Have you ever woken up in the middle of a winter night, shivering under the blankets and able to see your breath? Or have you ever watched the thermostat creep into the upper 80s during a record-setting heat wave, realizing you haven't heard the air conditioner kick on? If so, your heating or cooling system was on the fritz—and (of course), it happened at the worst possible time.
These systems not only fail when you need them the most, but also during the hardest time of the year to get a heating, ventilation and air-conditioning (HVAC) contractor to come by for repairs. Naturally, technicians are at their busiest when these systems are busiest. So, unless you have a relative in the business, the best way to ensure your heating and cooling systems keep working is to maintain them properly.
To guard against a future breakdown, have a professional perform periodic maintenance on the systems before the peak seasons begin. Have the heating system serviced in late summer or early fall, and keep in mind that priority scheduling for repeat customers may begin mid-summer. For a central air-conditioning system, arrange to have a pro check it out in the early spring, after temperatures have reached 65° F, depending on when it starts getting hot in your region.
A typical maintenance call will involve tightening electrical connections, checking the condition of hoses and belts, lubricating all moving parts, and making sure the controls work properly.
For cooling components, the contractor will clean the evaporator coils that remove the heat from the air in your home, as well as the condenser coils that release the collected heat to the outside air. Your tech will also check the fan components, make sure the refrigerant level in the system is correct, inspect ductwork and gas lines, and check for leaks.
For heating systems, technicians typically check fuel connections, change the filters, and inspect the system's combustion and heat exchangers.
What You Can Do To Keep Your HVAC System Operating!
Here are a few maintenance tasks you can perform yourself:
Repair Vs. Replace
If your HVAC system does break down, you will be faced with the decision of whether to repair or replace it. Repairs are less expensive, but there are a number of reasons to consider replacing the entire unit.
Winterization is the process of preparing a home for the harsh conditions of winter. It is usually performed in the fall before snow and excessive cold have arrived. Winterization protects against damage due to bursting water pipes, and from heat loss due to openings in the building envelope. Inspectors should know how winterization works and be able to pass this information on to their clients
Even during very small ruptures or ruptures that are stopped quickly, water leakage can result in mold and property damage. Broken water pipes can be costly to repair.
Leaks In The Building Envelope
Leaky window frames, door frames, and electrical outlets can allow warm air to escape into the outdoors.
Cooling System Winterizing
Chimneys & Fireplaces Winterizing
Adequate winterization is especially crucial for homes that are left unoccupied during the winter. This sometimes happens when homeowners who own multiple properties leave one home vacant for months at a time while they occupy their summer homes. Foreclosed homes are sometimes left unoccupied, as well. The heat may be shut off in vacant homes in order to save money. Such homes must be winterized in order to prevent catastrophic building damage.
In addition to the information above, InterNACHI advises the following measures to prepare an unoccupied home for the winter:
In summary, home winterization is a collection of preventative measures designed to protect homes against damage caused by cold temperatures. These measures should be performed in the fall, before it gets cold enough for damage to occur. Indoor plumbing is probably the most critical area to consider when preparing a home for winter, although other systems should not be ignored.
