We Solve AC Problems Other Companies Can’t

Many of our new customers call us after several failed attempts with other HVAC companies. Whether those technicians couldn’t accurately diagnose the issue or simply replaced parts without fixing the real problem, Comfort-Tech is often the company that finally gets it right.

Our experienced team takes pride in diagnosing even the most complex air conditioning and heating issues. We don’t guess — we troubleshoot thoroughly to uncover the root cause of the problem.

Free Second Opinions on Major AC Repairs

Already had your AC inspected and want a second opinion? If you’re in Alexandria or the surrounding Northern Virginia area and facing an expensive repair, give us a call. We provide free second opinions on major repairs like out-of-warranty motors, compressors, coils, and other high-cost components. Misdiagnoses on critical parts—especially compressors—are more common than you might think. Our experienced, trustworthy technicians will give you a clear, accurate assessment and honest recommendations based on what we find.

Sometimes a failing major component signals it may be time for a full system replacement—particularly if your unit is 10 to 15 years old. Spending thousands to repair an older, inefficient system often isn’t the most cost-effective solution. Many new parts only come with a 1-year manufacturer warranty, and other components could be nearing the end of their life, potentially leading to more costly repairs later.

Our technicians will evaluate your system thoroughly, explain your repair options and costs, and help you decide if replacing the unit is the smarter choice. If a replacement makes sense, we’ll provide a free, customized quote for a new AC system designed for your home’s size, layout, and ductwork. We also offer 0% interest financing to make upgrading easier and more affordable.

Residential AC Repair Tips for Homeowners in Northern Virginia, VA

How to Tell If Your AC Needs Repair

Living in Alexandria and the surrounding Northern Virginia area means dealing with hot, humid summers, so a failing air conditioner is hard to ignore. Watch for these common signs that your AC may need professional attention:

• Unusual noises such as grinding, buzzing, or hissing

• Sudden increases in your energy bill

• Longer run times than normal

• Visible problems like frozen coils or water leaks

• Strange odors coming from the unit

• AC fails to turn on

Steps to Take if Your AC Breaks Down

If your air conditioner or heat pump stops working, try these quick checks before calling for service:

• Ensure your thermostat is set to “Cool” mode.

• Make sure the temperature setting is lower than the current room temperature.

• Inspect your AC components, including the outdoor condenser and indoor air handler or furnace.

• Check circuit breakers and reset any that have tripped.

• Examine the air filter and replace it if it’s dirty or overdue for a change.

If your system still isn’t cooling properly after these steps, it’s time to schedule professional AC repair. Contact Alexandria Heating & Cooling to get your system running efficiently again.

Preparing for Your AC Repair Visit

To help your service visit go smoothly, consider these tips:

• Take photos of your equipment’s model and serial numbers to share with our team. This helps us identify your system’s age, warranty, and possible issues ahead of time.

• Follow any instructions from our dispatchers to prepare your home.

• Clear the area around your outdoor unit, air handler or furnace, breaker panel, thermostat, and attic access so technicians can work without obstruction.

• Secure pets to keep everyone safe and prevent distractions.

• Keep your phone nearby—sometimes we can arrive earlier than expected and will need to confirm you’re home.

Following these steps helps our technicians get your AC back in top condition quickly and efficiently.
