Refrigerant Leak Repair & Recharge
McDaris AC & Heating provides full service refrigerant leak repair, including replacing broken seals and cracked refrigerant lines. If the refrigerant levels are low because of the leak, our technicians recharge ac refrigerant too.
Signs of a Refrigerant Leak
Signs that your air conditioning unit is low on refrigerant or is leaking refrigerant include:
- Loss in cooling power resulting in AC taking longer to cool
- Hissing or gurgling sounds caused by holes in your unit’s coils
- Frozen condensation on the unit’s coils as a result of low refrigerant not properly absorbing heat
- Higher electric bills
A repair technician can provide a quick fix for leaky refrigerant problems simply by adding more refrigerant to your AC unit, but properly diagnosing and repairing the cause of the refrigerant leak is necessary to provide long-term results.
Circuit Board Repair & Replacement
Our technicians will check your circuit board, testing connections to see if the circuits are blown. When possible, our contractors will repair the burned-out circuit board. If the board is broken beyond repair, our technician will need to disconnect and remove the damaged unit and replace it by installing a new circuit board.
Symptoms of a Blown Circuit Board
The most common sign of circuit board failure or a need for circuit board repair is if the blower motor or condenser fan stops blowing air. Your air conditioner’s circuit board provides power to the unit’s key components, so if the circuit board goes out, the air conditioning system will not function or cool as it should.
Fuses, Circuit Breakers and Relays
Designed to protect other AC components including the compressor pump and the fan motor, these electrical components are designed to “blow” if too much power tries to enter the AC unit.
Symptoms of Relay Failure or Blown Circuit Breaker
A common sign that a fuse, circuit breaker or relay is blown is when your air conditioning unit stops cooling AND there’s a humming noise coming from the ac unit. Blown relay, fuse, and circuit breaker repairs involve replacement of the broken part.
Thermostat Repair & Replacement
If you think your thermostat is bad or broken, first try changing the thermostat’s batteries. If changing the batteries doesn’t fix the problem, doesn’t help, it likely needs repairs. In some cases, the HVAC technician might need to replace your thermostat.
Signs of a Broken or Bad Thermostat
Common symptoms of a bad thermostat include:
- Air conditioner not turning on.
- AC will not turn off.
- Varying temperatures in different rooms of your home, office, or business.
- Unresponsive thermostat, or powerless thermostat panel.
If you experience any of these issues with your air conditioner’s thermostat, you should contact an air conditioning contractor for thermostat replacement or repair services.
Your AC’s compressor pump maintains pressure in the unit and keeps refrigerant flowing. The compressor pump is a complicated air conditioner part containing both electrical and chemical components. That is why only a skilled HVAC technician should troubleshoot compressor pump problems and determine if minor compressor pump repairs can bring the unit back into working condition or if you should replace the compressor pump with a new one.
Symptoms of a Bad Compressor Pump
Signs of compressor pump failure include rattling noises, rumbling or ticking sounds, refrigerant leaks, and/or reduced airflow and warmer air temperatures. Because the compressor pump is a complicated part containing both electrical components and chemicals, a skilled HVAC technician is needed to determine if minor adjustments can help bring the compressor pump back into working conditioner or if a replacement is needed.
Contractor & Capacitor Problems
A properly-working capacitor and contractor are necessary to maintain the life of your air conditioner’s more expensive fan motor and compressor pump. These two key AC parts work together to provide power to the unit’s fan and compressor pump. For this reason, contractor and capacitor replacement are often the most straightforward repair of this problem.
Signs of a Bad Capacitor
When capacitor repair is the culprit, you will likely notice warm air coming from your vents despite the fan still pumping air normally. If your ac vents are blowing warm air instead of cool air even though the thermostat is turned down to a low temperature, you likely have capacitor repair in your future.
Evaporator Coil Repair & Replacement
An evaporator coil acts as a heat exchanger, cooling down warm refrigerant that passes through it. Minor evaporator coil problems can be fixed by removing dirt and corrosion from the coil and getting the preventative maintenance (including evaporator coil cleaning) recommended by the manufacturer of your air conditioning unit. However, significant evaporator coil damage or cracked lines will necessitate full evaporator coil replacement including installation of new lines.
Symptoms of Broken Lines & Evaporator Coil Leak
Common signs that you need evaporator coil repair or replacement include:
- Leakage around your AC unit
- Air conditioner turning on and off frequently
- Sudden rise in humidity throughout your home, office, or store.
If you experience any of these issues, or a combination of these, it’s time to call a licensed HVAC contractor to see if you need evaporator coil replacement.
Condensing Unit Fan Motor
A working condensing unit fan motor is necessary to circulate cooled air throughout your home. Sometimes condenser fan motor issues can be solved by replacing fan motor components, but only an licensed AC repair technician should make the diagnosis. If the motor is broken beyond repair, you will need a contractor to replace the condenser unit fan motor.
Signs of a Broken Condenser Fan Motor
- Fan motors can start experiencing problems suddenly, often displaying symptoms of a problem such as:
- Hard start when the thermostat triggers the AC to turn on
- Buzzing or clanking noises while the unit is running
- Higher than normal electric bills.
Is your heating and cooling system displaying any of these symptoms? If you answered yes, it is time to call your local AC company for help.
Often condensate repairs can be as simple as cleaning out the pump or clearing a blocked pump. A condensate pump’s function in your air conditioning system is to pump out the wastewater byproduct that your cooling system generates. In some cases, the condensate drain lines can become clogged and backed up, or they can become broken or cracked and start leaking water inside your office, home or building. As with all other AC components, your HVAC technician may determine that the pump is beyond repair, and your only option is to replace the condensate pump.
Symptoms of a Broken Condensate Pump
Signs of a failing condensate pump usually include classic signs of a water leak like water spots on the ceiling below the emergency condensate drain pan, or rusty water seeping through drywall. In either instance, the problem signals an overflow of water around the unit. If you notice any of these symptoms, contact your AC contractor for help.
