8 Big Mistakes You’re Making With Your Air Conditioner

All-time summer heat records keep buckling under the weight of rising global temps—a trend that hits home, literally and figuratively, when you receive your monthly air conditioning bill. Unfortunately, mistakes you’re making with your home A/C may be undercutting its efficiency, effectiveness, and safety, experts say.

“If you have a badly maintained system, it can become contaminated with microorganisms that may be harmful if inhaled,” says Mark Mendell, a staff scientist with the Lawrence Berkeley National Laboratory’s Indoor Environment Group. Mendell mentions asthma problems and allergies as some of those possible harms.

Here are eight of the most common mistakes people make when it comes to home A/C, and some simple adjustments that can save your lungs and wallet.

You Aren’t Changing or Cleaning Your A/C Filters

At a minimum, you should be changing the filter on your central A/C unit once every three months—and as often as once a month if your system is running all the time.

Neglect this chore, and a dirty filter can lead to poor air flow or freezing up of your unit’s evaporator coil. A filthy filter could add 5% to 15% to your A/C bill, and will shorten the lifespan of your whole system. Fortunately, replacement filters are not expensive! 

If you have ductless “split” A/C units, there should be a removable panel on your unit that will allow you to wipe off the filter with a rag—no replacement necessary.

You’re Not Having Your System Serviced Annually

An air conditioner’s filters, coils, and fins require regular maintenance for the unit to function effectively and efficiently throughout its years of service. Neglecting necessary maintenance ensures a steady decline in air conditioning performance while energy use steadily increases.

You Don’t Have a Programmable Thermostat

Maybe you’re one of those superhumans who always remembers to adjust the thermostat before leaving the house. But if you’re like the rest of us, a programmable thermostat can save you hundreds on your annual A/C bill by automatically raising the temp at those times of day when you’re at work or away from home.

You’re Setting Your Thermostat Too Low

Research shows the human body is capable of adapting to hot or cool temperatures pretty quickly—like within a week or two. When you consider you’ll cut up to 3% off your A/C bill for every degree you raise the temperature—not to mention the potential environmental benefits of lowering your A/C use—it’s worth sweating through that adjustment period and setting your thermostat somewhere in the high 20s (or higher if you can handle it).

You’re Not Taking Full Advantage of Fans

Any type of fan, but especially ceiling fans, can help keep cool air circulating throughout your home. That removes some of the burden from your AC system. Just be sure your ceiling fans are turning counterclockwise during the summer, which promotes greater air flow.

Your Thermostat and/or Vents Are Poorly Positioned

If the sun or a nearby lamp blasts your thermostat for big chunks of the day, that could throw off its readings and cause it to crank your A/C even though your place is pleasantly cool. Especially if you’re away during the day, you may not realise your system is working overtime due to a misplaced thermostat.

Blocking AC vents with furniture or curtains can also limit air circulation. Unless you spend a lot of time huddled under your sofa, you’ll want to be sure your A/C vents are unobstructed.

You’re Cooling Empty Rooms

If A/C vents are open in every room of your house, you’re chilling a lot of real estate that may not be in use on a day-to-day basis. Walk around and close those A/C vents that open onto unoccupied rooms. Also, closing closet doors ensures those spaces aren’t swallowing your cold air.

You Don’t Have Blinds Or Curtains

Bright sunlight is your A/C system’s nemesis. By closing blinds and sliding curtains to block the sun’s rays, you’ll also shield your space from the sun’s heat.

The Importance of Regular Pool Maintenance

Your swimming pool is a lot like your car. It requires a certain degree of maintenance in order to function properly. Just as you wouldn’t put off oil changes and tire rotations, it’s important to give your pool the same attention. Whether you handle it yourself or prefer to hire a pool maintenance company, here are a few of the ways you can keep your pool’s water crystal clear and bacteria free.

Managing the chemicals in your pool

Weekly, you should check the pH and chlorine levels. It’s important that your pH levels don’t dip below 7.0 or go above 7.4. Your chlorine should maintain a level of .6 to 1.5 ppm. You can use a digital meter or test strips to ensure that you get a proper reading of your water’s chemicals. Without weekly tests, your water may not be healthy to swim in.

Disinfecting the water

While water is fun to play in, it’s also a breeding ground for bacteria, algae, and fungi. Take the time each week to inspect your water and add the necessary disinfectant. While most people use chlorine to keep their pool clean, ozone therapy and UV lights are also great options.

Wipe down the exterior of the pool

The longer you go in between cleaning the tiles and the walkway, the more buildup there will be. Over time, this buildup can cause the tile to erode or to lose their luster. Be sure to use a cleaner that is safe for your water and that won’t break down the enamel of your tile.

Leak protection

The more frequently you inspect your pool, the easier it will be to spot a leak. The earlier you catch a leak, the less disastrous it is for your family and your property. Consider allowing your pool filter to run for 12 to 24 hours. Measure the amount of water in the pool before running your system and again afterwards. Refill your pool after running the filter and see if the water level changes. If it does, it’s time to call a professional to repair the leak quickly.

Filter cleaning

If you haven’t cleaned your pool’s filter in a while, you may be surprised at how dirty it is. The filter should be cleared out weekly to ensure that it works properly. Without it, you may find it harder to maintain your chemical levels or to keep the water clean.

Clean the pool liner

Your pool is full of dissolved soaps, hair spray, gel, and other products. They tend to leave a film on the liner of your pool that can be hard to clean. Using an appropriate cleaner take the time needed wipe things down frequently. This prevents buildup.

If you don’t have the time to dedicate to pool maintenance each week, hire a pool maintenance service. With experienced professionals, your pool will look beautiful all year around!

The Importance of Maintaining Your Air Conditioner

An air conditioner’s filters, coils, and fins require regular maintenance for the unit to function effectively and efficiently throughout its years of service. Neglecting necessary maintenance ensures a steady decline in air conditioning performance while energy use steadily increases. 

Air Conditioner Filters

The most important maintenance task that will ensure the efficiency of your air conditioner is to routinely replace or clean its filters. Clogged, dirty filters block normal airflow and reduce a system’s efficiency significantly. With normal airflow obstructed, air that bypasses the filter may carry dirt directly into the evaporator coil and impair the coil’s heat-absorbing capacity. Replacing a dirty, clogged filter with a clean one can lower your air conditioner’s energy consumption by 5% to 15%.

air condition service paphos

For central air conditioners, filters are generally located somewhere along the return duct’s length. Common filter locations are in walls, ceilings, furnaces, or in the air conditioner itself. Room air conditioners have a filter mounted in the grill that faces into the room.

Some types of filters are reusable; others must be replaced. They are available in a variety of types and efficiencies. Clean or replace your air conditioning system’s filter or filters every month or two during the cooling season. Filters may need more frequent attention if the air conditioner is in constant use, is subjected to dusty conditions, or you have fur-bearing pets in the house.

Air Conditioner Coils

air condition service paphos

The air conditioner’s evaporator coil and condenser coil collect dirt over their months and years of service. A clean filter prevents the evaporator coil from soiling quickly. In time, however, the evaporator coil will still collect dirt. This dirt reduces airflow and insulates the coil, reducing its ability to absorb heat. To avoid this problem, check your evaporator coil every year and clean it as necessary.

Outdoor condenser coils can also become very dirty if the outdoor environment is dusty or if there is foliage nearby. You can easily see the condenser coil and notice if dirt is collecting on its fins.

You should minimise dirt and debris near the condenser unit. Your dryer vents, falling leaves, and lawn mower are all potential sources of dirt and debris. Cleaning the area around the coil, removing any debris, and trimming foliage back at least 2 feet (0.6 meters) allow for adequate airflow around the condenser.

Preparing for Winter

In the winter, either cover your room air conditioner or remove and store it. Covering the outdoor unit of a central air conditioner will protect the unit from winter weather and debris.

Hiring a Professional

When your air conditioner needs its annual maintenance, hire a professional service technician. A well-trained technician will find and fix problems in your air conditioning system.

The technician should:

  • Check for correct amount of refrigerant
  • Test for refrigerant leaks using a leak detector
  • Capture any refrigerant that must be evacuated from the system, instead of illegally releasing it to the atmosphere
  • Check for and seal duct leakage in central systems
  • Measure airflow through the evaporator coil
  • Verify the correct electric control sequence and make sure that the heating system and cooling system cannot operate simultaneously
  • Inspect electric terminals, clean and tighten connections, and apply a non-conductive coating if necessary
  • Oil motors and check belts for tightness and wear
  • Check the accuracy of the thermostat.

Why Photovoltaics

Solar-generated electricity produces no greenhouse gases or emissions of any kind. Solar energy is a rapidly growing form of electricity generation. There are numerous advantages to using the sun to produce electricity

photovoltaic systems cyprus

For power generation through photovoltaic primarily only two inexhaustible raw materials are needed : sun and sand. The fuel—sunlight—cannot be embargoed. We are not expecting any conflicts about these resources . It promotes security and energy independence. Solar energy does not require import of fuels.
It has fewer environmental impacts than electricity generation with fossil fuel or nuclear power plants. No mining or transportation of fossil fuels are required to generate electricity with the sun. Photovoltaic systems produce electricity without pollution. When operating no waste products are generated.
PV is a source of peak power. Electricity has the biggest value when it is produced at the times of high demand. PV Power plants deliver electricity on daytime, when people work and factories and offices need electricity.

PV is a good combination with Wind Energy. Windpower plants produce most in winter times and in bad weather conditions. PV produces electricity in the summer, when wind plants are often not producing.
Because solar energy is available everywhere , this may make a very good contribution to economic development in less developed areas.

photovoltaic systems cyprus

Also for small businesses and individual consumers photovoltaics can represent an economic advantage. When producing electricity on their own roofs , the possibity of cost advantages compared to electricity purchases from the grid appear and make the usage of photovoltaic meaningful.
A few years ago, the electricity production had enjoyed a monopoly almost exclusively in the hands of corporations , who were also operators of transmission networks. Electricity was almost exclusively produced by large scale central power plants .
Today, 15-20% of the electricity is produced locally from renewable sources in a number of European countries. Solar energy contributes significantly in addition to wind energy.

PPR Pipes


Interplast PPR pipe and fittings are a hot and cold water supply system suitable for all potable water applications and heating systems. 

PPR pipes and fittings are considered to be the best carrier of potable water, using the revolutionary raw material of PPR-80 of Borouge brand. 

Image result for ppr pipes

PPR pipes are made with reference to the standard of DIN8077/8078 of Germany. 

There are three general types of polypropylene: homopolymer, random copolymer, and block copolymer.

The comonomer used is typically ethylene. Ethylene-propylene rubber or EPDM added to polypropylene homopolymer increases its low temperature impact strength. Randomly polymerized ethylene monomer added to polypropylene homopolymer decreases the polymer crystallinity and makes the polymer more transparent.
