Why Is My Air Conditioner’s Refrigerant Line Covered In Ice?

An Austin tech explains,

Let’s say you’re mowing the lawn or pulling weeds. You’re looking forward to finishing up your chores so you can head inside and enjoy a nice, cool beverage in your nice, cool home. As you’re working, you glance over at your trusty AC unit, and something looks… unusual. And by “unusual” what we mean is “frozen.”

Alarm bells go off in your head. “Oh. That can’t be good.”

You’re right. It’s not good when your AC unit “freezes up.” But don’t panic! If you see any frosty bits on the refrigerant line (or anywhere else, for that matter), there’s plenty you can do on your own before you call us.

Step 1: Thaw Your Unit

Turn OFF your AC, turn the fan setting to ON, and wait three of four hours. We know, we know: Turning off your AC when it’s sweltering isn’t anyone’s idea of fun. But neither is causing massive (expensive) damage to your AC system, right? So give the poor thing a chance to thaw out.

Step 2: Learn Some Quick HVAC Anatomy

When your refrigerant line is frozen, your indoor evaporator coil is probably also frozen.

The evaporator coil holds refrigerant, which is a liquid or gas that absorbs heat from warm air. (That’s right; AC units don’t really “add cold” to air; they actually “remove heat”!) If the refrigerant gets too cold, the moisture in the surrounding air freezes.

So, why would refrigerant get too cold? One of two reasons: low airflow over the coils or low amounts of refrigerant. (Spoiler alert: These are the two things you’re going to check in a bit.)

Step 3: Review The Don’ts

Damage to your HVAC system is costly and time-consuming. So as you’re going about your DIY business, make sure you avoid the following:

  • Don’t continue to operate your AC: Leaving your unit on despite the freeze-up may burn out the compressor and motor, which can lead to replacing the entire system.
  • Don’t scrape or pick off the ice: You’re more likely to damage your equipment. Allow it to thaw completely and naturally.
  • Don’t replace refrigerant yourself: We’ll say more about that in a bit.

Step 4: Check For Blockages

When it comes to frozen refrigerant lines, the best-case scenario is you have a blockage somewhere. Here are the places to check:

  • Air filters: Inspect your air filters and replace them if there’s any visible dirt. Check and replace as needed, at least once a month.
  • Supply vents: Open all supply vents—the vents that blow air out. Yes, even in the rooms you don’t use.
  • Return vents: Unblock any return vents—the vents that suck air in. These are most often blocked by furniture or curtains.
  • Dirty coils: Blockages can also happen on the evaporator coils themselves. If you’re mechanically inclined, you can carefully clean them yourself with compressed air, a brush, or mild detergent and water. Check your owner’s manual for details.

Step 5: Check Your Refrigerant

Despite conventional wisdom, refrigerant doesn’t get “used up.” That means if you’re low on refrigerant, you have a leak.

Ice on your refrigerant line is the #1 sign of a leak, but here are some others to pay attention to:

  • Higher-than-normal energy bills
  • Air coming out of your vents isn’t very cold
  • Bubbling or hissing noises from your HVAC unit

If you suspect a refrigerant leak, do not attempt to replace it yourself. It’s a toxic chemical that should be handled by Austin’s HVAC pros to protect your safety.

HVAC contractor Austin, TX, can help you with fall HVAC maintenance. Hutto’s days are getting shorter as we are approaching the end of summer. And now is the time to schedule fall maintenance. It probably isn’t your favorite thing to schedule routine HVAC maintenance. However, HVAC maintenance is essential for heating systems to perform at their best, and fall is the perfect season for this. 

You may be wondering why fall is the best time for HVAC maintenance. Here are a few reasons: 

The Time Is Right for Repairs

Cooler months are ideal for scheduling HVAC system maintenance if you want your system to run at its best. Your system will have to work harder than necessary if you wait till spring when the temperature is already rising. Additionally, HVAC contractor Austin, TX, helps you prepare your HVAC system in advance for cold winter days.

Get Ready for Winter Season

It’s a good idea to conduct a maintenance check before winter, as the summer is coming to an end. Problems can arise anytime. However, a routine maintenance check allows any operational issues to be addressed ahead of time, rather than causing the system to fail in the middle of winter.

Grande Air Solutions can help your heating system get ready for winter with fall maintenance by repairing and cleaning its components. 

Prevent Toxic Gas Leakage

The maintenance of your HVAC system before winter will save you money while protecting your family from harmful gases, such as carbon monoxide poisoning. Carbon monoxide poisoning can occur from leaky ducts if they are not repaired immediately. The presence of carbon monoxide in your home poses a serious health threat if you do not have a functioning carbon monoxide detector.

Carbon monoxide can be lethal if it leaks from your ductwork or furnace, which is why it’s crucial to have them repaired before winter begins. 

Clear Out Your Home Air 

You and your family will spend a lot more time indoors during the winter, which makes indoor air quality even more critical. You can ensure that your HVAC system is clean and debris-free this winter by scheduling maintenance with air conditioning repair Hutto service for the fall.
