The Most Common HVAC Repairs & What They Cost

Your HVAC system is crucial to maintaining a comfortable home or business environment, especially during extreme weather conditions. However, like all mechanical systems, HVAC units can experience wear and tear over time, leading to unexpected breakdowns. Understanding the most common HVAC repairs and their associated costs can help you prepare for when something goes wrong and prevent costly surprises.

At D-N-D Services, we’ve been providing HVAC repair services in Rockwall and the surrounding areas since 1997. Whether you’re experiencing issues with your air conditioning, heating, or ventilation, we’re here to help. Let’s break down the most frequent HVAC repairs and what you can expect to pay for them.

Air Filter Replacement

While not a complex repair, replacing a dirty or clogged air filter is one of the most common HVAC tasks. A dirty filter reduces airflow, causing your HVAC system to work harder and potentially overheat. It can also lead to poor indoor air quality and increased energy bills.

Cost: Replacing an air filter is inexpensive, typically ranging from $20 to $50, depending on the type and size of the filter. It’s a relatively easy repair that homeowners can perform themselves. However, if you’re calling a technician for routine maintenance, the cost might be included in the service fee.

Refrigerant Leaks

In air conditioning systems, refrigerant plays a crucial role in the cooling process. If your air conditioner isn’t cooling as effectively as it should, it might be low on refrigerant due to a leak. Low refrigerant levels can lead to system malfunctions and even compressor damage if left unaddressed.

Cost: The cost to fix a refrigerant leak depends on the location and size of the leak. Fixing a leak typically costs between $225 and $1,000. If the refrigerant needs to be recharged, that can add $100 to $150 to the total bill.

Thermostat Malfunctions

Your thermostat is the brain of your HVAC system, controlling when it turns on and off based on the temperature you set. A malfunctioning thermostat can cause inconsistent temperatures in your home or prevent the system from running altogether. This could be due to dead batteries, faulty wiring, or simply an old unit that needs replacing.

Cost: If you need a new thermostat, you can expect to pay anywhere from $100 to $500 for the unit, depending on whether you opt for a basic model or a smart thermostat. Professional installation typically costs between $100 and $200.

Dirty Coils

Both the evaporator and condenser coils in your HVAC system can accumulate dust and debris over time, reducing the system’s efficiency. Dirty coils make it harder for the system to cool or heat your home, increasing energy usage and wear on the system.

Cost: Cleaning the coils is an essential maintenance task, and the cost to clean them typically ranges from $100 to $400, depending on the complexity of the job. If the coils are severely damaged and need to be replaced, the cost can rise significantly—up to $1,000 or more.

Blower Motor Problems

The blower motor is responsible for circulating the air throughout your home, pushing cooled or heated air through the ductwork. If the blower motor malfunctions, your HVAC system won’t function properly, and airflow can be restricted. The motor may wear out over time or get damaged due to dirt and debris buildup.

Cost: Replacing a blower motor can be expensive. The cost for parts and labor typically ranges from $400 to $1,200, depending on the make and model of your HVAC system.

Capacitor Failure

The capacitor is a small but important component that helps your HVAC system start up and run smoothly. When the capacitor fails, the system may have trouble starting, or it might stop working altogether. Symptoms of a failing capacitor include strange sounds, intermittent cooling, or a complete lack of airflow.

Cost: Replacing a capacitor generally costs between $100 and $400, depending on the type of HVAC system and the complexity of the repair.

Compressor Failure

The compressor is one of the most expensive components in an air conditioning unit. If it fails, your system may stop cooling altogether. Compressor failure can be caused by low refrigerant, electrical problems, or general wear and tear. This is one of the most serious and expensive HVAC repairs.

Cost: Replacing a compressor can cost anywhere from $1,200 to $2,500, depending on the system and labor costs. In many cases, if the compressor fails, it may be more cost-effective to replace the entire air conditioning unit, especially if the system is already aging.

Leaking Ductwork

Leaky ducts can prevent conditioned air from reaching certain areas of your home, resulting in uneven temperatures and higher energy bills. This is a common issue in older homes or homes with poorly maintained ductwork. Leaks can be caused by poor installation, wear and tear, or damage to the ducts.

Cost: Duct repair costs typically range from $300 to $2,000, depending on the extent of the damage and whether duct replacement is necessary.

Pilot Light or Ignition Problems (For Heating Systems)

For heating systems like furnaces, a malfunctioning pilot light or ignition system can prevent the unit from turning on or maintaining consistent heat. This is a common issue during the colder months when heating systems are working harder. It could be due to a dirty pilot light, faulty thermocouples, or electrical problems.

Cost: Repairing or replacing the ignition system typically costs between $150 and $400. If the furnace is older, you may need to replace the entire ignition system, which could cost between $400 and $1,000.

Conclusion

While HVAC repairs can be costly, many of these issues can be prevented with regular maintenance. At D-N-D Services, we recommend scheduling annual tune-ups to keep your system running smoothly and avoid unexpected breakdowns. Proper maintenance can also help extend the lifespan of your HVAC system, saving you money in the long run.
