It took them just over two days to do the work. They were professional and friendly. The project went pretty smoothly, and our new system is working well so far.
Overall, no complaints at all. They were great at communication, provided a reasonable quote, and the work took as long as they originally forecast. read less - 5/05/2021
They were incredibly accommodating and pleasant to work with. Alekos, Michael, and the entire team were very clear communicators throughout the whole process, did top-quality work, and made a potentially stressful project as stress-free as possible. So happy with having fully-functioning A/C now. I cannot recommend them highly enough!! read less - 10/18/2020

They were clean and respectful of our house, indoors and out, even considering the heavy rains that were pouring down throughout the install (furnace closet is located outside!). Ductwork and all of the hardware is all neat and tidy in our cramped little closet. We got a complete rundown of our new Nest thermostat explaining the features and how to best use it with our lifestyle/needs.
I'm a DIY type of guy for most projects, but, I'm very glad I made the choice to go with these guys for this task! read less - 11/30/2018
Before we needed any actual service, we'd connected with them for a consultation on a furnace question. Even though we weren't getting any work done with them at the time, Eric was super helpful and totally non-pressurey in letting us know what our options were.
A short while later when our aging water heater kicked the bucket, we turned to Ariston immediately. We had them replace it with a tankless model and they did an awesome job and were so lovely to work with.
Before, during, and after the water heater replacement, Eric was a constant source of support and he kept us informed every step of the way. When another contractor we were working with at the same time was cutting corners and treating us like crap, Ariston went above and beyond to help us get an adjacent issue related to our gas line taken care of. Eric also handled all of the City of Berkeley's many hoops with grace, patience, flexibility, and a sense of humor. We were actually sad when our project ended since we wouldn't be able to talk to Eric anymore because he's such an awesome dude!
Owning a home is often a pain in the neck: Things break and need fixing all the time. Many if not most contractors are total sheisters, ripping you off and making you feel like crap every step of the way. But not, Ariston -- they are the complete opposite -- a shining light of professionalism, expertise, and happiness. 5 stars isn't enough. They really deserve 10. read less - 7/22/2018
Alekos, the owner, did the installation himself. He is a friendly, personable young man. The work was completed pretty much in a day with a return visit for the city inspection. His price was very reasonable.
Highly recommend. read less - 3/30/2018
Eric went over board to accommodate us with all our needs considering that everything was on a last min call.

FAQ for AC Repair
There can be several reasons why your AC unit is not cooling as it should. It could be due to a refrigerant leak, a malfunctioning compressor, clogged air filters, or a faulty thermostat. Our skilled technicians at Ariston Heating and Cooling can diagnose the issue accurately and provide the necessary AC repair to restore your unit's cooling performance.
Regular maintenance is essential to keep your AC unit in optimal condition and prevent unexpected breakdowns. It is generally recommended to schedule professional AC maintenance at least once a year. However, if your AC unit is older or used extensively, more frequent maintenance checks may be necessary. Our experts can assess your specific needs and provide a maintenance plan tailored to your system.
Keep an eye out for the following signs that may indicate your AC unit requires repair:
- Insufficient cooling or uneven temperature distribution
- Strange noises, such as grinding or rattling
- Foul odors emitted from the unit
- Frequent cycling or short cycling
- Leaking or pooling water around the unit
- High humidity levels indoors If you notice any of these issues, it's advisable to contact Ariston now to assess and address the problem promptly.
While some minor issues can be resolved by homeowners, it's important to exercise caution when attempting AC troubleshooting. Simple tasks like checking the thermostat settings, replacing air filters, or ensuring the circuit breaker is not tripped can be done by homeowners. However, more complex tasks involving electrical components or refrigerant handling should be left to trained professionals. Attempting repairs without proper knowledge can worsen the problem or even pose safety risks.
The duration of an AC repair service depends on the complexity of the issue and the specific circumstances. Some repairs can be completed within a couple of hours, while others may take longer, especially if specialized parts need to be ordered. Our technicians strive to provide efficient and timely repairs while ensuring the highest quality workmanship. They will provide an estimated timeline during the initial evaluation of your AC unit.
