Best System Maintenance in Saint Louis MO

Great company to work with. I called late at night for a clogged drain and received a quick response. I was extremely satisfied with the service and the price was a great value! Will definitely recommend and use this company again in the future!

He was able to help us out with our bathroom vent.  My husband got stuck & we needed someone that could repair & get the job done. It worked out perfect! Fair price & good quality work!

Sean completed the job same day.  He was thorough, friendly, and reasonably priced.  Definitely recommend him.

Bel-O came through in our time of need.  Our a/c quit so we called them for help.  We've used them for other heating and air system problems before and have always had good experiences.  This time was no different.  They were swamped with service calls all day so they had to help us after hours.  They sent John, who was excellent.  He was pleasant and professional, and he helped us not just by fixing the problem (thankfully just a blown capacitor and not a whole new unit), but also gave some friendly advice on how to make our home more comfortable by changing how we use our thermostat and manage the return air in the basement.

He could've said the unit was shot and I wouldn't have known any better.  How often do you find kind, quality, HONEST service these days?  I'll keep calling Bel-O for our HVAC service needs, and to replace my a/c unit when it does finally quit.

First, let me be clear that I can't review their quality of work for installs or repairs, because I haven't hired them for that.

I needed to replace my AC and furnace, so I sought bids from 6 companies. The Anton's bid experience was different from the other 6, and not for good reasons.

They were the highest price of the 6 bids I got. I don't begrudge a company for asking for a high price if the product/service has the quality to match it. The internet research I did suggested that the product being quoted was actually a budget/mid-tier system, not a premium product.

I also found the bid process to be the least professional out of 6, and it wasn't even close. I made it a point to go down to the basement after each bid to make sure the outside door by my AC/furnace was locked and lights were turned off. When I went downstairs after the Anton's guy left, I found the door unlocked and a metal cover to the unit left on the floor. By contrast, the other 5 locked the door, and nobody else failed to replace the cover.

The high price made it really easy to not choose Anton's, but I feel confident that if the price was comparable to the ones I was seriously considering, I wouldn't have chosen due to the lack of professionalism shown in the bid.

Robbie came out to check why my hot water heater wasn't keeping hot water properly.  He found a bad element and advised that both elements should be replaced at the same time especially since it was probably still under warranty.  Instructed me on contacting the manufacturer to get replacements. I received my replacement parts and Robbie came back out to install the elements.  During both visits Robbie was very courteous and answered all my questions. Thanks AAA and Robbie

Can I give zero stars? Wish I had read the other reviews before having work done by these guys. Stay away indeed! Like the other review, they focused on paperwork more than customer service and tried to sell me monthly plans than get down to business. I needed my A/C fixed and knew what part needed replacing but didn't realize it would cost me hundreds to get it fixed. Part only cost $40. Not to mention they charge by the job not by the hour. Job was very easy, a few screws and plugging in wires and it was done. Don't bother giving these guys your business, forget it!
