Service & Repair Tips To Keep Your AC Unit Running Smoothly

A condenser may not run due to many reasons. Some of the most common are blown fuses or tripped breakers that cut the power to the unit. High thermostat settings are another cause and reducing the temperature by five degrees can result in the condenser running again. 

A faulty motor or compressor may be the problem and needs to be looked at and replaced by a professional. An unbalanced distribution system results in uneven cooling and must be balanced to eliminate the problem.

When the unit is not cooling, check simple items first before calling an HVAC technician. Once again, a thermostat that is set too high might be the problem. Try lowering the temperature. 

A dirty condenser or evaporator may also be the cause. Clean the condenser coil and evaporator. Then clean and straighten the fins on the condenser. 

The condenser unit can become blocked. Remove all debris and cut down weeds and grass around the unit. Other causes for this problem include a faulty compressor, low refrigerant, or a refrigerant leak. These types of issues require an air conditioning service for evaluation and repair.

If the condensing unit is repeatedly kicking on and off, the condenser could be dirty or blocked. Remove anything blocking the unit and then clean the coil and fins. 

The evaporator could also be dirty. In many cases, the most common problem is the evaporator being dirty. Cleaning it will ensure that your AC is now able to cool the air in your house effectively.

The following list is some common problems that could be causing your AC unit to not be blowing cold and how to fix them.

5 Common Problems & Solutions For Your Heating & Air System

During the summer, the temperatures can get to their extremes and one will heavily rely on an air conditioner to make the house at least habitable. The worst thing that can happen on such days is finding out that your AC is not blowing cold air.

Common HVAC Problem & Solutions:

1. Clogged Air Filters

Many of us do not remember the last time we changed the AC’s filters. Taking too long before one changes them means that the existing ones have already been caked with dust and dirt from every dirt and contaminant particle in your home. 

When this happens, the airflow becomes obstructed and this means your home does not cool down and the coils may even freeze over. If this happens it results to:

  • our houses become warmer
  • The AC using more electricity which increases the energy bills.

The solution to this problem is that you are required to change the filters. There is a conventional policy that one needs to change the filters at least once a month to ensure that your AC blows cold air in your house.

2. Clogged Condensate Drain Lines

What an AC does is that it absorbs the moisture and heat from the air a room. What happens is that the humidity normally condensates on the evaporator coils. Additionally, the water then drips into a then gets siphoned out of your home through the condensate lines.

One thing for sure is that high levels of humidity usually cause mold growth and this also happens on the condensate lines. One can stop this from happening by having a regular AC maintenance done on your equipment. 

One can decide on cleaning the AC drain line by themselves by simply flushing them with distilled white vinegar and this will work if only the damage is done is not extensive. If the damage is extensive, one will require a vac that is wet and also an additional attachment that runs directly to the condensate from the vac.  

This will help you in cleaning the clogged condensate drain line and your AC will start blowing cold air and cooling your house as expected.

3. If the AC Unit is Too Small

For one to have an AC system that can effectively cool your home, it surely needs to have a specific amount of BTUs. BTU simply refers to the amount of heat an AC can eliminate from the air. The conventional measurement has a ratio in that for every ton of heat that has to be removed from the property, an AC unit will require to have 12,000 BTUs.

For one to understand the exact number of BTUs is needed to adequately cool your property, one has to consider the following:

  • The area space of your home.
  • The construction materials in your home
  • The type of insulation.

What you need to do is look at the AC’s BTU capacity on the label. You will find the label on the condenser unit. Having an air conditioner that has the right BTU means your home will cool as required as the equipment will be able to blow sufficient cold air to cool every corner of your house.

4. Leaking Refrigerant

The refrigerant is the gas that cools the air in your house. When your AC is working in a proper way, it does not require the help of a coolant. This said we know that wearing and tearing may cause pinholes in the unit and this results in a leakage of this gas.

One will certainly know that they have a refrigerant leak if they notice the following:

  • The AC produces a hissing sound.
  • If the home feels humid.
  • The vents start blowing warm air.
  • The AC using more power than before causing a rise in the utility bills.
  • If frost starts forming on the condenser unit.

One important thing to note is that breathing the refrigerant can cause breathing problems. Once you suspect that the refrigerant is leaking, contact the technicians immediately to help you fix this issue.

 Once the leaking refrigerant is replaced, your AC will be able to blow cold air once again and cool your home without a problem.

5. If Your Air Conditioner is Old 

Most quality air conditioners have a lifespan of 15 years. By the time these years lapse, one normally has repaired and serviced on several occasions. Extending the lifespan of your AC beyond its best years will require you constantly undertake additional repairs but it will break down, producing some funny noises and making your home smell in a weird way.

 It will also struggle with blowing cold air in your home. If this is the case, you need to buy a new air conditioner.

If the problem with your conditioner needs a professional to handle it, you will need to find the best HVAC contractor in your area. Being able to find the best HVAC contractor in your area should not be a challenge. You can simply ask for referrals from friends and family and you will be able to hire the best contractor who will fix any problem your AC equipment may be having.
