**For after hours/emergency service, call (225) 240-8478** Specializing in expert air conditioning, heating, electrical, and plumbing services, AccuTemp offers emergency service for Baton Rouge, New Orleans, the Northshore, and surrounding areas!

"Angi advertises that you’ll get an upfront, transparent price before you ever schedule with a pro. That was not my experience here. This company refused to provide even a ballpark estimate for a standard job — a 50-amp generator plug with an interlock — and instead wanted to charge a $69 “dispatch/diagnostic” fee just to show up. That’s not an upfront price, that’s a sales appointment. Very misleading, and not what Angi promises. I will be taking my business elsewhere."

"Beware of shipping issues with this company. Ordered an ice maker installation kit on 10/10/25. Shipping was due no later than 10/20 according to company and FedEx tracking. FedEx tracking showed the package at their facility for 8 days without moving beginning on 10/15. Called FedEx 3 times. Each time they said they cannot find package and I have to contact shipper. Shipper has to make a claim, they will not mark it as lost. Called Appliance Parts Pros twice. Each time they say FedEx has to mark package lost before they will do anything. They also state they have to wait 14 days from them before doing anything because of their contract with FedEx. I don't care about their contract, I want what was ordered and paid for. Just going in circles with them and FedEX. If they shipped after 14 days it would be 22 days from that point, 32 days from the date of order if they shipped it that day.

"The AC unit quit on Friday night. I left them a message on Saturday. AirMedic called first thing Monday morning and arrived at 8:45AM. He had the needed part on the truck and had the AC up and running in less than an hour. We were so pleased, we had him service both units. The total cost was less than I thought it would be. I would not use anyone but AirMedic in the future."

Heating and Air Conditioning questions, answered by experts

Some of the signs of HVAC issues include rising energy bills, rooms not cooling or heating properly, loud noises when in operation, and signs of condensation. To illustrate, if you’re wondering how to stop condensation on air vents, you’ll need to have your HVAC inspected. 

When faced with HVAC issues, it's best to begin by ensuring the thermostat settings are correct for either heating or cooling. If the system isn't responding, check the thermostat for proper function and power supply. It's also important to examine air filters, as clogged ones can decrease performance. Confirm the power supply to the system by checking the circuit breakers and fuses. If these basic steps fail to resolve the issue, contact an HVAC professional for a more detailed diagnosis and repair.

Dry mode positively impacts indoor air quality by reducing excess moisture, which stops the growth of mold and mildew. By maintaining optimal humidity levels, dry mode creates a less hospitable environment for allergens and airborne pathogens, improving overall air quality. However, it's essential to ensure proper ventilation to prevent stale air accumulation.

You should plan to change your AC unit's filter every one to three months, depending on the manufacturer's recommendations. You should also clean the coils at least once per year, but if you have pets or someone in your household has allergies, you might need to clean them more often. Fortunately, many pros will clean the coils and change the filter for you during an inspection, which you should schedule once or twice per year.

You reset your AC after a power outage by turning off the air conditioner from the thermostat, resetting the circuit breaker, waiting 30 minutes, turning on the AC from the thermostat, and waiting 10 minutes to see the impact. Sometimes, with a power outage, the AC needs time to reset itself, so resetting the circuit breaker alone may not do the trick.
