The AquaCal SQ145 heat pump is built to serve medium and large residential pools with strong and reliable performance. It delivers a higher BTU output compared to smaller models and is often used in homes that require rapid heating or consistent pool temperature throughout the year. While this model is engineered to perform in Florida’s challenging climate, that does not mean it is immune to performance issues or wear over time.

Pool heaters work hard behind the scenes, and like any high demand appliance, they eventually require service. Whether your AquaCal SQ145 is suddenly not producing heat, shutting off unexpectedly, or just not keeping up like it used to, we are here to help. Our licensed service team offers professional diagnostics, efficient repairs, and trusted guidance on how to keep your pool comfortable without unnecessary replacements.

Homeowners across the region turn to us for heater diagnostics, repairs, and full system replacements.
This system is known for durability, but that does not mean it is
Over time, even the most dependable heater will start to show signs of wear. For many homeowners, the first symptom is inconsistent heating. One day your pool warms up without a problem, but the next day the system struggles to reach temperature or shuts off early. In other cases, the issue may be more obvious. You might hear a loud humming or grinding sound from the unit. You might see an error message flash on the control panel. Or the heater may stop working entirely.
These issues are not random. They are signals that the system needs service. The SQ145 is designed to run efficiently with minimal disruption, so any change in sound, performance, or reliability should be evaluated. A small issue, like a miscalibrated sensor or minor refrigerant leak, can escalate quickly if ignored. Electrical components can fail gradually, putting strain on the entire system and creating the risk of a complete shutdown during peak season.
The Florida climate also contributes to premature wear. Salt air, intense humidity, and inconsistent power quality can all impact heater function. These conditions make preventative service and timely repairs even more important.
The AquaCal SQ145 is a high output heat pump capable of delivering approximately 135000 BTUs. It uses R410A refrigerant and features a titanium ThermoLink heat exchanger that is specifically designed to resist corrosion from saltwater systems and imbalanced pool chemistry. This unit supports a wide range of water flow rates and includes advanced digital controls with built in diagnostics.
Its quiet operation is powered by a scroll compressor, and the cabinet is constructed for outdoor durability. It fits within standard pool pad dimensions and integrates with most automation systems. All of these features make the SQ145 a favorite among homeowners who want fast, reliable pool heating with minimal disruption.
However, even with all these advantages, regular maintenance and expert repairs are still essential to preserve long term performance.
When your SQ145 is not performing as expected, we begin with a full inspection of the unit and its operating conditions. This includes checking refrigerant pressures, monitoring compressor performance, testing water flow rates, and reviewing the electrical system. We examine the control panel, sensor inputs, and internal wiring to ensure everything is working in sync.
If there is a part failure, we explain what has failed, why it happened, and what needs to be done to restore proper function. We do not offer guesses or vague recommendations. We provide clear findings and realistic solutions based on what we see.
In many cases, the repair is straightforward. A failed capacitor or faulty contactor may be preventing startup. A flow sensor might be blocked or reading incorrectly. The coil may be dirty or the refrigerant level may be low. These are common service needs that we resolve quickly. Our goal is to get your heater running efficiently again without delay.
If parts are needed, we source directly from AquaCal’s preferred supply channels to ensure the components meet factory standards. We also test the unit thoroughly after each repair to make sure the problem is resolved, not just patched.
If your AquaCal SQ145 is under ten years old and has been reliable up to this point, we almost always recommend repair as the first option. A well maintained heater can deliver solid performance for many years. However, if your unit is requiring more frequent service, failing to maintain heat efficiently, or has developed multiple unrelated problems, we may recommend reviewing your upgrade options.
An aging system that needs multiple repairs in the same season may cost more to maintain than it would to replace. The decision depends on the specific condition of your heater and how it aligns with your pool’s current demands.
We do not pressure you to replace a system that still has life in it. Instead, we offer a transparent cost comparison between repairing the existing unit and replacing it with a newer, more efficient model. Our goal is to help you make a decision that serves you over time, not just in the moment.
Even if your SQ145 is currently working well, regular service can help prevent future problems. We recommend annual inspections before peak season to make sure your system is clean, responsive, and operating at full efficiency.
This preventative maintenance approach helps catch problems early, extends the life of your components, and ensures that your heater is ready when you need it most. It is much easier and more affordable to fix a small issue now than to replace an entire system later because of avoidable damage.
If you have not had your heater serviced recently, now is a great time to schedule a checkup.
