Warning Signs

Signs Your HVAC System Needs Repair

Don't ignore these symptoms — catching problems early saves money and prevents full system failure.

Warm Air from AC

Your AC is running but only pushing warm or room-temperature air — often a refrigerant or compressor issue.

Strange Noises

Banging, screeching, rattling, or clicking from your system are signs of mechanical problems that will worsen if ignored.

Spiking Energy Bills

A sudden increase in your utility bill without a change in usage is a classic symptom of a system working harder than it should.

Short Cycling

If your system turns on and off rapidly without completing a full cycle, it's usually a refrigerant, thermostat, or electrical fault.

Uneven Heating or Cooling

Some rooms too hot, others too cold? This points to ductwork issues, a failing blower motor, or zoning system problems.

No Heat in Winter

A furnace that won't start, won't stay lit, or only blows cold air in winter requires immediate professional attention.

Water Leaks or Ice Buildup

Water pooling around your HVAC unit or ice forming on the coils signals refrigerant issues or a clogged condensate drain.

Burning or Musty Odors

Burning smells can indicate overheating electrical components; musty odors often signal mold growth in ducts or coils.

FAQs

Frequently Asked Questions About HVAC Repair

Honest answers to the questions we hear most often from Capital Region homeowners.

How quickly can ALJ Heating & Cooling respond to an HVAC repair call?

We understand that a broken HVAC system isn't something you can schedule around. We keep our calendar flexible specifically to accommodate urgent repair needs. Call us at 518-416-3356 and we'll do our best to get someone to you the same day — including on weekends when possible.

What HVAC systems does ALJ repair?

Our technicians have experience with Carrier, Trane, Lennox, Rheem, York, Goodman, American Standard, Bryant, Heil, Bosch, Mitsubishi, Daikin, and more. We carry common repair parts on our trucks to complete most jobs in a single visit.

Do you offer free estimates for HVAC repairs?

Yes — ALJ Heating & Cooling provides free estimates for HVAC repair and replacement projects. Use the Free Estimate button or call 518-416-3356.

We believe in transparency. Before any work begins, we'll diagnose the issue, explain what we found in plain language, and give you a clear written estimate. There are no surprise charges on your invoice — what we quote is what you pay.

How do I know if I should repair or replace my HVAC system?

Use the "5,000 rule": multiply the system's age by the repair cost. If the result exceeds $5,000, replacement is usually the smarter investment.

As a general rule, systems over 15 years old that require major repairs — compressors, heat exchangers, coils — are typically better candidates for full replacement. A new high-efficiency system can pay for itself in energy savings within a few years. Our technicians will give you an honest, no-pressure assessment of your options every time.
