Pre-season servicing slots are open through October and November — book a coil wash before the heat returns.

Prism Room services air conditioning in homes and small workplaces. Every visit ends with a measured airflow reading, a photographed filter and a written note of what we found inside the unit.
Reading the room
Most calls start with one of these six complaints. Here is what each one normally points to, so you know roughly what you are booking before anyone opens a fascia.
Dust packs the filter mesh and then the fins behind it. The unit still cools, it just cannot push the air far enough into the room.
Usually a slow refrigerant leak or a coil that freezes over and blocks itself. We pressure test rather than simply topping the gas up.
Condensate is backing up because the drain line is blocked, or the indoor unit has drifted off level. Both are fixable on a single visit.
Damp dust grows on the blower wheel and in the pan. Surface spraying hides it for a week; the wheel has to come out and be washed.
If the noise rises and falls with fan speed, it is mechanical — a dry bearing, a loose bracket or debris touching the wheel.
Often a tired start capacitor or a compressor drawing too hard. Leave the unit off and book a fault visit rather than resetting repeatedly.
Not sure which one fits? Describe what the unit is doing in the booking form and we will tell you which service it needs — including when the honest answer is that it does not need one yet.
Three levels of service
Servicing is not one job. Choose by symptom and by how long it has been since the last wash, not by habit.
01
Every 3 months · routine
Best forUnits that still cool well and are washed on schedule.
02
Yearly · or when airflow drops
Best forWeak airflow, musty smells, or a first service in over a year.
03
Every 3–5 years · deep
Best forNoisy units, repeat water leaks, or long-neglected systems.
Something has stopped working altogether? Book a fault visit instead. We diagnose first and quote the repair before touching it — a wash will not fix a failed capacitor or a leaking coil.
On the day
The same four steps every time, in homes and in offices, so you know what the hour will look like.
Floors and furniture covered, power isolated at the breaker before any panel comes off.
Airflow and the temperature split are recorded as found, so there is a number to compare against afterwards.
Filters, coil and blower cleaned to the level you booked; the drain line is flushed and watched until it runs clean.
Second reading taken, filter photographed, and anything worth watching noted — with a suggested date for the next wash.
Coverage
Residential and small commercial systems, whoever installed them. If your unit is not on this list, ask — we will say plainly whether it is ours to work on.
We service, clean and repair. We do not sell units, and we will not recommend a replacement when a wash and a bearing will do.
Straight answers
If yours is not here, add it to the note field when you book and we will answer before we schedule anything.
A general service every three months suits most homes running the unit daily. Light or seasonal use can stretch to every six months, with a chemical wash once a year.
If the unit still cools quickly and was washed in the last few months, a general service is enough. If airflow has dropped, it smells on start-up, or it has been over a year, go chemical.
Often, yes — most slow cooling is a blocked filter or coil. If the readings after cleaning still fall short, the cause is refrigerant or electrical, and we will tell you that rather than selling another wash.
Allow 45 to 90 minutes per unit. Someone should be there to let us in and to hear the findings at the end, but you do not need to watch the work.
If the noise comes from debris or an unbalanced blower wheel, cleaning fixes it. A dry bearing or a cracked mount needs the overhaul, since the part has to be reached and replaced.
Switch the unit off to stop the damage and book soon. It is usually a blocked drain or a unit sitting off level; both are quick to put right once the panel is open.
Yes. Most of our work is on systems installed by someone else. We note the brand and model on the first visit so later services go faster.
No. A sealed system should not lose gas, so a low charge means a leak. We pressure test and find it; routine topping up only hides the problem until next season.
Booking
Tell us the unit and what it is doing. We reply with a time window and the scope of work, so there are no surprises when we arrive.
