A Homeowner’s Guide to Air Conditioner Repairs

Published

on

It’s hot outside, and all you want to do is go inside your home and enjoy the cool breeze from your air conditioner. Unluckily, you walk in only to be greeted with the same sweltering conditions inside your home too. This is distressing.

Like any appliance, your AC needs repair and maintenance to provide optimum performance. Your air conditioner will break down f because of several causes, and some of these could be exact to the kind of AC you have. However, some air conditioner issues are universal.

An air conditioner is a sophisticated machine, and air conditioning repair can be a daunting job. While some repairs should be left to a qualified professional, there are quick and easy fixes for common air conditioner issues that you can try out before contacting an air conditioner repair expert.

Your Air Conditioner Isn’t Cooling Even Though It’s on

This is one of the most common AC problems, and it has several causes. Here is how you can fix this:

• Inspect for dirty air filters and clogged condensate drain. Replace or clean the filters and clear the condensate drain.

• Make sure there is sufficient refrigerant in the AC and inspect. There are no leaks before adding more refrigerant.

• Switch off the AC for some time in case the AC coil has frozen. The frozen coil is caused by dirty filters, insufficient refrigerant, or a faulty AC fan.

• If you own a central AC system, and some sections of your home are warmer than others, contact a professional and inquire about installing dampers in the unit. If you are in the Richardson area, and your ac isn’t working, check out ac repair in Richardson for a perfect solution.

Your Air Conditioner Won’t Turn On.

This could mean a faulty power supply or an issue with the thermostat.

To fix this, start by inspecting the thermostat. Ensure the thermostat is at a “cool” setting and reduce the temperature. If the AC isn’t turning on still, look for a blown a fuse or tripped wires and reset the power to fix it. You should also inspect your wiring to see if it’s affecting electricity flow.

If this doesn’t fix the issue, contact a professional to check if your air conditioner’s motor is faulty and if the wiring is still faultless.

No Air Flow from the Registers

How you handle this issue mainly depends on the type of cooling unit you have in your home. Start by inspecting whether the circuit breaker has fallen. If so, reset it after a few minutes.

If that didn’t work, it might be a sign that the blower belt needs replacing. Although this is a comparatively easy process, it has to be done by an expert.

If neither of the above two solutions works, it may be a sign the condensate drain reservoir may need emptying, or you have a faulty control board, wiring or thermostat.

Your AC Is Blowing Out Hot Air

There are several causes of this air conditioning problem. To check for and fix each of these, do the following:

• Replace or recalibrate the thermostat if it’s responsible for the issue-digital thermostats are a good selection in this case.

• Dirty air filters interfere with airflow, so inspect and, if need be, replace the air filter. The location of the air filter depends on the type of AC unit you have.

• Turn off your air conditioner and then smoothly brush debris off when the condenser or evaporator is blocked.

• With the electricity disconnected, clean the condenser coils and fins by smoothly spraying with clean water. Nevertheless, you need annual air conditioning maintenance to ensure the AC coils don’t get broken.

• Inspect the coolant; you will need to top it up if it’s insufficient.

The Air Conditioner Fan Is Not Working

When the AC fan is not working, your air conditioning will not be effective. Fix this by doing the following:

• Inspect if anything is preventing the system from getting power such as wiring issues and tripped switches.

• Reset the air conditioning unit by switching the reset button.

• After turning off and unplugging the system, remove anything obstructing the fan and spin the blades manually.

• If the system’s air filters are dirty, clean, or replace them.

When all these don’t fix the issue, it may be a sign your internal control board, control panel, or any other internal component has a problem. In most cases, the culprit is the capacitor that requires replacing.

Your AC is leaking or not regulating humidity.

Air conditioning systems produce condensation, which has to be drained to prevent the unit from leaking or more humidity in the air.

A broken condensate pump or blocked drain channels prevent your air conditioning unit from regulating humidity. Excess moisture in the air may cause discoloration in your carpets and walls. Here is how you can fix this:

• Disconnect the air conditioning unit from electricity and pass a rigid wire through the drain channels to unclog them

• Using an ideal bleach solution, clean the pump system

• Inspect for leaking pumps that may need fixing

• Make sure power connections to the pump are operational.

Also, inspect the safety switches and coolant pressure. If the coolant is leaking, the low-pressure switch may have been turned on.

Your AC Never Goes Off

An air conditioning unit should go off occasionally regardless of how hot it is. If your AC does not turn off, it could be a sign of issues with the fan. Clean the fan blades to ensure the fan is working at optimum speed.

Filthy air filters and condensers may also cause this issue. Cleaning these parts with professional products may fix the issue.

An AC that switches on and off regularly most likely has filthy or clogged evaporator or condenser. When the electricity is disconnected, clean the entire unit to remove debris.

AC is making strange noises.

Your air conditioning unit usually produces some noise, but it could be a sign of an air conditioning problem when you notice strange noises. Generally, the type of noise you hear gives a hint of the nature of the issue.

• Squealing noises are a sign of belt issues and can be fixed by replacing the belt or correctly aligning it.

• Grinding sounds are usually signs of motor bearing problems: ensure expert oil the AC unit annually.

• Rattling noises are an indication of bent, loose, or dirt fan blades or coil fins. Use a vacuum cleaner to clean the blades, try bending them back in place and make sure screws are correctly tightened.

• Pinging sounds may indicate loose fold of metal in the duct system.

Air conditioning repair may be nerve-wracking. Before fixing your AC unit on your own, make sure you don’t do anything to put you at risk of an electric shock or void your unit’s warranty. For most AC repairs, you should contact a professional.

First-of-Its-Kind Blueprint for Data Policy Adopted by City of Helsinki

Published

on

The World Economic Forum today released Empowered Data Societies: A Human-centric Approach to Data Relationships. The framework put forth in the white paper ensures that data is used in responsible and innovative ways to create progress while respecting, valuing and empowering people and communities.

As part of a year-long partnership with the City of Helsinki, the World Economic Forum convened a global community of technologists, anthropologists and policy and data experts to develop a new way to create data policy oriented around the values, needs and expectations of people.

By leading with the interests of those generating data or most impacted by resulting insights, this approach mitigates the trade-offs between innovation and privacy.

The Forum worked with a dedicated team of data practitioners and policy-makers with the City of Helsinki to apply this new methodology to develop a dedicated anonymization pipeline for complex personal data that will allow for maximal data utilisation anchored in respect for individuals and their privacy. New pathways, processes and tools were also created to document a best practice blueprint for human-centric proactive services, which Helsinki will open-source for future expanded use and improvement.

“Throughout this year-long partnership we were motivated by the principle that human-centricity is neither a ‘nice to have’ nor a ‘deluxe’ approach to data. Human-centricity can and should be the foundation upon which to build empowered data societies. With the release of this paper, we aim to share frameworks, insights and best practices so policy-makers around the world can adopt and build systems that use data in responsible and innovative ways to create progress that legitimately serves people and communities,” said Sheila Warren, Deputy Head of the Centre for the Fourth Industrial Revolution Network, World Economic Forum.

The City of Helsinki created several tools to enable efficient utilization of extremely sensitive data. The main principle behind the blueprint is that the storage, anonymization and processing of data are separated and that different individuals perform each task.

Forging a way to create entirely new data analytics capabilities for Helsinki has resulted in a new technical environment for treating sensitive personal data with the highest ethical, data protection and cybersecurity standards. This environment will be used as the city continues accelerating its use of data to provide more personalized and timely services for its residents and visitors.

“Helsinki’s commitment to serving its citizens requires going beyond traditional service provision and tapping into the full potential of data to deliver the best quality services in the most efficient way possible. Using data responsibly requires the development and implementation of new practices that are human-centric – those that assure citizens’ interests are respected and prioritized at all times, empower citizens to improve their own lives through data, and increase participation in the overall ecosystem by building trustworthy data relationships,” said Jan Vapaavuori, Urban Activist and Mayor of Helsinki (2017-2021).

Much of the data needed to tackle the world’s most pressing challenges is siloed in public and private sources. Even for social good, the various regulatory, commercial and social risks prevent data sharing. The Shaping the Future of Technology Governance: Data Policy Platform works with partners from all sectors, regions and industries to develop agile and innovative approaches to accelerate the responsible use of data and empower stakeholders across the entire data ecosystem.

Digital billboards bring real-time air pollution data to Nairobi

Published

on

Image source: UN Environment

Digital billboards around the Kenyan capital today started to live stream Nairobi’s real-time air pollution in an effort to increase air quality awareness among the city’s 4.7 million inhabitants.

The initiative – by the UN Environment Programme (UNEP), in collaboration with IQAir, a Swiss air quality technology company, Safaricom, a telecommunications provider in Kenya, Alpha and Jam Ltd and Metropolitan Star Lite Ltd,  Out Of Home (OOH) media – provides real-time air quality information for some of the most harmful type of air pollution, fine airborne particles, known as PM2.5. The pilot aims to engage the public by streaming real-time air pollution information to digital billboards at 4 critical locations in the city: Moi Avenue, University Way, Mbagathi Way and Jomo Kenyatta International Airport.

PM2.5causes serious health issues, including asthma, lung cancer, and heart disease. Exposure to PM2.5has also been associated with low birth weight, increased acute respiratory infections, and stroke.

“Real time air quality monitoring will help us with the issuance of health advisories as well as for formulation of smart traffic controls that minimize congestion,” said Lawrence Mwangi, Assistant Director of Environment in charge of pollution control at the Nairobi County Government. “Dynamic advisories demonstrated through this collaboration will help people limit their exposure to harmful pollutants.”

Around 3 billion people cook and heat their homes using open fires and simple stoves burning biomass (wood, animal dung and crop waste) and coal. More than 50% of premature deaths due to pneumonia among children under 5 are caused by the particulate matter (soot) inhaled from household air pollution.  Outdoor air pollution in both cities and rural areas was estimated to cause 3 million premature deaths worldwide in 2012 with 88% of those premature deaths occurring in low- and middle-income countries.

Policies and investments supporting cleaner transport, energy-efficient housing, power generation, industry and better municipal waste management would reduce key sources of urban outdoor air pollution.  Most residents of the city do not have access to real-time air quality data and consequently, are often unaware of the harmful levels of air they breathe.

“Action on air pollution, which is responsible for millions of premature deaths a year, is critical – efforts should focus on high-risk communities, such as people living in informal urban settlements,” said Inger Andersen, Executive Director of UNEP. “Innovations to reach and engage the local community and decision-makers alike, can only elevate the understanding of the impacts of air quality and help create an enabling environment improve human and ecosystem health.”

“We recognize that some of the world’s most vulnerable communities are disproportionately affected by poor air quality,” said IQAir CEO Frank Hammes.  “Through our partnership with UNEP, we are able to leverage real-time air quality monitoring data, machine learning and data visualization to help identify those that are most affected by global air pollution. The real-time visibility of the impact of air pollution on mankind, combined with the outreach and support that the UNEP offers, can help governments and communities around the world take actions that lead to cleaner, healthier air.”

The Nairobi air quality awareness demonstration project is the result of a unique collaboration between the UN, the private sector, academia, non-governmental and local governmental organizations and is expected to accelerate efforts to change how transport, waste management and other services are managed in cities so that air pollution from these activities is significantly reduced, if not eliminated.

“This partnership lies very much at the heart of our sustainability agenda that seeks to address environmental issues such as air pollution which remains a major challenge especially in urban centres. We intend to use our digital platforms and expansive network infrastructure to support the air quality monitoring project to expand across more urban areas in Kenya. We will also foster partnerships with other stakeholders including regulators, relevant ministries and private organizations to help build a compressive and sustainable air quality monitoring system in the long run”, said Peter Ndegwa, CEO, Safaricom.

The demonstration project comes as the world celebrates the 2nd International Day for Clean Air and blue skies on 7 September, this year held under the theme, Healthy Air, Healthy Planet. The Day calls for increased international cooperation at the global, regional and sub-regional levels. It provides a platform for strengthening global solidarity as well as political momentum for action against air pollution and climate change, including the increased collection of air quality data, carrying out joint research, developing new technologies and sharing best practices.
