The installation of air conditioning at home and the filling of air-conditioning holes is a step that cannot be taken. But the answer to the question of how much to put in the air conditioner hole is like a blind box -- what difference does it make when the master asks for $50 or $200? Today, from wall material, floor height to seasonal factors, hand-held hands teach you to read the sub-rule behind the price, to spend a little money on the big deal
First, look at the mass of the wall. Different hardness corresponds to different prices
The harder the wall, the more difficult it is to pierce it, the higher the price naturally. Common wall types and price ranges are as follows:
1. Brick walls (most common, lowest price)
- average brick wall at a rate of $50 per person
Such walls are low in hardness and can be handled with ordinary impact drills, suitable for families with limited budgets。
- brick wall (>30cm thick): $50-80/ individual
The increase in thickness and the high wear and tear of the drill leads to the possibility that the master will charge a “material consumption fee”。
- the real case: ms. Chengdu li's old brick wall hit the air conditioner hole, the master offered $40 and it was done in 10 minutes without extra charges。
2. Concrete walls (high hard, medium price)
- normal concrete walls: 60-100 yuan/s
Water drills (drilling rigs with water pipes) are required to penetrate, equipment costs are high and prices increase naturally。
- steel and concrete walls (with steel): $100-150/ individual
Steel bars the drill, and masters may need to change harder alloy drills, double the time and double the cost。
- pipes: if the master doesn't say the walls have steel bars in advance, work on them, and we'll raise the price
3. Glass walls (special mass, large price fluctuations)
- normal windows: $50-80/ individual
Carefully operating with a glass drill, the technology is high and the master may charge a “technical fee”。
- steeled glass: $100-200/ individual
The broken glass was broken with a special tool and the price doubled。
- master reminds him to make sure he has insurance before the steel glass is pierced
Brick walls (hard surface, soft interior)
- general tile walls: 40-60 dollars/piece
The tiles are hard-earned and prone to collapse when pierced, and the master may charge “repair costs” and suggest early communication。
- antique brick wall: 60-80 yuan/s
The antiquated brick surfaces are condensed and the drills are easily smooth, time-consuming and more expensive。
High-level floor directly affects the price. High-level operating costs are huge
The higher the floor, the greater the security risk, the master will charge “high-altitude operating fees”. Specific criteria are as follows:
1. Lower level (1-3 floor)
- cost: 0-30 per person
The ground is operational, no safety rope, the lowest price。
- true case: mr. Guangzhou's house was pierced on the 2nd floor, the master confiscated high air fare and only received $50 in base fee。
2. Middle level (4-10 floor)
- cost: $50-100 per person
There is a need for safety ropes and the master may charge a fee on the floor (e. G. $50 on the fourth floor plus $10 per floor)。
- pipes: if master says, "ucp 100 above the fourth floor", the rate is set for you。
3. Upper level (11th floor and above)
- cost: $100-200 per person
Safety ropes, anti-crash devices, helmets, and limited operating hours (e. G. Unworkable in the middle of a storm) are the highest prices。
- data comparison: an official offer for a brand: $200 on the 11-20 floor and $300 on the 21st floor or above is more expensive than the guerrillas but safer。
Three, these hidden factors will raise prices! Don't wait till you're done
Apart from walls and floors, there are “hidden costs” that affect prices:
1. Aperture size (larger and more expensive)
- general aperture (63mm): $50-80/ individual
It is suitable for hang-up air conditioners, most of which are adequate。
- large aperture (over 75 mm): $100-150/ individual
A cabinet or central air conditioner requires larger holes, with higher drilling and labour costs。
2. Seasonal factors (30 per cent increase in prices during the season)
- light season (spring and fall): lowest price, wrong peak hole。
- swing season (summer winter): the supply of teachers is not sufficient and prices may rise by 30 per cent. For example, the summer perforation fee in shanghai increased from $80 to $120。
Additional services (cleaning/repair/waterproofing)
- dust cleaning: 20-50 yuan/minus
Water drills generate mud and the walls are covered with dirty marks。
- refurbishment of walls: $50-100/site
Repairs are required if the tiles are broken or the walls are bouqueted during the piercing。
- waterproofing 30-80 yuan per hole
Waterproofing must be done for exterior wall holes, otherwise rain pours into the walls。
Selection of 5 pit avoidance techniques for air-conditioning hole services
Questions were raised as to whether a “sipple price” or a “sub-fee” should be included
- the price: consists of punches, cleaning, waterproofing, suitable for lazy people。
- sub-fees: additional costs may be hidden, such as “faulting $50 + $30 clean-up + $20 waterproofing = $100”。
- the right approach: to have the master report the total price and then compare it with more than three households, avoiding being “attractive at low prices and at high prices”。
2. Inspection tools for specialization (water drills vs. Impact drills)
- drilling: cooling with a pipe, suitable for concrete walls, clean holes and dust。
- impact drills: fit for brick walls, but concrete walls are easy to drill and generate large amounts of dust。
- pipe-shield: if the master hit the concrete wall with a shock drill, it could be a half-priced tool
3. Confirmation of the inclusion of waterproofing
- the outer wall: the water must be protected or the consequences of the leak must be self-sufficient。
- internal wall holes: can do nothing but recommend it to prevent the infiltration of condensed water。
- the real case: ms. Hangzhou zhao did not do waterproofing, which resulted in a bad rainy season, with $300 worth of repairing, more expensive than punching。
4. Conclusion of simple agreements with clear responsibilities
- the content of the agreement:
- pointing position and aperture size
- what services are included in the cost (e. G. Cleaning, waterproofing)
- forms of compensation for damage (e. G. Broken walls, broken glass)。
- pipepoints: verbal promises are useless and must be written in plain and black, so as to avoid pandering。
5. Prioritization of air conditioner brand co-workers
- advantage:
- prices are transparent and do not increase prices at random
- tool specialization, technical security
- problems can be complained to by the brand。
- price comparisons: co-editor of the gry, american and other brands, who usually cost 20 per cent more for perforation than the guerrillas, saves their energy。
V. Common answer: have you ever stepped on these pits
1. Do you have to hire a professional teacher for air conditioning
It's easy to hit a hole in itself, break a wall or even hit a wire or a hose。
What if the back of the hole is dirty
- solutions:
- cleaning up with vacuum cleaners (advanced in advance)
- he rubs himself with wet cloths, stubborn stains with little soda。
3. What if you hit a steel band when you hit a hole
- temporary solution: a different position to avoid steel bars
- long-term hazards: if steel bars are broken, they may affect the wall structure, and it is recommended that they be dealt with by the property industry or by a specialized firm of reinforcement。
4. When air conditioning is installed, are the costs of perforation and installation separate
Most brand installation costs include basic services (e. G., hanger, take-over) but additional services such as piercing, cavity, etc. Are charged separately。
5. The old house is remodeled. Is the old hole still working
- disaggregation:
- acoustics appropriate and unblocked: available, but for sealing
- too small or blocked an aperture: it must be hit again, otherwise the effect of air conditioning is affected。
Concluding remarks
How much for air conditioning? The answer depends on the mass of the wall, the height of the floor, seasonal factors and additional services. The lower floors of the brick wall are the cheapest (30-50 dollars) and the upper layers of concrete with steel (100-200 dollars). Remember: don't look at low prices, ask whether it includes clean-up, waterproofing, preference for brand co-workers, and clear responsibilities for entering into agreements. It'll cost you a few dozen dollars to buy peace. Let's figure this out before the next air conditioner
What, you still use your own money for the renovation? The renovations were phased, with an ultra-low annual interest rate of 3. 55 per cent and a maximum of $1 million. I'll apply for a discount immediately
