How Does an AC Unit work?
A fan removes warm air from the room and blows it across the evaporator coils in the AC unit. The evaporator coil contains refrigerant in a cold liquid state. It absorbs the heat from the air, and the refrigerant turns into a warm gas. The air is now cooled and is blown back into the room.
The refrigerant gas is now pumped through a compressor and is squashed from low pressure to a high-pressure gas. It now passes through a condenser and is converted back into its original liquid state.
The condenser is normally situated outside the house and is surrounded by cooling fins, these help to radiate the heat away to the outside air. The liquid refrigerant is pumped back into evaporator coils and the cycle repeats itself.
Warning Signs That You Need a Heating and AC repair
Having your HVAC unit regularly serviced by one of our highly trained technicians is strongly recommended by Minuteman. This should be carried out at least once a year, as it will help prevent unexpected problems before they arise. It will also ensure that your unit is working properly and more efficiently delivering the maximum cooling effect with the least energy use.
AC units are normally very robust, but there are several reasons why they break down, requiring a heating and AC repair. But there are some warning signs that you should look out for to avoid this.
The Refrigerant is Leaking
Every HVAC unit needs an optimum level of refrigerant within it. Any leak will reduce this amount and start to cause problems. You might notice less cold air coming from your unit and frost and ice forming on the evaporator coil which can damage it.
Your unit will now have to work harder to maintain the temperature in your home, causing greater wear and tear, so reducing the working life of your unit.
A Frozen Evaporator Coil
Strangely enough, if the evaporator coil does not get enough airflow over it, it can freeze. When it does you need to turn the unit off to allow the coil to thaw. As the evaporator coil starts to freeze, other components in the HVAC must work harder and possibly overheat and breakdown, leading to expensive heating and AC repair bills.
Other factors that reduce the airflow are dirty air filters and blocked air return grills. These need regular replacing and cleaning. The evaporator coil will need cleaning too.
Dirt will build up over time and act as an insulating material, reducing the heat transfer between the warm air and coil. Regular service from Minuteman will help prevent these problems by cleaning the evaporator coil and HVAC unit.
The Condenser Is Dirty and Blocked
The condenser unit also needs plenty of air to flow over it. Because it is outside it gets coated with a layer of dirt. This reduces the transfer of heat to the outside air and will result in the condenser working harder causing it to overheat and burn out.
Regular cleaning is a good idea, so is removing any plants, grass, and weeds from around the condenser and fins. This is a job you can do yourself to avoid the need for costly heating and AC repair.
The Ducts are Leaking
If there is damage to the ductworks or the joints are loose, cold air will escape. A regular inspection of the ducts can save you a lot of money as up to 30 percent of an HVAC’s energy is wasted this way which means you’re paying 30 percent more for heating and air conditioning.
There are two fans in your HVAC unit, one blows warm indoor air over the evaporator coil, and the other blows outdoor air over the condenser. A damaged fan will restrict airflow over either unit. If you hear strange noises from the fans then call us straight away.
How Old Is Your HVAC unit?
Like all things, nothing lasts forever. Most HVAC systems will have to be replaced after 10 to 15 years. A regular service will extend the useful lifespan of the HVAC, but eventually, it will need replacing. An air conditioning repair on an older unit will cost more and more as the parts become harder to find. A newer model is more energy-efficient than an older one. They utilize newer and more environmentally friendly types of refrigerants that deliver greater effectiveness and comfort.
