Frequently Asked Questions (FAQs)


How do I know if my AC needs repair or replacement?

If your system is under 10 years old and the repair cost is less than half the price of a new unit, repair is usually the better choice. If your AC is older than 15 years, requires frequent repairs, or is causing noticeably high energy bills, a replacement installation may be more cost-effective in the long run. A Thelen technician can assess your system and give you an honest recommendation.

How often should I have my air conditioner serviced?

Most manufacturers and HVAC professionals recommend a professional AC tune-up once per year, ideally in the spring before the cooling season begins. Annual maintenance helps catch small issues before they become major repairs and keeps your system running at peak efficiency.

Why is my air conditioner blowing warm air?

Warm air coming from your vents is one of the most common AC complaints we hear. It can be caused by a refrigerant leak, a dirty air filter, a malfunctioning compressor, or issues with the thermostat. In some cases it is a simple fix; in others it may require a more involved repair. Either way, a Thelen technician can pinpoint the problem quickly.

How long does a new AC installation take?

Most standard residential AC installations in St. Michael are completed within a single day. The exact timeline depends on the complexity of your system and whether any ductwork modifications are needed. We will give you a clear timeframe before the job starts so you can plan accordingly.

Do you service all AC brands?

Yes. Our technicians are trained to work on all major residential air conditioning brands, including Carrier, Trane, Lennox, Goodman, Rheem, and many others.
