Absolute game changer - found my go-to HVAC company!…read more Calling an HVAC service can usually feel pretty intimidating with the fear of being overcharged, but Evans Air Conditioning completely earned my trust. Their speed was unreal. I called them at 9:45 AM, and he was at my front door by 10:00 AM. Within 5 minutes of arriving, he pinpointed the exact issue. The customer service was top-tier, and the pricing was more than fair. They also offer a fantastic preventative maintenance plan that includes bi-annual system clean-outs, discounts on parts if repairs are needed, and zero service fees if you ever need to call them out during the year. It's a huge relief to finally feel like I have an "AC Guy" I can truly rely on. I highly recommend Evans Air Conditioning to anyone who needs system repairs or routine servicing!

I recently purchased an older home in downtown McDonough…read more The HVAC system was old and needed immediate replacement. Two companies looked at my HVAC system, one never called me back and the other did not thoroughly examine the system. I called One Call Heating and Air and they quickly sent Jason for a replacement quote. Jason spent time to take measurements of my crawl space and scrutinized connections and potential problems. Jason discussed the requirements with Mike and they gave me a fair quote which I accepted. The install was smooth, quick and very professional. I highly recommend One Call for all of your HVAC service.

Another Update for Google and Yelp 8/19/26: Technician…read morefinally showed @11:20am on 8/19/26. Tech called and asked how I was doing and my reply was awful and he proceeds to say that's good. Finally fixed but just waiting for the next outage on this terrible service. Reliable should be called NotReliable. My mother's unit stopped about 3 weeks ago and it took a week and my grandsons great great grandmother's unit went out as well and they won't arrive to her for almost two weeks for repairs. Both were purchased through Reliable so pleeeeeeeease BEWARE. They don't deserve ANY star for their services and customer etiquette is non existent. Another Update: August 17, 2026 My AC has completely gone on out me on yesterday with health issues, an elderly parent in their 80's here, and a toddler grandson. Reliable states that I'm in a rural area and although the feel is like 110 degrees outside, my thermostat reads 98 degrees, we have nowhere to go. All representatives I speak to advises that we're suppose to wait from Sunday Morning on August 16, 2026 until Wednesday August 19th from 8am-12pm to actually breathe. It's okay for us to pass away from heat exhaustion in our home but illegal by law if in a vehicle. Ive politely begged to speak to someone higher and was not allowed. I've called 3 times with no real resolution for this dire situation for my elderly parent and toddler grandson. I also work from home. BEWARE, DO NOT get fooled. I was also advised that I'm in a rural area but keep in mind that they sent a technician out to get me to buy this awful service in that same rural area the very next day with no problem whatsoever. If heat exhaustion occurs, I must sue. I pay on time each month and get regular scheduled maintenance in which they recently completed. Update: Received a call from them after the review stating someone will be out to fix the ventilation in the rooms and their insurance will get back with me soon. 1:30pm Worst service I have ever seen. Spoke with someone almost two weeks after my system installation due to the system being put in my home improperly and flooding my floors walls and ceilings and no one has reached out to me to assist with any accommodations other than a restoration service. I have loud dehumidifiers hooked up to increase my electric bill (not on a generator), I work from home so the noise is a problem, no type of compensation for this huge inconvenience to come home to after returning from a trip to see my home like this with children, hardly any air coming through the vents in my children rooms causing it to be extremely hot during the day and night, and no responses via email from the one point of contact I was given 5 days ago. Floors coming up in bedrooms and hall floor with odors of mold and my kids and I have terrible allergies. I have never seen such worst customer etiquette in my life. I thought I would have cool air in every room and to move in to my next renovation project when returning home. My floors just have never been right since the flood to my home.

Best HVAC experience we've had in 30 years…read more Our upstairs unit stopped cooling and we called another local HVAC company out to look at it. Took their tech just 10 minutes to tell us we were low on freon due to a bad coil and we were looking at $3500 to replace. Guy never used a leak detector he just knew the leak was in the coil. I wanted a 2nd opinion before spending that kind of money so I called J&R based on their 5 star Yelp rating and the things people were saying in their reviews. Joe showed up, immediately took the unit apart, and spent over an hour using a leak detector to try to locate the coolant leak. Couldn't find a leak. He ended up leaving the system pressurized with nitrogen over a weekend only to come back on Monday and find no pressure loss. No leak - no bad coil. The issue was the other guys (who've serviced our units for 2 yrs) had left the valve caps loose on the exterior unit. Joe's diligence and honesty saved us a lot of money and earned him a customer for life. Its really rare nowadays to find someone with this kind of ethics. Joe's a likeable guy, explains what he's doing and why, and isn't out there trying to run up the tab on the repair. You sometimes hear companies saying they'll treat you like family. Joe never said that and its not on their website or their marketing material but that's definitely how I felt I was treated - like family.

She was really impressed with them. Not only were they friendly and professional, they even took time to answer my wife's questions and entertain three really curious children. They still get five stars. I will now recommend them when I gets the opportunity.
