While coastal areas present unique challenges, other geographic locations have their own impacts on AC units:

• Desert Regions: In desert regions with high temperatures and low humidity, AC units may face excessive heat stress. This can lead to accelerated wear and tear on components like compressors, necessitating more frequent maintenance;
• Inland Humidity: In some inland areas with high humidity, AC units may work harder to dehumidify the air, potentially reducing their lifespan. Proper maintenance and humidity control can help mitigate these effects.

Prolonging Your AC’s Life: Handy Hacks

Extend the life of your AC unit with these simple yet effective tips:

Regular Maintenance

One of the most effective ways to ensure your AC unit stands the test of time is through regular maintenance. Here’s a breakdown of what this entails:

• Annual Service Check-Ups: Schedule professional maintenance at least once a year. A certified HVAC technician will inspect your system, clean components, check for refrigerant leaks, and ensure everything is operating smoothly;
• Clean Condenser and Evaporator Coils: Over time, dirt and debris can accumulate on the coils, reducing efficiency and lifespan. Regular cleaning helps maintain optimal heat exchange and energy efficiency;
• Inspect Refrigerant Levels: Low refrigerant levels can lead to reduced cooling capacity and strain on the compressor. Technicians can identify and fix leaks while replenishing refrigerant levels;
• Tighten Electrical Connections: Loose electrical connections can lead to system failures and reduce the lifespan of AC components. Technicians will tighten these connections during maintenance.

Smart Thermostat Use

Smart thermostats are more than just convenient; they can also help prolong your AC’s life. Here’s how:

• Moderate Temperature Settings: Avoid setting your thermostat to extreme temperatures. Maintaining a moderate indoor temperature reduces the workload on your AC unit, preventing unnecessary wear and tear;
• Programmable Schedules: Utilize programmable thermostat features to adjust the temperature when you’re away from home. This ensures efficient cooling and less strain on the system;
• Zoning: If possible, create temperature zones in your home with the help of a smart thermostat. This allows you to cool specific areas as needed, reducing overall AC usage.

Clean and Replace Filters

Clean and properly functioning filters are essential for AC efficiency and longevity:

• Regular Filter Cleaning: Dust and debris can clog air filters, obstructing airflow and reducing cooling efficiency. Clean or replace your filters as recommended by the manufacturer or at least every 1-3 months;
• Improved Air Quality: Clean filters also contribute to better indoor air quality, preventing contaminants from circulating in your home.

Additional Tips

Consider these additional tips to further extend the life of your AC unit:

• Shade and Insulation: Provide shade for your outdoor AC unit to prevent overexposure to sunlight. Proper insulation in your home can also reduce the workload on your AC;

• Keep the Area Around the AC Unit Clean: Remove debris, leaves, and any obstructions around your outdoor unit to maintain proper airflow and cooling efficiency;
• Address Strange Noises or Issues Promptly: If you notice unusual sounds or performance issues with your AC, don’t delay in contacting a technician for a diagnosis and repair.

Household Discoveries: Little Known AC Longevity Tips

Sometimes, the best hacks are the simplest:

Optimize Airflow

One of the fundamental aspects of AC efficiency and longevity is optimizing airflow throughout your home. Here’s how to do it:

• Unobstructed Vents: Ensure that all vents and registers in your home are free from obstructions. Blocked vents can disrupt the balanced distribution of cool air, making your AC work harder to maintain comfort;
• Clean Vents and Ducts: Periodically clean the vents and ducts to remove dust and debris. Dirty ducts can reduce airflow, decreasing system efficiency and lifespan;
• Balanced Airflow: Make sure there’s a balanced airflow throughout your home. Closing off too many vents in unused rooms can create pressure imbalances that strain the AC system.

Use Fans

Ceiling fans and portable fans can be valuable allies in your quest to prolong your AC’s life. Here’s how fans can help:

• Air Circulation: Fans help circulate air in a room, distributing cool air more evenly and reducing hot spots. This allows your AC to operate more efficiently without overcooling specific areas;
• Perceived Cooling: Fans create a wind-chill effect that makes occupants feel cooler even at slightly higher temperatures. This enables you to set your thermostat a few degrees higher without sacrificing comfort;
• Reduced AC Usage: By using fans strategically, you can reduce your reliance on the AC, lowering its workload and extending its lifespan.

Insulate Your Home

A well-insulated home is not only energy-efficient but also kinder to your AC unit. Here’s why insulation matters:

• Reduced Heat Transfer: Proper insulation minimizes heat transfer between the interior and exterior of your home. This means your AC doesn’t have to work as hard to maintain a comfortable indoor temperature;
• Energy Savings: Insulated homes require less energy to cool, resulting in lower utility bills and reduced wear and tear on your AC unit;
• Year-Round Benefits: Effective insulation is not only beneficial in summer but also in winter, helping to maintain a consistent indoor temperature and reduce the strain on your HVAC system throughout the year.

Conclusion

The question of how long does an AC unit last depends on various factors, including maintenance, climate, and usage. By understanding the history, common mistakes, and effective maintenance hacks, you can ensure your AC unit serves you well for years to come. Remember, a well-maintained AC unit is not just about longevity; it’s about efficiency, cost-saving, and comfort. Keep your cool and make the most of your AC’s lifespan!

Since most private homes do not have access to centralized water supply and get water from the bowels of the earth, the most relevant for them are saving heat and electricity.

Heat costs are probably the biggest expense for a homeowner who lives in their cottage year-round.

Saving heat

Since most cottage settlements do not have a centralized heating system, saving heat for their inhabitants usually means saving on fuel. There are two components to these savings: improving the efficiency of converting a unit of fuel volume into degrees Celsius indoors, and reducing heat loss from the house (through walls, roofs and windows).

Improved fuel efficiency is achieved through the use of modern automated boilers, as well as their proper maintenance: regular cleaning of the boiler ensures that fuel consumption does not increase over time. In addition, efficient heating devices (convectors and radiators with the lowest thermal inertia) should be used in the house.

In addition to the boiler it is possible to use a geothermal heat pump, which heats the coolant for the heating system of the house by utilizing the heat of the earth. However, for the operation of the heat pump requires a small but uninterrupted power supply. If the possibility to organize it exists, then theoretically the heat pump can save up to 18% of the heating budget. However, we still recommend that you consult a specialist for calculations.

Reduction of heat losses is achieved, first of all, by insulating the walls and roof of a private house, i.e. by using modern insulation materials, the thickness of which is calculated in accordance with the climatic zone, and observing the technological conditions of their laying. Calculated work, however, as well as installation, of course, should be carried out by specialists, but the homeowner should know that energy saving should be thought about at the construction stage.

Finally, it is very important that the heating devices do not give away excessive heat to the premises, i.e. that there is no situation when the house is hot and you have to keep open the shutters. In fact, this means heating the street at your own expense and nullifying all measures to insulate the house.

To solve this problem, automatic radiator thermoregulators have been created, which are able to maintain the set temperature in the room without your participation. The principle of their operation is quite simple: when the air temperature in the room rises, the thermostat cuts off the water supply to the radiator. When the temperature cools down, the opposite is true. The temperature of the thermoregulator reaction is set by means of a rotating knob with a temperature scale. Thermoregulators can react to temperature changes as small as 1°C.

However, there is another characteristic of these devices, which is not always written on the packaging – the reaction time, which depends on the properties of the thermosensitive substance filling the sensor of the device. It is this parameter that should be the deciding factor when selecting a device.

Liquid thermostats have an average reaction time three times longer – enough to cause some discomfort. Finally, a solid-state thermostat will “swing” from 40 minutes to an hour, and sometimes even longer.

However, it is not possible to do without ventilation at all. However, some of the heat inevitably escapes from the house through open windows or shutters. The only way to save it is to use recuperated airers. According to the manufacturers of this equipment, as a result of ventilation loses about half of the heat received by the premises from the heating system. I.e. if the recovery efficiency is up to 76%, approximately 38% of the initially generated heat energy will be saved. Naturally, such a heat saving scheme will only work if there are radiator thermoregulators.

Saving electricity

The first thing that comes to mind is the admonition of the older generation to turn off the lights behind you, i.e. to use exactly as much electricity as you really need. But today there is another way not to spend extra watts – to use economical appliances, including energy-saving lamps.

Almost everyone has heard of the need to replace the usual incandescent bulbs with energy-saving bulbs (fluorescent, LED or halogen). And it must be said that it really makes sense. For example, a three-arm chandelier with fluorescent lamps, equivalent in brightness to incandescent lamps with a capacity of 60 W, for their lifetime (an average of 8 thousand hours) consumes almost 400 kWh less electricity than the same chandelier with incandescent lamps. The average annual savings from the LED lamp is about the same, but it pays for itself longer. However, and serves too.

In addition to the use of the “right” lighting fixtures, energy saving can be provided by a competent choice of household appliances. Since 1995, compliance with economical (in terms of electricity consumption) class “A” is reflected on the packaging or even the store price tag of washing machines, dishwashers, refrigerators and other large household appliances made in Europe and Russia. Obviously, specific values of energy consumption differ for different types of electrical appliances, but belonging to the “A” class (A+, A++) unambiguously informs us about consumption close to the minimum among those available on the market.

Producing electricity

Few homeowners think about the fact that they do not have to buy all their electricity from energy supply companies. Some of it can be obtained from alternative sources: for example, by recycling energy from the sun, wind or water.

Mini-electric power plants are just beginning to take over the private house building market. And since wind and hydro generators require special conditions for their operation (a river with a certain flow rate or a steady wind for more than half of the year), solar power plants are still the most popular. Although technically existing today solar cells provide quite low productivity, they are already quite capable of paying for themselves.

A home solar power station consists of several blocks: solar cells (panels), a block of batteries, which allows to store the energy accumulated during the daylight hours, as well as an inverter for converting direct current into alternating current. Given the low weight of the panels, they can be placed on the roofs or walls of buildings (on the south side).

The cost of an installation for converting solar energy into electricity is certainly high. And in certain conditions, for example, for a city apartment, it does not pay off. However, in a private home, an average photovoltaic plant, according to manufacturers, pays for itself in 7-8 years. In this case, the energy obtained from the sun, you can fully power, for example, the lighting of the house (when using energy-saving lamps) and part of household appliances: TV, refrigerator, laptop or water pump. By the way, it can also be used to power the heat pump discussed above.
