Professional Heating & Furnace Repair Services Houston

Here in Houston, it’s easy to forget that we need to use our furnaces and heating systems from time to time. With an increasing amount of ninety-plus degree days every year, most of us in Texas use our heating systems less and less. Despite that lack of use, it is crucial to maintain and repair your heating system when required to ensure it’s working at peak efficiency. That rare time when you do need it, and you go to turn it on, you’ll regret that you can’t use it. 

Signs that you need heating repair

Many parts go into making up an efficiently functioning home or commercial heating system. Luckily for us, our HVAC systems can talk to us and let us know when it may be time for a professional heating repair service call. These are just a few signs you can look for that may indicate a problem somewhere in your heating system.

1. Cool or just not quite hot enough airflow

Colder than usual air coming from your heating vents can indicate multiple issues with your home or business heating system. There may be clogged air filters that need replacement, your pilot light could be out, or there could be a leak in your ductwork that is drawing cold air into your home from the attic or crawlspace.

First, check that your thermostat is set correctly and that it is set for “HEAT” or “AUTO” and not set to “COOL.” Also, check the set temperature to make it is below the room reading to engage the furnace. Suppose everything else seems reasonable, and you’re not getting adequate heat. In that case, it’s time to call in the services of a professional heating repair company.

2. Abnormal Furnace Smells

Furnaces tend to smell like the fuel they use, especially the first time they’re turned on during the year. The majority of furnace odors will decrease the more often the unit runs. But if you notice that the smell of fuel appears suddenly out of nowhere in your home and doesn’t decrease over time, it may be a sign of a more significant problem.

This smell can result from a wide range of problems, including a gas leak to excessive dust inside the unit itself. This is when you need to call Nick’s A/C. We’d be more than happy to come out and take a look at your heating system to determine the cause of the furnace smells.

3. Your furnace is rapid-cycling 

During regular operation, your heating system will cycle on and off, either every few minutes or every couple of hours. The frequency and duration of these cycles depend on your thermostat settings, the temperature of the air being brought into your home, and personal preference.

A furnace that cycles on and off very quickly and repeatedly is usually a sign of a faulty thermostat. Rapid cycling is a heating repair in Houston issue that needs to be remedied as soon as possible. The unit’s constant turning on-and-off causes undue wear and tear to blowers, burners, and other heating system components.

4. No heat at all

Furnaces that refuse to put out any heat are more likely than not to have some degree of a safety issue. There’s a whole list of reasons why your heating system isn’t warming your home or business. Gas leaks, worn out ignitions, and blown out pilot lights can create a significant hazard that is best dealt with by a licensed heating repair technician.

5. Poor air quality

An inadequately maintained furnace will simply shift the heat and dirt, bacteria, dust, and foreign particles around your home. You may notice more floating debris in your home, and you cough more, experiencing more colds and other respiratory ailments such as allergies or asthma. You might also find yourself suffering from headaches and watery eyes more often if you have a furnace that needs to be repaired.

The fix might be as simple as changing the filter. Or it might be more serious such as the ductwork requiring professional cleaning. Either way, it’s worth your health to investigate it! 

6. Tripped carbon-monoxide detector

Every furnace is equipped with a carbon monoxide detector. It is designed to alert you, the homeowner, to the toxic gases’ presence should they escape from the furnace. If the sensor goes off, turn the furnace off immediately and open as many windows as possible to ventilate your home.  

Speak with your gas company and an HVAC contractor to determine the source of the gas. The detector is installed as a life-saving device. Carbon monoxide is a deadly gas that is not visible to the naked eye. Please heed its warning.  

7. Ongoing noises

Sure, no furnace is silent. But loud and persistent noises are one way of your furnace trying to tell you that something is not working. Pay attention to the sounds you’re hearing. If possible, describe what you’re hearing to your HVAC professional when they do arrive. The more information you can give them the better! For example, squealing and whistling noises may be a sign that it’s a belt or fan issue. While banging or groaning noises might indicate it’s a broken or loose internal part.

8. Discolored pilot light

Have you ever noticed the color of your pilot light? Probably not. That’s okay; you’re not alone. But from now on, start paying attention.  A healthy pilot light usually appears blue. A pilot light of a different color, in particular yellow, can indicate a ventilation problem.  

The color change occurs when gases such as carbon monoxide don’t decrease as they should. This issue can cause health problems for you and your family or anyone else in your family. Address it immediately!

I called Nick’s Plumbing to complete a natural gas line replace and repair job after being frustrated with the incompetence of the supposed “expert” plumbers in West University Place. Nick’s employees were knowledgeable, friendly, and professional. They finished a job in a day that the prior company could not complete in a week – and at a much lower cost. Many thanks!

Called on Saturday around 11 am and they were onsite within an hour to help get our domestic pumps up and running for 200+ apartment homes. Fantastic service, communication, and personnel. Pricing was very reasonable too.
