When you notice that your HVAC system isn’t running properly, there may be many problems to look for. In many cases, the HVAC unit may be simply experiencing a power outage. To troubleshoot this, turn off your circuit breakers, and then turn them back on. Additionally, if your HVAC unit has a battery-operated thermostat, check to see if the batteries are dead. If these steps don’t solve your problem, you should have it serviced by a trained HVAC technician.


If you have a broken heating system, you may be wondering what the problem is. While furnaces and other heating systems make some noise during normal operation, loud noises usually mean that you need to have a heating repair performed. Similarly, loud screeching noises could indicate a worn-out or faulty motor bearing. In such cases, you need to have a professional service technician come and check the problem. In this article, we’ll discuss some common heating problems and their solutions.

Broken or malfunctioning heating systems can be an emergency. Without proper repair, these units will struggle to keep a home warm, which increases wear and tear and decrease efficiency. Inefficient heating systems will cause your utility bills to soar. In some cases, you may have to spend hundreds of dollars more than necessary this winter if you don’t have this issue addressed. Heating repair will restore efficiency and keep bills low. Having a broken heater can be uncomfortable, and can even compromise the safety of your home and family.


Heating and cooling technicians are responsible for more than just HVAC systems. Today, people spend more time inside their homes than ever before, and indoor air quality, home energy savings, and total comfort are all incredibly important. HVAC systems are also available in a wide variety of configurations, so finding the right one is essential for total comfort in your home. Luckily, there are many options when it comes to HVAC systems, so your technician can help you choose the right one for your needs.

Getting an HVAC technician to come to your home for maintenance is important for several reasons. First, regular maintenance will keep your cooling system in top shape and prevent future repairs. Additionally, it will help your energy bills stay lower, as well. Aside from the cost of repair, regular maintenance will improve your system’s efficiency and keep your home cooler. But if you’re too busy or have too much work to do, hiring an HVAC company is a great way to save money and get the job done quickly.

Indoor coil

If your indoor coils are bent or rusted, you can try to comb them back into shape yourself. However, it is difficult to do this without hiring the services of a professional. While this may not be a viable option in Arizona, it is still a better option than paying for an expensive new air handler. If you have a 10-year equipment warranty, it is a better choice because it covers all parts of the unit.

If you can, you should clean the indoor coils regularly. You should change the air filters at least once a year, preferably when you use the air conditioner. If you do not do this, you may push dirt to the center of the coil, causing even bigger problems. The BTU output of any coil is directly related to the amount of air passing through it. Dirt in the center of the coil reduces airflow and can even corrode the fins.


In order to troubleshoot a malfunctioning thermostat, it’s best to contact a professional HVAC service company. A poorly located thermostat may not regulate the temperature properly, because it’s not level or protected from other heat sources. Also, a dirty thermostat may cause short cycling or continuous operation, reducing the efficiency of the HVAC system. Here are a few ways to troubleshoot a malfunctioning thermostat and prevent it from becoming a costly repair project.

It’s also important to replace an old thermostat if you have an older model. This may be due to frayed wiring or other damages that affect the connection to the HVAC system. It may also be a problem with the temperature sensor, which can be damaged by misuse or age. If the temperature readings fluctuate rapidly, it might be time to replace the thermostat.
