Homeowners must balance several considerations when deciding whether to repair or replace an air conditioner. They should consider the cost of a new unit, warranty terms, and the benefits of energy efficiency.
The fan inside your outdoor unit’s blower can clog, cutting off the cool airflow to your home. Pro Master Heating & Air Conditioning can clear up this clog and restore normal airflow by defrosting the evaporator coil.
The thermostat is the most important piece of equipment in your air conditioning system. You use it multiple times a day and it controls your entire HVAC system. When your thermostat starts acting up, it can lead to problems for your AC unit. Luckily, it’s usually easy to get your thermostat fixed before you have to call for an AC repair technician.
If your thermostat is constantly losing power, you should first check to see if the breaker for it has been tripped. You can do this by looking at your circuit breaker panel and checking to see if the switch is hovering between the “off” and the “on” position. If the switch is on, then it may just need to be reset.
Another common cause of a thermostat losing power is the accumulation of dirt and dust on its mechanical and electrical components. Make sure you shut off the breaker before opening your thermostat’s cover and cleaning it. You can use canned air or a brush to clear away any loose dust, soot, cigarette smoke, or other debris that has settled on the thermostat. Once you have the cover off, you should also examine the terminal connections. Loose wires can be a source of thermostat failure, so you should tighten any loose ones as soon as possible.
The location of your thermostat can also affect its ability to accurately regulate your home’s temperature. It should be located away from direct sunlight, other heat sources, and cold drafts and placed five feet above the floor to ensure an accurate temperature reading.
Older thermostats tend to break down more easily than newer ones. If yours is more than 10 years old, it’s a good idea to consider replacing it with a newer model that will save you money on your energy bills.
Thermostats can start to fail if they are subjected to extreme temperatures. If you live in a particularly hot or cold climate, then you should regularly inspect your thermostat to make sure that it is still functioning properly. A newer thermostat will likely have more advanced programmable features that can help you save even more on your utility bills.
The condenser is the heart of your air conditioning system. It is responsible for collecting heat from the air, removing it, and then recirculating it throughout your home. As with any piece of equipment, the condenser needs to be maintained regularly to ensure it works at maximum efficiency. This maintenance includes cleaning the unit, checking that all wires are fastened securely, and lubricating moving components like the fan. This maintenance can help prevent more expensive repair bills down the line.
It’s also important to remember that the condenser is usually located outside, which makes it more susceptible to damage from weather elements. This can include falling debris or rocks hitting the unit, and it may also be subjected to corrosion from pollutants in the environment.
Signs of a damaged condenser can vary greatly depending on the nature of the problem, but one common issue is that your AC is not cooling as well as it normally does. A decreased capacity is caused by a blockage in the condenser, meaning that heat and humidity cannot escape and will instead be recirculated through your home.
This is usually a clear indication that the condenser needs to be cleaned. A professional can help to clean the unit and remove any dirt or debris that may be blocking its vents.
Another common issue is a faulty relay switch or motor. These parts control the large fan in the condenser, and if they stop working, the whole unit will stop functioning correctly. These issues are generally easy for a technician to fix, but they should only be attempted by someone who is familiar with working on air conditioners.
Other signs of a faulty condenser are excessive leaks or a burning smell. Since the seals and condenser tubes are not replaceable, any significant leaks indicate that it is time to get a new one installed. A burning smell is more alarming and should only be left to a professional.
The blower is the fan that pushes conditioned air through your home’s ductwork to attain comfortable temperatures. The blower motor is a critical component of your HVAC system, so when it’s not working properly, you will notice weak airflow from the vents. A variety of issues can be to blame for poor airflow from the blower, including dirt accumulation, an aging motor or a faulty capacitor.
When your AC system is working correctly, the blower motor will operate at a pre-set speed to circulate the air through your ducts and your home. The speed is either preset by your heating and cooling repair company during installation or influenced by smart gadgets such as the programmable thermostat. Occasionally, the belt connecting the motor shaft to the squirrel cage/fan can stretch or slip, preventing the blower from turning at a proper speed. If this happens, a qualified heating and air conditioning technician can help with an easy fix.
Another sign that your blower motor isn’t working properly is if you notice an unusually high energy bill. Because the blower motor works harder to meet your home’s temperature needs, it uses more energy throughout your house.
Other signs of an inefficient blower motor include an unpleasant burning smell and an overheated unit. These symptoms are likely caused by dirt accumulating over time, which can cause the motor to overheat. In addition, moisture can corrode components and short circuit them.
You might also notice an increase in the number of strange sounds coming from your ductwork. Screeching and squealing noises are signs of a bearing problem, which can often be fixed by lubricating the motor. Loud banging sounds are more serious, indicating that there may be loose or broken parts.
The air filter is the most often neglected item on an HVAC system, but it has a huge impact on your home’s comfort and your energy bill. Dirty filters restrict air flow, causing your AC to work harder than normal. The extra strain causes your system to use more energy, which you’ll notice on your next utility bill. A dirty filter can also lead to other problems, such as an overheated unit.
When your air conditioner’s filter is dirty, it will allow dust, dander and other pollutants to circulate through the air ducts and into your home. This can cause respiratory issues and even mold in the ductwork. If you have children or pets with respiratory allergies, it’s especially important to change your air filter regularly.
Changing your air filter is an easy task that can be done by yourself. First, you will need to locate the filter, which is located either in the return air duct or the air handler cabinet. Once you have found it, you will need to shut off power to the unit at the circuit breaker or fuse box. Next, gently remove the filter and clean it (if possible) or replace it with a new one. When you reinstall the new filter, make sure that the airflow direction matches the marked arrow on the filter.
If the filter is so dirty that it completely restricts air flow, your AC will not be able to cool the home. This can be a major issue on a sweltering Nevada summer day! A dirty filter can also exacerbate minor mechanical issues with the unit and cause rapid wear of equipment parts. Eventually, the extra strain on your air conditioner will lead to serious problems that require professional AC repair.
