What Your Neighbors Are Saying About Us

Replaced the old with the new. I got a fantastic price on the new heat pump system. The installation went really smoothly, and it is working great. I like this company.

We’ve been clients of Ellis for 20+ years at our home and office. Yesterday we woke to no heat, of course with the coldest temps of the year just 2 days away, we called Ellis.

Ellis air installed an infinity heat pump system at our home 15 years ago. Best thing we have ever done. It has preformed beautifully over the years and is still going strong thanks to Ellis Air.

Jesse came for my semi annual heating checkup. He was prompt, calling ahead to say he was on his way. He was very thorough and explained everything he did.

I highly recommend Ellis Air & Heat. Larry Hatley service Technician came out and checked the unit out. Larry is one of the most pleasant, delightful person to deal with.

Warning Signs Your Ductless Mini Split Needs Attention

Ductless mini splits are reliable systems, but like any mechanical equipment, they can develop problems over time. Catching an issue early usually means a simpler, less expensive repair. If you notice any of the following, it’s worth scheduling a service call before the problem gets worse.

Your system is running but the space isn’t reaching the temperature you’ve set, which can point to a refrigerant issue, a dirty air handler, or a failing compressor.
You’re hearing unusual sounds such as clicking, rattling, grinding, or hissing that weren’t there before.
The indoor unit is leaking water or producing excess condensation, which is often caused by a clogged drain line or improper installation.
You notice ice forming on the indoor unit or the refrigerant lines, a sign that airflow or refrigerant levels may be off.
The system is short-cycling, meaning it turns on and off frequently without completing a full heating or cooling cycle.
There are unusual odors coming from the unit, which can indicate mold growth inside the system or an electrical issue that needs immediate attention.
The remote or wall control is unresponsive, or the system is behaving inconsistently despite correct settings.

In Dallas, where summer heat and humidity push cooling systems to their limits for months at a time, a struggling ductless unit can deteriorate quickly if the underlying issue isn’t addressed. Don’t wait until a minor repair turns into a full replacement.

Ductless Mini Split Problems We Commonly See

Our technicians work on ductless systems regularly and are familiar with the full range of issues these units can develop over time.

Refrigerant leaks are among the most common problems we see. Low refrigerant affects both cooling capacity and system efficiency, and the leak itself needs to be located and repaired before the system is recharged.
Dirty or clogged air filters and coils restrict airflow and cause the system to work harder than it should, leading to reduced performance and potential component damage over time.
Drainage issues, including clogged condensate drain lines, can cause water to back up inside the unit and leak into your living space.
Electrical faults, including problems with the control board, capacitors, or wiring, can cause erratic behavior or complete system failure.
Sensor and thermostat problems can prevent the system from reading room temperature accurately, causing it to run inconsistently.
Compressor issues are more serious and often develop after years of heavy use, particularly in a demanding climate like Dallas where systems run for extended periods throughout the year.
Fan motor failures in either the indoor or outdoor unit can reduce airflow and cause the system to overheat or ice over.

Frequently Asked Questions

How do I know if my ductless mini split needs repair or replacement?

Our technician will assess the age of the system, the nature of the problem, and the cost of repair relative to replacement value. We’ll give you an honest recommendation based on what actually makes sense for your situation.

Do you repair all brands of ductless mini splits?

Yes. Our technicians are trained to work on ductless systems from all major manufacturers, not just the brands we install.

How quickly can you get to me if my system stops working?

We offer 24/7 emergency service for situations where your system has failed completely. For standard repair calls, we work to schedule service as quickly as possible.

Can high humidity in Dallas cause problems with my ductless system?

Yes. High humidity increases the workload on your system and can contribute to drainage issues, coil problems, and mold growth inside the air handler. Regular maintenance helps prevent these issues from developing.

How can I avoid frequent repairs on my ductless mini split?

Annual maintenance is the most effective way to extend the life of your system and catch small problems before they become larger ones. Keeping filters clean between service visits also makes a meaningful difference in performance and reliability.
