Top 5 AC Issues and How to Fix Them

Jul 21, 2020

Newcomb and Company has been a trusted source of local HVAC repair for more than 65 years—so you could say we know a thing or two about keeping systems running as they should. In a recent blog post, our HVAC experts went over 5 of the most common air conditioning issues that residents experience during the summer season. This week, we are going to explore what it takes to fix these common AC problems.

AC Repair 1: Low Refrigerant Levels

Low AC refrigerant is often a sign that there is a leak in your system. Unlike other fluid leaks, this will not leave an obvious puddle of refrigerant. Instead, it will likely evaporate and cause your air conditioner coil to freeze. An AC technician will be able to easily detect where the leak is occurring, seal or replace the compromised part, and recharge your refrigerant to the proper levels. This will quickly and effectively restore your air conditioner functioning.

AC Repair 2: Ductwork or Distribution Problems

Ductwork issues often require professional service. Cleaning is available for blocked ductwork and repair is available for leaky ductwork. Once your HVAC system can properly distribute the air that it is producing, your unit will feel more efficient and effective.

If the distribution problem is contained to one area of the home (such as in a recent extension, in the garage, or the attic), you may consider a mini-split AC system (or a ductless unit) instead of a ductwork extension. Mini-split units are small, compact, and efficient AC systems that can be reversed to a heat pump in the winter. These units can be easily added to your home to heat and cool a contained area. Here is our guide to mini-split systems.

AC Repair 3: Thermostat Issues

When your home feels warmer than it should, your instincts might bring you straight to your thermostat. In a best-case scenario, your system may be turned up too high, turned off completely, or set to “heat” instead of “cool.” If this is the case, you simply need to adjust your thermostat settings for a quick fix.

Perhaps you find that your thermostat has a blank screen. This can be caused by a few separate issues. Some causes of thermostat blank screens are easy DIY repairs—such as flipping a breaker trip or replacing dead batteries—while others may require expert repairs or replacements. Here is our comprehensive guide to thermostat blank screen causes and solutions.

If it seems that your AC system is working properly but you need to turn it lower and lower to reach a comfortable temperature, you may need thermostat calibration. This is a quick process where a professional ensures that your thermostat is reading your indoor air properly so it can adjust the temperature according to your preferences. Thermostat calibration is included with your regular AC maintenance.

In a worst-case scenario, you may be due for a thermostat replacement. However, this offers an exciting opportunity for you to take advantage of the latest technology and upgrades—such as with a programmable thermostat.

AC Repair 4: Drain Line Issues

When drain line (or condensate line) blockage occurs, the obvious repair is to clear out this part of your system. There are two common approaches to drain line cleaning: vacuuming out your drain line or clearing it with a liquid solution.

Trying this repair in a DIY fashion can make your drain line problems worse or pose a threat to your system, so it is always recommended that you contact an expert for care. An AC technician will use professional-grade tools and solutions to ensure longer-lasting drain line care. Here is a closer look at everything you need to know about AC drain lines.

AC Repair 5: Broken Part or System

As we mentioned in our previous blog, your heating and cooling unit is a complex network of parts and systems. One small issue can lead to an entire system failure. To repair this problem, you must first find which part is not working properly. It could be your compressor, fan, motor, coils, electrical connection, or another AC part. This kind of diagnostic work often requires expert insight. Once you have found the source of the problem, your HVAC professional can discuss your options with you.

This repair may be as simple as replacing one small system part. However, depending on the overall condition of your unit, your system may not be worth repairing. Repeatedly replacing HVAC parts can cost you more long-term than a new system without the benefits that a new system offers. Here is a closer look at choosing between an HVAC system repair and replacement.

Preventing Air Conditioning Problems

Perhaps the best recourse for HVAC repairs is to prevent the problems from occurring in the first place. By administering manufacturer-recommended care, a professional technician can keep your unit protected from preventable issues. Regular HVAC system maintenance can help you keep your air conditioner working longer and detect any issues early—before they become major repairs.
