Prices for the smallest system start at around $5000. The ducting cost depends on the number of rooms where you must have ducting and the house's size. Installation depends on an existing structure, how much work is involved in ducting, and so on. Another factor is the control type. Simple thermostat controls are not expensive. However, if you opt for smart home automation as most people do these days, expect to pay a premium for such intelligent automation. Repair services where costs vary between $50 to $120 per hour depending on the nature of work.
If you have a permanent home and do not plan to move we recommend a central packaged HVAC setup. It will probably reside in your basement, and hot/cold air is delivered throughout the house or only to specific rooms through ducts. Window or split systems are ideal if you wish to save on energy costs and only cool down occupied rooms. The drawback is that if you have many rooms, then you have to install individual systems. The good thing is you use it only when and where required and these systems can be uninstalled and transported with ease which is good if you live in rented premises, but they can get noisy, whereas centralized units restrict noise to the basement.
Many things can go wrong with an air conditioning unit, the thermostat can stop working correctly, or there could be a gas leakage, reduced pressure and gas will reduce cooling no matter how long you keep the system on. If gas has leaked out it shouldn't cost much to get it refilled, the presence of dust can also block airflow across the cooling unit and a third possible reason is compressor parts that often worn out, leading to insufficient gas compression. In this case, you should use Talk To Bruno to contact a nearby technician to examine your system and recommend repairs.
We recommend that you consult with service technicians on our site and schedule periodic maintenance contracts. Be clear with the technician what it entails as some of them will charge maintenance fees to come and inspect the unit at your place, if repairs are needed, then you pay for parts and labor, if you have a new system, then we suggest routine maintenance every 3 months. It is good for older systems to check the unit before summer and winter and get repairs done to the unit.
There are impending trouble indicators, and you can prevent major breakdown by learning to recognize such signs. Call in a service tech immediately you notice any of these signs in your equipment. If the equipment makes higher than normal noise at startup and makes noise when you switch it off, like a rattling noise, it needs to be checked.If airflow speed is reduced, it could point to the need for lubrication of fan bearings or a possible jam or loss of coil winding strength. If the unit stays switched off or on, then there could be something wrong with the thermostat, particularly if the cut-off or cut in does not occur at the set temperature range. If heating or cooling reduces progressively over time and the compressor stays on, it is a sign of trouble and requires immediate attention.
