Ontario pool serviceView service areasMore than an equipment problem
Your pool should be a place to enjoy.
Condensation, uncomfortable temperatures and recurring equipment problems can make an indoor pool difficult to manage. Replacing a component is not always the whole answer.
King Air looks at the relationship between the equipment and the space around it. From service and maintenance to a complex retrofit, we help you understand the options and choose a practical next step.
Why King Air
Specialist knowledge.
Practical recommendations.
Indoor pool systems are specialized, expensive and interconnected. King Air brings equipment experience and whole-system thinking to the decisions that matter.
Experience with continuity.
Long-term refrigeration and air-conditioning experience, delivered by a family-operated business built around dependability, respect and straightforward communication.
Dry-O-Tron knowledge.
Our family has maintained some of the same Dry-O-Tron systems for more than 30 years, including equipment many contractors rarely encounter.
Dectron, Seresco & PoolPak.
Equipment-specific service combined with an understanding of the heating, refrigeration, airflow and controls around the dehumidifier.
Start with the evidence.
When an existing unit can be economically repaired or improved, we will discuss that path before recommending a full replacement.
