. Freon is classified as a hazardous substance and can only be handled by licensed HVAC contractors.

A Knoxville-trained HVAC contractor should inspect your unit for potential dangers or damage on a regular basis. Every fall and spring, an HVAC contractor will visit your home to inspect, clean, tighten up, inspect, lubricate, and adjust the internal components of the system. This can help to prevent small problems from growing into bigger ones. A comprehensive review will be performed by your HVAC contractor. This will include tasks such as inspecting the ductwork and air quality as well as cleaning up any units that are found outside.

DIY HVAC repairs can seem like a great way to save money. This is why many homeowners opt for this option. You could end up spending more on the system over the long term if you do not have the experience with air conditioning units.

If you attempt to repair an HVAC unit yourself, the warranty may be voided. A system worth thousands of dollars is too valuable to be compromised. Safety is the next thing. As with all electrical devices, an electric shock can occur if you don’t know what you are touching. An HVAC system can deliver up to 240 volts of electricity, which can cause death. Don’t put your life at risk. This task should be left to the professionals.

Common questions asked about AC repairs

Most HVAC professionals recommend having your AC unit serviced once a year, ideally before the cooling season begins. Regular servicing can extend the life of your unit and keep it running efficiently.

3. Why is my AC unit leaking water?
Water leakage could be due to a clogged drain line, a rusty drain pan, or a frozen evaporator coil. It could also occur if the unit was improperly installed. It’s best to have a professional assess the issue.

4. How long should an AC unit last?
On average, a well-maintained AC unit can last 10 to 15 years. However, this can vary depending on the specific model and how well it has been taken care of over the years.

5. What is the ideal temperature setting for my AC?
The ideal temperature setting depends on personal comfort, but generally, a setting between 72 to 78 degrees Fahrenheit (22 to 25 degrees Celsius) is energy-efficient and comfortable for most people.

6. Why is my AC making a strange noise?
Strange noises could indicate various issues, such as a loose belt, a failing motor, a refrigerant leak, or debris in the unit. If your AC is making unusual noises, it’s best to turn it off and call an HVAC contractor in Knoxville TN to avoid further damage.

7. Can I perform any AC maintenance tasks myself?
Yes, you can and should perform certain maintenance tasks, such as regularly changing or cleaning your AC filters, keeping the area around your outdoor unit clear of debris, and making sure your indoor vents aren’t blocked. More complex tasks should be left to professionals.
