What to Do If The Coils Freeze on Your AC Unit — Quincy, MA

RTM Design • Oct 19, 2021

At Trust 1 Services, a common problem that we often help Quincy, MA, homeowners resolve is frozen coils on their AC unit. When your condenser coils freeze, they can make your AC less efficient or cause your unit to stop functioning entirely.

Not having a functioning air conditioner in the summer can be brutal. Excessive heat makes you and your family uncomfortable and decreases the quality of your life.

We recommend that you resolve your AC problem as soon as possible. Unfortunately, most homeowners do not know how an air conditioner functions. That is where our company, Trust 1 Services, comes into play.

Our talented technical team at Trust 1 Services specializes in providing top-notch fixes to common residential HVAC problems. If you are unsure of the cause of your AC troubles, we can send one of our top-grade technicians to inspect your cooling system.

If you require a more efficient cooling system, we can also repair or replace your AC.

How to Know If You Have Frozen Coils in Quincy, MA

To confirm whether you have frozen condenser coils, check your supply registers (vents). If they are warm, that is a clear indication of a coil freeze. If you know how to open your panel, you will most likely see your AC unit’s coils frozen. Call an HVAC technician at Trust 1 Services immediately.

Here are possible causes and things you can do to resolve frozen coils on your HVAC unit.

Causes of Frozen AC Coils

Blocked Air Flow
One of the most common reasons for coil freezes is blocked airflow. All air conditioning units rely on a consistent airflow between your HVAC system and the outside of your home. When a blockage occurs, humidity settles on your coils, eventually causing your coil to freeze.

Sometimes, all you need to do to resolve a blocked airflow issue is to clean or replace your AC filters. Over time, filters become clogged with dust and other debris, causing your AC unit to lose efficiency.

If cleaning or replacing your filters does not resolve your air conditioning issue, contact a Trust 1 Services professional HVAC contractor in Quincy, MA, immediately.

Refrigerant Leaks
Otherwise, perhaps you are experiencing a refrigerant leak or mechanical issue that can stall your cooling system.

The purpose of a refrigerant is to regulate the temperature in your HVAC unit. When refrigerant levels are too low, you may experience freezing. These types of leaks are often critical, and it may be a sign to invest in a new HVAC unit.

However, you should hire a professional AC technician from Trust 1 Services to diagnose your mechanical issue. Other mechanical problems that could cause your coils to freeze include fan malfunctions, kinked refrigerant lines, and more.

Cool Massachusetts Summers

One cause of frozen evaporator coils that many Greater Boston homeowners do not think about is the weather during the summer. If your city is experiencing an abnormally cool summer, it can confuse your HVAC system.

Manual air conditioning units rely on weather patterns to work efficiently. When there is a break in that pattern, and you do not adjust your thermostat, your coils may freeze. Often, changing your AC filters is the best way to resolve this issue.

Troubleshooting Methods

Here are some troubleshooting methods that may help you resolve your frozen coil issues with and without professional help from our team at Trust 1 Services in Quincy, MA.

How to Fix Blocked Air Flow Problems

If you notice debris blocking your AC filter, the first thing you should do is power down your frozen air conditioner. This shutdown will allow your HVAC unit to defrost properly. We recommend letting your cooling system rest for a couple of hours before proceeding with the filter change.

When you are ready to change your clogged air filters, flip on your AC unit’s fan for an hour. Our plumbing contractors recommend that you replace your cooling system’s filter every month and a half.

If you require assistance replacing your filters, give our team at Trust 1 Services a call, and one of our contractors can do it for you.

After you clean your filters, your AC should return to form. If not, there could be a deeper issue at play. Consult with a local Quincy HVAC technician from Trust 1 Services to figure out the cause of your problems.

How to Fix Refrigerant Leaks

Refrigerant leaks are tricky to resolve without professional assistance. Also, refrigerant is dangerous for an HVAC novice to handle. It can harm your and your family’s health if you do not control it.

If something is wrong with the mechanics of your air handler, we advise you to call us to handle it. We offer routine, periodic tune-ups that help prevent these leaks from occurring.

It is wise to invest in an annual AC maintenance service.

How to Fix Temperature Problems

One of the best ways to regulate your home temperature problems is to invest in a programmable thermostat. These thermostats automate your home AC unit, ensuring that your cooling system never overworks itself.

If you do not have a programmable thermostat, you must be vigilant when observing the temperature outside. When you run your AC too often, you set yourself up for HVAC issues.

On comfortable nights, to conserve energy, open your windows instead of running the air conditioner.

If there is a disconnect in the signal between your thermostat and your AC unit, call our plumbing company for professional assistance.
