Is your air conditioning unit blowing warm air even though everything else seems to be working? The culprit might be low refrigerant. Refrigerant acts like the lifeblood of your AC system's ability to cool your home’s air. If our HVAC technicians suspect that the problem is with your refrigerant level, they will expertly check levels and pressure to see what is happening. If they're low, we'll safely top it up according to strict EPA guidelines. We'll also inspect your entire system for possible leaks—the usual suspects for low refrigerant levels. If we find a leak, we'll explain the solutions and costs to prevent future trouble.

Occasionally, the blower fan on the outside unit may stop spinning. There are a few potential causes for this to become a problem. Depending on your AC unit's age and service history, we would begin by inspecting the capacitor to determine if it's no longer working or damaged. If the capacitor checks out, the issue may be with the motor module. When diagnosing a blower fan problem, we meticulously examine all system components until we pinpoint the issue. This comprehensive assessment may include inspecting the control board, bearings, and even the thermostat. Once we identify the problem, we'll recommend the best course of action to get your blower fan working again.

A malfunctioning capacitor can adversely affect your AC system and should be replaced by a trained HVAC professional. Capacitors play a crucial role in electrical systems, ensuring a consistent current flow for the electronic components of your air conditioning system. While they are typically dependable and can maintain functionality for up to a couple of decades, prolonged use or exposure can lead to deterioration over time. Signs of a failing capacitor, such as leakage or swelling, may be evident upon visual inspection. If not readily apparent, we'll run a diagnostic to determine if the capacitor is performing its job. Rest assured, we'll install a new capacitor if that’s the issue, and it’ll be tailored to your system's specifications.

Regularly cleaning your outdoor cooling coils is essential for maintaining your air conditioning system's efficiency and effectiveness. Without regular inspection and cleaning, these coils can become less efficient at cooling because they can easily accumulate dust and debris from their exposure to the elements around your home. Our IAQ Medic team will inspect your AC coils and advise you whether a cleaning is necessary. Inspecting and cleaning your outdoor coils is a regular part of our maintenance plans, so you can always know that they will operate for you during hot Northern Virginia days and nights.

Moisture accumulation is common with active air conditioning systems, particularly during the humid summers we have here in Northern Virginia. Condensation drain hoses play a vital role in directing condensed water to a safe location. However, these hoses are prone to clogging, damage, and other issues that can impede the flow of water, potentially causing damage to your home. We'll inspect your pans and condensation lines for any signs of leakage and ensure the line is clear by blowing it out. Once cleared, the hose will effectively and safely drain condensate water to keep your system from leaking where you don’t want it.

Your air conditioner depends on maintaining cold coils to facilitate airflow, ensuring comfort on hot days and nights in Northern Virginia. A malfunctioning defrost control can lead to frost buildup on the coils, compromising your home's cooling and the overall health of your AC system. The defrost control panel, an advanced electronic component, detects icy buildup and initiates defrosting of the coils. An icy buildup is a sign that it has stopped working. Our skilled technicians can diagnose and replace a faulty defrost control panel with a new one that will keep the frost from building on your coils.

Compressors are the most important component in your overall air conditioning system. Because they are so important, they are designed for durability with an expected lifespan of ten to fifteen years of continual service. Over time, compressors will start to show signs of their age, especially in a hot climate like Virginia, where it can be tested to its limits. If you notice unusual noises or a complete failure of your compressor, it's crucial to reach out to us for an inspection so we can determine if it needs repairs or a replacement. Typically, if your compressor is over ten years old, upgrading to a new compressor and system may be more beneficial due to potential energy and repair savings. New systems with higher SEER2 ratings offer enhanced energy efficiency, potentially saving you money in the long term while providing years of reliable service.

Your thermostat serves as your primary interface for interacting with your air conditioning system, essentially acting as the control center for your home's heating and cooling. Over the years, thermostats have undergone significant advancements, particularly with the introduction of smart technology, revolutionizing home systems. However, problems with the electronic functions of a thermostat can impact your entire system’s ability to keep your home cool. Fortunately, our technicians are trained in dealing with the various thermostat models and can repair or replace a faulty unit. We’ll tell you what went wrong and answer any questions you might have about your thermostat.
