What is different about aircon work in Pa Phai
Pa Phai lies east of the Mae Jo area. Most of it is flat land, with some hills covered in open forest. Some homes on the west side fall within Mae Jo Town Municipality, while further in are villages that mainly grow rice and tend orchards. The sub-district has the Huai Jo Reservoir at Ban Pong, the Huai Salaeng Reservoir and Wat Doi Thaen Phra Pha Luang on a hill, as well as several garden cafés.
Hills and open forest take smoke haze directly in the dry season
Pa Phai is one of the sub-districts where staff patrol for forest fires in the dry season, so homes on the hillside take in more smoke and ash at that time than other areas, and filters clog faster than usual. I recommend a full clean before the smoke season, and during the season remove and wash the filters yourself every two to three weeks.
Homes in orchards and next to rice fields: outdoor units collect leaves and soil dust
Homes in orchards or next to rice fields often have the outdoor unit outside under trees. Dry leaves pack into the fins and grille, and during field preparation soil dust adds to it. Both reduce the unit's ability to dissipate heat. I open up and check the outdoor unit every time I come to clean, and let you know if the unit's position should be changed.
Rental rooms on the Mae Jo side can be cleaned together
The west side of the sub-district, within Mae Jo Town Municipality, has a number of rental rooms and apartments. If a building owner books three or more units, the price is 450 THB per unit. Let me know the number of rooms and when they are empty, and I will schedule the work back-to-back in one round.
How I work here
I am based in San Kamphaeng and work in Pa Phai, San Sai regularly. Landmarks in this area: Huai Jo Reservoir · Wat Doi Thaen Phra Pha Luang · San Sai–Pa Muead Road
I always give the price before I start, check the unit in front of you, explain the real cause, and do not top up refrigerant unless it is actually low, because overcharging uses more power and shortens the compressor's life.
For every clean I lay a two-layer cover sheet first and leave the area tidy before handing over. Every unit gets a disinfectant spray, with a 30-day warranty against dripping (60 days for the full strip-down clean). If it drips in that time, I come back and fix it free. Repairs carry a 30-day warranty.

Common questions about aircon service in Pa Phai
I run a garden café in Pa Phai. How often should the café's air conditioning be cleaned?
More often than a home, because the unit runs continuously during opening hours, the frequently opened door lets outside dust reach the filters easily, and the outdoor unit in the garden also collects leaves. I check both sides and tell you the right interval, and I can schedule the work at a time that doesn't disrupt your business.
I live in Pa Phai. Do I need to book in advance?
Booking two to three days ahead gives you the widest choice of dates and times. Prices in Pa Phai are the same as everywhere in the service area, with no extra travel fee.
How soon can you come to Pa Phai?
Usually within 24 hours, and the same day if I have a slot free. The exception is February to April, when the whole province is busy, so it is best to check a slot in advance by phone or LINE.
Is there a travel fee in Pa Phai?
No. Pa Phai, San Sai is inside my normal service area, and the price I quote is what you pay.
Do you clean aircon in condos and dorms here?
Yes: houses, condos, dorms, cafés, restaurants and offices. There is a lower rate when several units are cleaned together.
