Troubleshooting an AC That Won’t Stop Running

Air conditioning repair companies in Nashville are experts at troubleshooting household cooling problems such as machines that won’t stop running. The specific air conditioning repair that will be needed depends on the underlying cause. In some cases, an AC won’t shut off because the relay board, main control board, or temperature control board have failed. All that may be needed to get your AC working again is to replace the failed components.

When you watch this video, you’ll discover that the thermostat might also be to blame. Your air conditioning repair technician can use a multimeter to test whether the thermostat is working when the AC is on a cool setting. This lets the technician determine whether a replacement thermostat will fix the problem.

Should You Turn Your AC Off When You Leave the House?

It is sometimes thought that if the AC is shut off for a few hours, it will use more energy to get the home cooled back down again compared to leaving it running. But actually, AC maintenance experts in Nashville strongly recommend turning off the AC if you’ll be out of the house for more than an hour or two. This is because air conditioners tend to stay more efficient when they are working hard, compared to when they are just maintaining the temperature. This could mean that you won’t need to schedule air conditioning repair services quite as often.

Another compelling reason to turn off the AC is that it will help you keep more money in your pocket. There isn’t much sense to pay to keep a home cool when no one is there. Shutting off the AC can keep your utility bills lower. Plus, reducing your energy consumption is an environmentally responsible thing to do.

Could Your AC Be Heading for a Summertime Meltdown?

During the sweltering dog days of summer, Tennessee residents like to stay close to their air conditioned homes. But it’s frustrating when an air conditioner suddenly fails, even if the AC repair company in Nashville offers emergency service. Getting your unit regularly serviced will help prevent untimely summertime meltdowns. It’s also a smart idea to know the warning signs that an AC repair is needed in between your usual maintenance appointments. AC - Unit

Your home’s temperature is consistently higher than the thermostat.

One warning sign of imminent failure is a significant, consistent gap between the thermostat and the actual temperature. If you find yourself constantly turning the thermostat down farther, but your home isn’t getting any cooler, it’s time to call the air conditioning repair service. Another warning sign is if the temperature in your home fluctuates from room to room.

Your AC unit is making alarming noises.

It’s perfectly normal to hear a low humming noise when the AC is running in the summer. But if you detect unusual noises, you should schedule an air conditioning repair appointment promptly, before the unit completely fails. Sometimes, a difference in the noise may be subtle, such as a different type or volume of humming. In other cases, the noise might be alarming, such as a loud clanking or grinding noise.

Your AC unit is emitting unusual odors.

Has your family been complaining of unusual odors around the house lately? After ruling out the obvious causes, like a garbage can that needs to be emptied, consider taking a whiff of the air near a vent. An AC that has been emitting foul odors is definitely a cause for alarm. It’s possible that the odor is due to accumulated mold and mildew, but it might also indicate that the unit is going to fail soon.

Your electricity bill is much higher than usual.

If there’s something wrong with your AC unit, it may have to work harder to cool your home. You’ll notice the difference when it’s time to pay the electricity bill. Invest in a service appointment with the repair company, and you can look forward to a lower utility bill next month.

How UV Light Could Help Your Family Breathe Cleaner Air

Ultraviolet (UV) light has an incredible range of uses. In 1903, this then-new technology led to a Nobel Prize for the scientist who discovered it could be used to support patients with tuberculosis. More than a century later, it’s being put to good use by HVAC repair companies in Nashville as a way of improving indoor air quality . This technology has been proven so effective at reducing contaminants that many commercial buildings, including hospitals, have been getting HVAC UV lights installed. If you’re dissatisfied with your indoor air quality, it’s time to upgrade your home’s technology. UV - light

Common Concerns with HVAC Systems

The thought of mold and mildew spores, bacteria, and other pathogens floating through your home probably isn’t appealing. And if someone in your family has allergies to mold or a respiratory illness, like asthma, these common household contaminants can be downright dangerous. HVAC systems that circulate pathogens throughout your home are also highly undesirable for family members with weakened immune systems, including seniors and babies. Getting your ductwork cleaned out regularly might not be enough to protect your family.

Benefits of HVAC UV Lights

An HVAC technician can install professional-grade UV lights in your home to effectively kill pathogens before they can circulate throughout your home. These devices cleanse the air of organic matter, which includes mold, mildew, fungi, bacteria, and viruses. When you have a UV light installed, you can look forward to the following benefits:

  • Removal of volatile organic compounds (VOCs)
  • Reduction of unpleasant odors
  • Reduction in cold and flu germs circulating in the air
  • Control of mold and mildew spores

Additionally, UV lights can keep your AC unit running smoothly because they keep the coil cleaner. This could mean reduced electricity bills and less frequent repair visits.

Maintenance Issues to Be Aware Of

To keep your entire system running well, be aware of the maintenance needs of UV lights. They will require routine cleaning and the bulbs will need to be replaced about once per year. Your HVAC technician can easily handle these maintenance tasks for you.
