Frequently Asked Questions
At AC On Time LLC, we understand that choosing the right HVAC solutions is an important decision. Below are some common questions we receive about our services, installation processes, and maintenance options. We hope this information helps you make an informed choice.
How do I know when it's time to replace my HVAC system?
There are several signs to look out for, including inconsistent temperatures throughout your home, unexplained spikes in energy bills, frequent breakdowns that require costly repairs, and systems that are 10-15 years old or older. Older systems tend to be less energy-efficient and may not meet current environmental standards. If you're unsure whether repair or replacement is the best path, we’re happy to provide a detailed inspection and consult with you about the best solution for your needs and budget.
Do you offer emergency HVAC services?
Yes, we understand that heating and cooling issues don’t always happen during regular business hours. That’s why we offer 24/7 emergency repair services to restore your comfort as quickly as possible. Whether it’s the middle of the night or a holiday, our team is ready to diagnose and fix the problem so you can live comfortably again.
How often should I have my HVAC system serviced?
To maintain optimal efficiency and to extend the life of your HVAC system, we strongly recommend scheduling professional maintenance twice a year—once in the spring for your cooling system and once in the fall for your heating system. Routine maintenance includes checking components, cleaning filters, calibrating the thermostat, and identifying potential issues before they become costly repairs.
Are your technicians licensed and insured?
Absolutely! All of our HVAC technicians are fully licensed, insured, and undergo ongoing training to stay up-to-date with the latest industry standards, tools, and techniques. With our team, you can trust that your system will be serviced, repaired, or installed safely and expertly.
