Try These Quick Fixes Before Calling Comfort Monsters

Do a quick review of the basics

If you look at your thermostat and it says (not blinks) “heating” and nothing is happening, give us a call.

Inspect the air filter for clogging

Air filters need to be changed or they’ll impact your blower’s life. Check your filter and replace it to see if your airflow increases.

Reset the HVAC breaker

Sometimes, all you need is a quick reset. Go into your breaker box, find the large breaker, often 30 or 60 amps, that’s labeled heat and switch it off. Wait a minute or so and switch it back on to be sure it works.

Check if vents and registers are fully open

Weak airflow and uneven heat may be a simple fix. Open all of your vents to see if that’s the culprit.

Common HVAC Repair Issues We See in Raleigh

  • Weak or No Airflow: The problem? In most cases, it’s a clogged air filter or a worn blower motor.
  • HVAC Running But Not Working: You might need a new thermostat or compressor. Finding the exact cause is tricky. Our monsters can help.
  • Refrigerant Leak: Leaks make it harder for your system to do its job.
  • Frozen Outdoor Unit: This can happen if your coils are dirty or refrigerant levels are low. It needs quick attention to prevent more serious damage.
  • Loud Noises Or Unusual Vibrations: Do you hear strange sounds? These are warning signs of bigger issues. Loose components or a dying motor are two potential causes.

Common Signs Your HVAC Needs Replacement

Weak or No Airflow

What is the problem?

Air is either barely coming out of your vents or has stopped entirely, making it impossible to maintain a comfortable temperature in your home.

What caused it?

This is usually caused by a heavily clogged air filter restricting flow or a blower motor that has worn out and can no longer push air through the ductwork.

Will it happen again?

With regular filter changes every 30–90 days, you can prevent most airflow issues. However, mechanical parts like motors will eventually reach their end-of-life.

Unit Running But Not Cooling

What is the problem?

Your HVAC system is powered on and humming away, but the air blowing through the house isn’t actually cold.

What caused it?

The culprit is often a miscalibrated thermostat or a failing compressor. Because so many different components can cause this, a professional “Monster” diagnostic is usually required.

Will it happen again?

Electrical components like thermostats can fail due to age, but keeping your outdoor unit clear of debris helps protect the compressor from overworking and failing prematurely.

Refrigerant Leak

What is the problem?

Your system is losing the “coolant” it needs to remove heat from your home. This forces the unit to run longer cycles while producing less cooling.

What caused it?

Leaks typically develop over time due to formicary corrosion (pitting in the copper coils) or vibrations that cause connections to loosen and crack.

Will it happen again?

Simply “topping off” the refrigerant is a temporary fix. Unless the leak is found and sealed, the refrigerant will continue to escape until the system fails again.

Frozen Outdoor Unit

What is the problem?

Ice has physically built up on your outdoor coils or brass refrigerant lines, even when it’s hot outside. This effectively “insulates” the unit against doing its job.

What caused it?

This is typically triggered by restricted airflow (dirty coils/filters) or low refrigerant levels, both of which cause the coil temperature to drop below freezing.

Will it happen again?

If the underlying airflow or leak issue isn’t resolved, the unit will likely freeze up again within hours of the ice melting.

Loud Noises or Vibrations

What is the problem?

Your system is making unusual sounds—like banging, screeching, or buzzing—or you can feel the unit vibrating through the walls.

What caused it?

These are warning signs of mechanical distress. It could be something as simple as a loose fan blade or as serious as a motor bearing failing or a compressor “slugging.”

Will it happen again?

Mechanical noises rarely go away on their own; they usually get louder until the part fails completely. Early intervention prevents a small noise from becoming a total system replacement.

What Our Clients Say About Us

Just had my first experience with Comfort Monster and it was all it had been cracked up to be. From initial inquiry through service call and payment -- the emphasis on technology was noticeable and awesome (including the text message telling me that the technician had just pulled up at my house!). Props for bringing a tired industry a fresh face!

I was so pleased with their service that I switched my annual maintenance contract over to them. The technicians are experts in their field and very professional in delivery of their service. What surprised me the most was the amount of information they provided to me about my systems, not only verbally but in a very detailed written report. They also provided options as to short term and long term maintenance and replacement options ... I felt I could trust they were providing me the information I needed to make the best choice for me, rather than trying to upsell me.

We were very pleased with Comfort Monster's attention to detail, thorough cleaning, & system check. With other companies, we have never received such detailed reports/explanations. We were also pleased that they reported our old system seems to be in generally good shape. We highly recommend them!

FAQs

How long does HVAC replacement take?

The installation of a new system can take anywhere from a few hours to a few days. The most common amount of time actually installing the system on site is 1 day (8 am to 5 pm). Complicated setups may take longer. We’ll discuss the timeline during our visit.

When is HVAC replacement better than repair?

It may be time to replace your furnace if:

  • Repairs are more frequent
  • Your system is 12+ years old
  • Your energy bills are higher than usual

Newer systems with minor issues are ideal for repairs.

Do you offer financing for HVAC replacement?

Yes. We know that no one ever plans for their HVAC system to break down. We take the stress out of replacement by offering financing options that fit your budget.

Will a new HVAC system lower my energy bills?

Yes – especially if your current unit is 10+ years old. Modern systems are much more efficient. That means lower energy costs for your family.

Do you remove and dispose of the old HVAC system?

Of course. Our Monster Techs will handle the removal of your old unit to make the process – and your life – easier.
