A/C had been out for a couple days. Heat index 105° , 90 ° in house. I called 15 + HVAC companies and the earliest appointment time anybody could come was a week away. I called Barneys . He shot me straight and told me " I'll get you up and going today but it's going to be in the evening." He showed up about 7 pm which is perfectly fine as it was hot. He fixed the problem in 15 mins ( needed refrigerant ) He charged a very fair price. He stands by his word. LIFESAVER!! VERY COOL NOW!!!

HIGHLY RECOMMEND!!! My A/C went out late Friday night and not many companies were wanting to help and look at my unit until after the weekend and holiday was over, but Barney’s heating and air responded ASAP, and was here first thing in the morning on Saturday! The technician gave me an exact time and was here on time, other companies gave me a big time frame/window 8am-6pm and that just didn’t work for us. This company is affordable and willing to work with you. Definitely will call them again!! Thank you!

First time (in this house) getting our heat pump inspected. Technician was detailed in explaining what was both good & bad about our 12 year-old system. He explained that our system was still functional but also showed us a part that might fail in the future. He tested the part in our presence & gave us a fair price for replacement (which we did). We were comfortable enough with the service that we are likely to purchase a service/maintenance agreement this Fall.

His work is top notch quality, this is the 3rd time we have used him for our rentals and will continue to do so in the future. Highly recommend for your AC/HVAC needs.

I was having problems with my HVAC system and I called these guys to come check it out. Bobby and Jacob are very down to Earth guys. Bobby was very upfront about what issues I had with my system and gave me recommendations without feeling like they were trying to push anything on me. I was impressed with the knowledge he had and how fair their pricing was. I'm a single woman that lives alone with my children and I did not once feel uncomfortable with them or feel like they were trying to get over on me. They ended up installing a new unit in my home and did an amazing job. I have not had one issue with it since. I would def. recommend this company to anyone I know! Thank you guys!!

Most Common Furnace Repair Questions

When your furnace fails in the middle of a cold spell, it can be stressful. Having some knowledge about common furnace issues can help you understand the situation. Here are answers to some of the most frequent questions we get about furnace repair.

The cost of a furnace repair is highly dependent on the specific part that has failed and the labor required to replace it. Minor repairs are the most affordable. These include things like cleaning a dirty flame sensor, replacing a single furnace filter, or fixing a simple wiring issue. These jobs do not involve expensive parts and can usually be completed relatively quickly. For these types of common, simple fixes, you can expect a lower repair cost. We always provide a firm, upfront price for any repair before we start the work.

Mid range repairs involve replacing more significant components. This category includes repairs like replacing a hot surface igniter, a gas valve, or a draft inducer motor. The parts for these repairs are more expensive than simple components, and the labor can be more involved. For example, replacing an inducer motor requires disconnecting the venting and electrical wiring, removing the old motor, and installing the new one. These are very common repairs for furnaces that are several years old. We will always show you the failed part and explain why it needs to be replaced.

The most expensive furnace repairs are those that involve replacing the main control board or the blower motor. The control board is the central circuit board that controls all the furnace’s operations, and it can be a costly part. The blower motor is a large and essential component, and its replacement is a labor intensive job. In these situations, especially if your furnace is older, we will have an open conversation with you. We will discuss the cost of the repair versus the potential cost of a new furnace, helping you make the most sensible financial decision for your situation.

Deciding between repairing and replacing your furnace is a significant decision that depends on several key factors. The first and most important factor is the age of your furnace. A typical furnace has a lifespan of about 15 to 20 years. If your furnace is in this age range or older, investing in a major repair may not be the wisest choice. It is likely that other components will start to fail soon, leading to more repair bills. For an older unit, especially one needing a costly repair, replacement is often the more logical long term solution.

The cost and frequency of the needed repairs are also critical considerations. If your furnace has been reliable and this is the first time it has needed a minor repair, fixing it is usually the right call. However, if the estimated repair cost is very high, you should weigh it against the cost of a new unit. A common industry guideline is to consider replacement if the repair cost is 50 percent or more of the cost of a new furnace. If your furnace has needed multiple repairs in the last couple of years, it is a strong sign that it is on its last legs.

You should also think about the energy efficiency of your current furnace. Furnace technology has improved dramatically over the last two decades. If you have an older, standard efficiency furnace, replacing it with a new high efficiency model can lead to substantial savings on your winter heating bills. The money you save on fuel each month can help to offset the cost of the new furnace over time. A new furnace also comes with a new warranty, providing peace of mind. Our technicians can give you a quote for the repair and a quote for a replacement, allowing you to compare the numbers and make an informed choice.

Loud and unusual noises from your furnace are almost always a sign that a component is loose, worn out, or failing. The type of noise can often give us a clue as to the source of the problem. A high pitched squealing or whining sound that is persistent usually points to an issue with the blower motor. The noise could be coming from a worn out belt on an older furnace or, more commonly, from failing motor bearings. This requires immediate attention, as a failing motor can burn out completely if left unaddressed.

A loud banging, popping, or booming sound that happens when the furnace first kicks on is often caused by dirty burners. When the burners are clogged, gas can build up in the combustion chamber for a few seconds before it finally ignites. This small, delayed explosion is what causes the loud bang. This is not only alarming but can also put stress on the heat exchanger. The issue could also be related to expanding and contracting ductwork, but it is important to have the burners checked and cleaned by a professional.

Scraping or grinding noises are a very serious sign. This often indicates that a component has come loose and is hitting another part. The most common cause is a loose or broken blower wheel. The wheel could be scraping against the blower housing as it spins. This is a critical problem that can cause extensive damage. If you hear a scraping or grinding noise, you should shut your furnace off at the circuit breaker immediately and call for an emergency repair. Continuing to run the furnace could destroy the blower assembly.

If you smell natural gas in your home, you must act immediately, as this is a potentially dangerous situation. The smell is often compared to rotten eggs or sulfur; gas companies add this odorant, called mercaptan, to the naturally odorless gas to make leaks detectable. The first and most important thing to do is to avoid creating any sparks or flames. Do not turn any lights on or off, do not unplug any appliances, and do not use your phone inside the house. Any of these actions could create a spark that could ignite the gas.

Your next step is to get everyone, including pets, out of the house immediately. Leave the door open as you exit to help ventilate the house. Once you are a safe distance away from your home, use your cell phone or a neighbor’s phone to call 911 and your local gas utility company. Their emergency line will be available 24/7. Report that you smell gas and give them your address. Do not go back inside your home for any reason. Wait for the utility company technicians to arrive. They are trained to handle gas leaks and will make the situation safe.

The utility company will find the source of the leak and shut off the gas supply. If the leak is determined to be coming from one of your gas appliances, such as your furnace or water heater, they will “red tag” the appliance. This means it is unsafe to use until it has been repaired by a qualified contractor. Once the utility company has declared your home safe to re-enter, you can call Barney’s Heating and Air. We can then come and perform the necessary repairs on your furnace’s gas line or components to resolve the issue safely.

Short cycling is the term for when a furnace turns on, runs for a very short period (often just a minute or two), and then shuts off again. This process then repeats over and over. This is not normal furnace operation and it is a sign of an underlying problem. The most common cause of short cycling by far is a dirty and clogged air filter. The filter is designed to trap dust and debris, but if it is not changed regularly, it can become so blocked that it severely restricts airflow. This lack of airflow causes heat to build up inside the furnace very quickly.

Your furnace has a safety device called a high limit switch. This switch monitors the temperature inside the furnace cabinet. If the temperature gets too high, the switch will shut down the burners to prevent the furnace from overheating and becoming a fire hazard. With a clogged filter, the furnace overheats rapidly, the limit switch trips, and the furnace shuts down. After it cools for a few minutes, it will try to start again, and the cycle will repeat. Before calling for a repair, you should always check your air filter and replace it if it is dirty.

If a clean filter does not solve the short cycling issue, there are other possible causes. The problem could be a faulty high limit switch that is tripping at too low a temperature. It could also be a problem with the thermostat’s location or calibration, causing it to send incorrect signals. In some homes, the furnace itself is drastically oversized for the house. An oversized furnace will heat the space so quickly that it satisfies the thermostat almost immediately, leading to constant short cycling. A technician can diagnose the specific cause and recommend the appropriate solution.

Yes, certain furnace problems are considered emergencies and require immediate attention. The most critical emergency is if you smell natural gas. As discussed earlier, this is a serious safety hazard that requires you to evacuate your home and call 911 and the gas company immediately. Another clear emergency is if your carbon monoxide detector goes off. This indicates the presence of this deadly gas in your home. You should evacuate immediately and call 911. We can then be called to find and fix the source of the CO leak in your furnace.

A furnace that is making loud, violent noises like grinding or banging should also be treated as an urgent issue. These sounds often indicate a serious mechanical failure, such as a broken blower wheel. Continuing to run the furnace in this condition could cause catastrophic damage to the system. You should shut the furnace off at the breaker and call for a repair right away. Similarly, if you see smoke or smell a strong burning odor coming from your furnace, shut it down and call for service immediately, as this could be a sign of an electrical fire or a severely overheating motor.

Of course, the most common type of furnace emergency is simply a complete loss of heat during freezing cold weather. While not an immediate safety hazard in the same way as a gas leak, it can quickly become one. A home without heat can experience frozen and burst pipes, which can cause thousands of dollars in water damage. It can also become dangerously cold for the occupants, especially for young children or the elderly. At Barney’s Heating and Air, we offer emergency repair services to address these urgent situations and restore your heat as quickly as possible.
