"They were super helpful, they rushed the service. They picked uop the unit at night from the manufacturer. They went out of their way. The replacement units are working well and they were installed properly. I have been trusting their services and they have been working on two of my houses for around 20 years now."

"I was satisfied with the work Jason did for me. We discussed the various items that I wanted to address & the main focus was on the faucet installation on my bathroom sink in the basement. Jason explained why I had to get a new stopper. I was a bit surprised about the total cost of services; but inflation has changed just about everything. I was particularly appreciative of how well he cleaned up after completing the job. That is a major plus for many customers! I would like to request Jason for future jobs."

"Vitt's HVAC service tech was a experienced professional who listened to my concerns regarding my furnance's performance and what I thought the problem might be. He examined the complete unit, determined the cause of the problem and performed the necessary service. He worked quickly and cleaned up the area afterwards. He also was able to tell me how old the unit was because I did not know."

"Excellent service, very fast response to my request for service, picked up laptop, diagnosed issues. Initially thought it was an OS update issue but the hard drive had failed along with other components (including 'CPU). Because other components were involved, a new solid state hard drive was put into a laptop with a working processor - same type CPU as in the failed unit. The laptop was repaired and returned in less than a week. This company picked up and dropped off the laptop (driving from Huntsville, AL (about 60-70 minutes)-- great service in this covid environment. I would recommend this company to my family./friends and will use again."

"Good! Quick and easy. It was like 30 degrees outside, I had a kid in the house, and he was there within the hour to fix it. When he showed up, he didn't charge for a diagnosis or a service call, just parts and labor."

"I am extremely happy with Ballieu Services. The air conditioning quit working on a hot Sunday. They responded to my call immediately and had someone out here in less than an hour. They fixed the problem and charged me a whole lot less than another company that had been here before, saving us quite a bit of money. Two guys came out - both were knowledgable, informative and friendly. They have all of my future business and I would definitely recommend them to a friend."

FAQs for window a/c unit service or relocation projects in O Fallon, MO

If your window air conditioner is relatively new or of high quality, repairing it can restore optimal performance and protect your investment. However, for older units or those with ongoing issues, it might be more cost-effective to replace the unit to ensure long-term efficiency and reliability. Consider the unit's age, the severity of the problem, repair costs versus replacement, and energy efficiency ratings when making your decision. If repairs cost more than half the price of a new unit, replacement is typically the better option.

Window air conditioners last eight to ten years on average. After this time, you may notice decreased efficiency and component wear. Replacing an older unit can improve energy savings and provide updated features like remote controls and better overall performance. With proper maintenance including regular filter cleaning, coil checks, and professional servicing, you can maximize your unit's lifespan.

If your portable AC isn't cooling, it might have a refrigerant leak or a circuit malfunction that's preventing it from working properly. It's best to contact a local air conditioner contractor to inspect and repair the unit. If your AC is older and repairs don't fix the issue, replacing it might be the most effective solution.

Removing a wall-mounted AC costs $55 to $75. Completing the removal yourself at the end of each summer season, being sure to do so according to proper guidelines, keeps you within this cost range. Should you require professional assistance for removal and disposal, if you can't move the unit yourself, expect an added fee of $25 to $50 to the overall cost.
