When you become aware of the signs that an HVAC system needs to be repaired or replaced, it will protect you from damages and costly maintenance down the road. In this circumstance, replacing your heater in the summer and your air conditioner in winter is a wise decision.

If you cannot inspect any underlying issues with your HVAC system, contact our professional for HVAC repair. Our HVAC professionals will advise you on the best course of action for air conditioning repair in Fairfax, VA.

When Should You Repair It?

Replacing small components or fixing minor issues is part of your HVAC system’s repair process. You may need to contact HVAC services for significant repairs, such as a vital element that has ceased operating. It would help if you thought about how old your HVAC system is in such instances.

If it has outlived its useful life, you will need to replace it. If your present system is still under warranty or hasn’t reached the end of its useful life, you can have it repaired for free if the repaired thing is covered by a warranty, rather than paying money or spending some of your savings.

When Should You Replace It?

Persistent Malfunctioning

If you notice that your device is not performing as it should, you may need to consider replacing it. For example, if your AC continues to blow hot air after repair or your ventilation system does not filter dust particles in the air. These issues indicate that your HVAC system needs to be updated.

Freon Technology

If your system uses Freon technology, it means it’s ancient, but it also means it’s less efficient overall. Freons are inefficient in comparison to modern technology. Freon-based systems are inherently inefficient. Freon models also require frequent and costly repairs.

Strange Odors and Noises

Strange odors and noises are almost always a clue that something wrong is happening. It’s possible that your HVAC system has to be replaced. Some issues, especially mechanical components, are beyond AC repair in Fairfax, VA.

The System’s Age

The age of your present system is an obvious indicator. Most HVAC appliances lose their efficiency after 15 years, and some even quit working after ten. You should think about the age of your current HVAC before you consider a replacement or AC repair in Fairfax, VA.

The Total Number of Repairs

Newer systems do not require as many repairs, but as the system ages, its constituents lose efficiency and may need to be replaced. If your current furnace requires hundreds of dollars in repairs, it is advisable to save the money and get a new one.

Irreparable Parts

If your HVAC system has been repaired twice a month, but the problem persists, it is not the HVAC company’s fault that you called but because of the system’s irreparable parts.


If your HVAC system is 15 years or older and isn’t working correctly, call AVS Heating & Air Conditioning Service to see how quickly and efficiently you can replace it.
