HVAC Installation, Repair & Maintenance Services

Heating, ventilation, and air conditioning systems keep homes, offices, and commercial spaces comfortable all year round, and when they break down or perform poorly, daily life and business operations feel it fast. Washing Machine Service handles the full range of HVAC work — new installations, breakdown repairs, routine servicing, and system upgrades — for homes, offices, restaurants, hotels, and warehouses. Whatever the appliance or system, the goal is the same: fast diagnosis, honest pricing, and a repair that actually lasts.

HVAC Installation

Getting a new HVAC system installed correctly from day one saves money and headaches down the line. A poorly sized or badly fitted unit will short-cycle, struggle to cool or heat evenly, and burn through electricity. The installation team starts with a site assessment — room size, insulation, window placement, and expected occupancy — before recommending a unit that matches the space rather than simply the cheapest or biggest option available.

Installation services cover split-unit air conditioners, multi-split systems for several rooms, packaged units for larger commercial floors, ducted systems, and ventilation extraction for kitchens and bathrooms. Every installation includes correct refrigerant charging, secure mounting, condensate drainage that won't leak onto ceilings or walls, and electrical wiring done to code so the unit isn't at risk of tripping breakers or causing a fire hazard. Once fitted, the system is tested under load, not just switched on and left, so any teething issues are caught before the technician leaves.

For businesses replacing outdated systems, there is also guidance available on right-sizing multi-zone setups so that different rooms or floors can run at different temperatures without wasting energy heating or cooling unused spaces.

HVAC Repairs

Most HVAC breakdowns fall into a handful of familiar categories: the unit is running but not cooling or heating, it is leaking water, it is making unusual noise, it trips the electrical circuit, or it simply won't power on at all. Each of these has a distinct set of likely causes, and diagnosis starts with narrowing those down rather than guessing.

A unit blowing warm air is often low on refrigerant due to a slow leak, or the compressor itself may be failing. Water leaking from an indoor unit is usually a blocked condensate drain or a frozen evaporator coil that has started to thaw. Noisy operation often points to a loose fan blade, worn bearings, or debris caught in the outdoor unit. Frequent tripping of the breaker suggests an electrical fault, a failing capacitor, or a compressor drawing too much current as it nears the end of its life.

Repairs cover gas refilling and leak repair, compressor replacement or repair, PCB and control board faults, fan motor replacement, thermostat and sensor issues, capacitor and relay replacement, drainage clearing, and full electrical fault-finding. Emergency call-outs are available for units that fail completely, particularly in commercial settings where a warehouse cold room or server room cannot be left without cooling for long.

Routine Maintenance & Servicing

A large share of HVAC breakdowns are preventable with regular servicing. Dust and grime build up on filters and coils over months of use, forcing the compressor to work harder than it should and shortening its lifespan. A standard service visit includes filter cleaning or replacement, coil cleaning on both the indoor and outdoor units, checking refrigerant pressure, inspecting electrical connections for wear, and testing the drainage system.

For offices and commercial premises with multiple units, a maintenance contract is usually more economical than reactive repairs, since a technician catches small issues — a slightly low refrigerant charge, a fan starting to wear — before they turn into a full breakdown that shuts a system down entirely. Seasonal servicing ahead of the hottest months is particularly worthwhile, since demand for repairs spikes exactly when units are under the most strain.

Cost of HVAC Services

Pricing depends on the size of the unit, the type of system, and how extensive the fault is, but the table below gives a general guide to what to expect.

General diagnosis / call-out fee 1,000 – 2,500
Split unit AC servicing (per unit) 2,000 – 4,000
Gas refill (split unit, R410A/R32) 3,500 – 8,000
Compressor repair 8,000 – 20,000
Compressor replacement 25,000 – 60,000
PCB / control board repair 5,000 – 15,000
Fan motor replacement 4,000 – 10,000
Capacitor replacement 1,500 – 3,500
Drainage clearing / condensate fix 1,500 – 3,000

Ducted / central system installation 80,000 and above (site-dependent)
Maintenance contract (per unit, quarterly) 6,000 – 12,000 per year

Spare Parts Pricing

Genuine and OEM-compatible parts are used for all repairs, and prices vary by brand and unit capacity. Approximate part costs:

Spare Part Estimated Price (KES)
Compressor (1 – 1.5 HP) 18,000 – 35,000
Compressor (2 HP and above) 35,000 – 55,000
Fan motor 3,500 – 9,000
PCB control board 6,000 – 18,000
Capacitor 800 – 2,500
Refrigerant gas (per kg, R410A/R32) 2,500 – 4,000
Thermostat / sensor 1,200 – 3,500
Remote control unit 1,500 – 3,000
Drain pump 3,000 – 6,500
Copper piping (per metre) 800 – 1,800

Actual costs are confirmed on-site after inspection, since unit brand, refrigerant type, and accessibility all affect the final price.
