Frequently asked questions about hvac repair technicians

There are many reasons your HVAC system may not be working, and be in need of repair. One very common root cause of HVAC failure is simply a lack of regular maintenance. HVAC pros recommend that your system be checked annually to keep it in top repair. If your AC unit of furnace is not performing up to standards, it is often best to an HVAC contractor assess your system to see what kind of repairs it may need. A pro will know that if your furnace is tripping the circuit breaker, it may be because of a dirty filter. The dirt could be blocking the air flow. But the issue could also be a duct leak or dirty coils.

A malfunctioning HVAC system could actually be hazardous. If your furnace is making strange noises, the motor may need to be replaced. Your HVAC system may have airflow issues or dirty burners that might be flammable. It’s always best to stick to a regular HVAC system maintenance schedule, and to consult an HVAC repair contractor at the first sign that your HVAC is not working.

Air conditioners are great for keeping your home comfortable in the warmer months. Having an AC unit installed brings a host of other benefits as well. However, air conditioners are subject to a host of common problems. One of the most common problems starts with a lack of regular HVAC maintenance. One common AC system issue is a gradual or sudden decrease in efficiency. The air conditioner may not be cooling your home well, and your home might feel unusually muggy. If HVAC maintenance has been neglected, the coils may have collected dirt and debris which clogs the coils. An air conditioner repair pro can remedy this situation, and check for any other problems with your air conditioner. Similarly, if your AC unit is leaking, a pro can troubleshoot the problem.

It makes sense to keep a regular HVAC system maintenance schedule. If you bring in a local AC professional, they can get to know your system and call out problems with your air conditioner before they become bigger issues down the road.

Your home’s heating and cooling system may be easy to take for granted as long as it is running smoothly. Your HVAC system keeps your home comfortable, it can save on energy bills, and it keeps the air in your home cleaner and healthier. Here’s the catch, your HVAC system requires regular maintenance to keep it in top repair. Investing in an annual inspection of your home’s heating, ventilation and air conditioning systems is relatively inexpensive compared to the benefits you’ll enjoy.

Regular maintenance helps prevent expensive breakdowns by troubleshooting the HVAC problem early and effectively. If you have your HVAC system inspected and maintained on a regular basis, your system will run more efficiently which can save you money on energy bills. Annual maintenance can extend the life of your HVAC system saving you money on costly replacements. Finally, most HVAC companies require proof of regular maintenance when a repair is submitted under warranty. It pays to keep your heating, air conditioning, and ventilation systems covered on a warranty. An HVAC pro can help you with routine HVAC maintenance as well as big and small repairs.

There are a host of common HVAC problems that can lead to annoying, expensive, or even dangerous situations in your home. Carbon monoxide leaks are one potentially dangerous HVAC problem. These can be caused by a cracked or failed heat exchanger. An HVAC repair pro can test for the presence of carbon monoxide in your home and install a carbon monoxide detector in your home. Another potentially dangerous problem that can arise with your HVAC system are pilot light or ignition problems. A dirty pilot, or burners can cause short cycling, a pilot outage, or furnace lockout. In any case it’s best to call an HVAC repair professional. HVAC problems that involve natural gas or high voltage which must be handled by a trained technician.

If your furnace or air conditioner is suddenly making odd noises, emitting strange odors, or seems to be operating less efficiently than when it was installed, it’s time to call an HVAC repair technician. A trained pro will have the skills, know-how, and tools to safely repair any problem your HVAC system develops over time. Keep your home safe, comfortable and healthy by developing a regular maintenance and repair relationship with an HVAC pro near you.

There are a few simple troubleshooting steps homeowners can take if their HVAC system is not working. After taking these steps, it makes sense to hire an HVAC repair technician. Many problems that come up with furnaces, air conditioning and ventilation systems can be annoying, expensive, and even dangerous. A trained tech will have the skills, tools and know how to tackle any more complex troubleshooting your HVAC system breakdown requires. Homeowners can make sure the furnace or air conditioner is properly plugged in. They can make sure the air space around a furnace, air conditioner or duct system is not obstructed by furniture or plants. Homeowners may even be able to check some filters, and change and clean them. Beyond that, bring in a pro.

An HVAC repair professional will know how to safely work with potentially dangerous natural gas and high voltage electrical systems. If your air conditioner, high-efficiency furnace or water heater is leaking, a trained HVAC repair tech can troubleshoot the problem and fix it efficiently. HVAC leaks can cause costly water damage if they are not taken care of quickly and efficiently. Trust your HVAC troubleshooting to an HVAC professional.

If your air conditioner is running but it is not cooling house, there could be a number of reasons. The simplest troubleshooting step for your AC problem is to check whether your thermostat is set to “on” or “auto.” If your AC thermostat is set to “on” the system will run the fan continuously whether or not the air is being cooled. Make sure the air conditioner is set to “auto.” You can also make sure the filters in the AC unit are clean.If the filter is dirty, simply replace it.

However, it makes sense to bring in an HVAC repair pro to address issues that are more complex. If your AC unit can’t cool your home on hot days, but cools the air just fine on cooler ones, your air conditioner may have low refrigerant. This means you may have a refrigerant leak. The signs of a leak are a bubbling or hissing noise, ice build up, If you notice these signs, turn the AC unit off and call a pro. This issue can damage the compressor which would mean having to replace the air conditioner’s outside unit. Call a pro to troubleshoot your AC issue to save money and headaches down the road.
