What are the top reasons homeowners need air conditioning services? With hot summer weather on the horizon, take a look at the AC issues that require professional attention.
A frozen evaporator coil won't fix itself. The coil draws heat out of the air and helps to cool your home. Even though the coil is cold, it shouldn't freeze. Excessive moisture or restricted airflow can lead to this common AC issue. The result is visible ice (if you know where to look), noticeable condensation, or lack of cool air.
If your AC system runs but doesn't cool, a frozen coil is a possible culprit. The longer you let a frozen coil go, the worse the condition could get. If left untreated, the problem could result in permanent damage to your home's air conditioner.
Whether you can see ice forming on the coil or you suspect this issue, an HVAC professional can inspect the system, diagnose the problem, and recommend a repair or replacement.
The refrigerant removes heat from the air to effectively cool your home. Without enough refrigerant, the air conditioner can't function properly. This can result in a loss of cooling power. Common signs of a refrigerant leak include hissing sounds (from the indoor part of the air conditioner), warm air when the air conditioner runs, and high electric bills.
Air conditioner refrigerant is a chemical the novice do-it-yourselfer homeowner should never handle. If your air conditioner uses HCFC-22 refrigerant, choose an HVAC contractor who is Section 608 certified. This designation is a requirement for contractors who service any AC unit containing HCFC-22 refrigerant under the Clean Air Act.
The thermostat may not seem like a major part of your home's HVAC system. But without a functional thermostat, your air conditioner won't know when to turn on or off. If you have an older thermostat, your air conditioner doesn't respond to the thermostat's setting, or the thermostat has clear signs of wear and tear, it's time to replace it.
Like other AC services, a thermostat replacement is a job for a professional. Incorrect placement or installation can reduce the device's effectiveness and raise your energy-related costs. Not only can the HVAC contractor replace the thermostat, but they can also recommend newer technology (such as programmable or smart thermostats) that add to your home's energy efficiency.
When should you call the contractor? Don't wait until your AC system completely shuts down. Save yourself time, energy, and potentially money with an early repair or replacement.
