De-greaser and spraying tools are mandatory to eliminate the stubborn stains and grease from your AC. These tools are satisfactory for basic cleaning purposes.

Other Tools For Air Conditioning Service

You also need a set of screwdrivers to remove the panel of your air conditioner. If your air conditioning unit uses disposable air filters, make sure to carry extra ones.

These tools and accessories are usually enough for a DIY air conditioning repair job. If your AC has mold growth, you not only have to remove it but use an anti-mold growth spray to prevent further growing for years.

It is important to check your air conditioner each year, usually before summers to make certain that they will function smoothly when you need them the most.

People leave their air conditioners unattended in fall and spring, only to find a lot of unexpected troubles in summer and winter. By cleaning the AC and removing debris, particles and animal waste etc from your air conditioning unit before start using them, you not only improve the air quality inside your home but this method also helps you to improve the energy efficiency.

Air Conditioning Repair And Replacement – How To Determine The Cooling Capacity

Doing a home inspection that involves calculations of heat gain appropriate for cooling capacity may not be possible. But an external inspection on the same will give you an idea. For example, the appropriate calculation is 36,000 BTU. This calculation will not be possible to do at home, but an external inspection will not only give you this information, you can also know the absence and presence of cooling sources of the building.

Cooling capacity requirement for your air conditioning repair and replacement:


  • For cooler climates as in the Northeastern United States the capacity is one ton/400 sq .ft. for commercial and one ton/500 to 1000 sq .ft. for Residential units.

  • For Space Pak Systems, one ton/400 to 800 sq .ft. is required.

  • A 3000 sq .ft. house needs a 5-ton unit. And in case of supply outlet count – An estimated 100 cfm @ 10 outlets = 1,000 cfm . Which means 2.5 tons is needed.

  • Try to stay away from BTUs of capacity than you actually need

An oversized A/C will have too much capacity and will rapidly drop the indoor temperature to such extent that the cooling cycle will be very short to allow sufficient decrease in the humidity level. It is true that indoor comfort is a balance between temperature and humidity.

Moreover, when the A/C will be turning on and off more frequently, the comfort level will decrease and this will also be hard on the equipment. Hence, it reduces its life span.

Turning the motor on and off frequently can damage the equipment and will result in expensive air conditioning repair and replacement.

If you notice that the on and off is unusually short, or the humidity level drops, you need to go for an air conditioning repair.

Air Conditioning Repair – Compressor Installation Errors You Should Stay Away From

Many air conditioning repair services are not very open hearted in pointing the mistakes in a cumbersome installation because they are worried that it can cost their business. It is important to make sure that your AC repair service has installed the compressor professionally. This is very important to keep your air conditioning repair costs within the budget.

Air Compressor Installation And Airflow

It is important that an air compressor installed outside should only have minimum clearance to ensure adequate air flow. There should be ample space between the compressor and wall for allowing free passage of air. This is very important for the condenser coils to be cooled effectively.

Common Mistakes You Should Address During Air Conditioning Repair

Compressors installed on first floor and above are usually mounted too close to the wall and multiple units are placed adjacently. This is not a good setup for better efficiency from your air conditioner. If your wall does not have ample space for multiple compressors, consider air conditioning units that come with multiple ACs on a single compressor.

Or else, be prepared to spend money on your air conditioner compressor from time to time as its longevity will be affected.

Overgrown plants are great obstructions to the free flow of air to a compressor. This usually goes unnoticed but can cost a premium as your compressor is one last for more than a few years.

When you’re hiring an air conditioning repair professional, make sure to get your compressor installed without any obstructions as free air flow will prevent the units from excessively heating up.

Cut plants from time to time and remove nests of animals that are usually made behind the compressors. From time to time, soil will accumulate along with debris around the compressor, and this should be removed in every summer.

Air Conditioning Repair Guide – Reasons Your Air Conditioning Unit Is Not Operating

Realizing your AC is not working on a hot summer day can be quiet frustrating. However, you can do your best to help the issue before you call in for professional HVAC help. There are 4 main things that you need to check:

  • Electrical power – the electric power may be set off.
  • Controls – the controls of the AC unit may be improperly set.
  • Thermostat – check if the thermostat has been set on and to cooling positions. If you recently changed the thermostat, make sure the wires are hooked up correctly.
  • Switches – check for any other switches relating to the AC functioning. There may be some hidden switches like the Condensate Tray’s Float switch or the reset switch on the bower motor.

If you notice your AC is not producing enough cool air like before, check the duct system or the compressor or condenser outside. Sometimes, the condenser can automatically turn off and on every few seconds which makes it not produce enough cooling air. The cycle should be a minimum of 10 minutes to produce enough cooling air. You can check the condenser or the compressor unit to help rectify any fan or motor problems.

If you notice the compressor making strange noises during start up, you surmise that there is an operation problem and it’s time to call an air conditioning repair professional. For next time, remember that regular maintenance and cleaning can help you avoid such major issues reducing the cost of your air conditioning repair.

Another problem you may uncover while you do an air conditioning repair may be defects in the evaporator coil. You may notice a blocked coil, dirt or frost on the coil that hampers its functioning. Improper cooling or evaporator placement or improper size of the evaporator coil may cause serious malfunctions.

The above air conditioning repair measures will surely help you identify any serious issues with your air conditioning, and if you feel the scope of work is outside of your comfort zone, call a licensed and experienced HVAC company.

Air Conditioning Repair – It’s Cooling, but Not Enough

What should you do when your air conditioning is working, but it isn’t providing enough cool air? Sometimes an air conditioner unit is still creating cool air, but it isn’t enough to cool your entire home. With these tips and tricks, we’ll help you diagnose the problem and determine whether or not you can fix it on your own.

The Thermostat May Be Too High

This is an obvious solution, but one you may have missed. Before assuming that your air conditioner must be broken and needs repair, check the thermostat settings. If the thermostat is set too high, lower it about five degrees. Let it run for an hour or two and then check the temperature in your home.

Dirt

Dirt is one of the largest problems for an inadequate cooling system in your air conditioner unit. Check the filter. If it’s dirty, clean it or replace it. Check the coils. If they are dirty, clean them or replace them. Cleaning your air conditioner may be the only form of air conditioning repair that you need.

Blockage

Is your condenser blocked from the outside? If it is, remove the blockage and then check the status of your air conditioning unit. Another problem can be actual pieces of debris in the unit itself. These can create blockages that cause your air conditioner to malfunction. Check between wires and inside of the unit for any possible blockages caused by random objects.

If You Can’t Find Anything

…then it’s time to take it to a professional air conditioning repair specialist. These specialists are trained to find the more complex problems in air conditioner units. The most important step when turning to a professional is to find a service provider that you trust and that offers fair prices as well as a satisfaction guarantee.

Air Conditioning Repair Guide – Know Your Refrigerants

For those who like DIY air conditioning repair, or are hiring a professional to get the job done, should know about refrigerants as they are critical components of your AC.

The federal government has implemented a ban on CFC based refrigerants that are harmful to the ozone layer. Most modern day refrigerants are not harmful to ozone as they do not use CFC as an ingredient.

Ammonia

Ammonia is toxic but it’s lighter than air, thus, it never stays on the floor area, even if there is a leak. This is one of the oldest refrigerants known to man but is usually used in large commercial sector.

Sulfur Dioxide and Hydrocarbons

Sulfur Dioxide and hydrocarbons are also used in the air-conditioning system but are not very popular today.

Freon

Freon is a commonly used refrigerant in HVAC systems and other home AC units.

There are many other refrigerants, including water, used in air-conditioning systems, but some of them are banned due to the CFC content in it.

Although the government banned using Ozone-unfriendly refrigerants in newly installed air-conditioning units, there is no problem for using them in air conditioning repair or service on an older AC.

For instance, you can change the ozone unfriendly refrigerants in an existing unit with the same refrigerant, but it is not permitted with a brand-new unit.

Commercial Aspects Of Air Conditioning Service And Refrigerants

If you have a very old air-conditioning unit that uses refrigerants like R-22, which is ozone unfriendly, it is important to note that your air conditioning repair sessions are going to cost you a lot more in the future as a government imposed restriction reduced their production, and the price is also likely to get high.

If your unit is pretty old and requires a major overhaul, consider changing the unit with a brand-new one to avoid expensive air conditioning repair in future.
