Who Tests for Carbon Monoxide in the Home?

Mar 11

Quick Answer:
If you are wondering who tests for carbon monoxide in the home, the most common professionals are licensed HVAC technicians, plumbers, home inspectors, and sometimes your local gas utility company. In most cases, an HVAC company is the best choice because they can both test for carbon monoxide and repair the appliance causing the issue.

Who Tests for Carbon Monoxide in the Home?

Carbon monoxide is a colorless, odorless gas that can become dangerous very quickly. It forms when fuel-burning appliances such as furnaces, water heaters, fireplaces, or gas stoves do not burn fuel completely. Because it cannot be seen or smelled, many homeowners are unsure who to call if they suspect a problem.

So who tests for carbon monoxide in the home? The answer depends on the situation, but most of the time a licensed HVAC professional is the right place to start.

Heating systems are one of the most common sources of carbon monoxide. A trained HVAC technician has the tools to measure carbon monoxide levels inside your home and evaluate whether your furnace or other gas appliances are operating safely. They can inspect venting systems, check for cracked heat exchangers, test combustion performance, and make any necessary repairs.

For homeowners in Albuquerque, Horizon HVAC & Plumbing provides professional carbon monoxide testing along with heating inspections. If your concern is related to your furnace or another gas appliance, an HVAC technician can both diagnose and correct the problem.

Other Professionals Who May Test for Carbon Monoxide

While HVAC companies are often the most comprehensive solution, there are other professionals who may test for carbon monoxide depending on the circumstances.

Licensed plumbers can evaluate issues related to gas water heaters, boilers, or gas piping. If your concern is specifically tied to a water heater or gas line, a plumber may be able to identify the source of the issue.

Home inspectors also test for carbon monoxide, particularly during real estate transactions. If you are buying or selling a home, a home inspection may include checking for elevated CO levels. However, inspectors typically do not perform repairs. If they detect a problem, you will still need an HVAC or plumbing professional to fix it.

In emergency situations, your gas utility company or the fire department may respond if a carbon monoxide alarm is actively sounding. Their primary role is to confirm whether dangerous levels are present and ensure the home is safe. They do not perform appliance repairs, but they may shut off gas service if they believe there is a safety risk.

If your carbon monoxide alarm goes off and you experience symptoms such as dizziness, nausea, headache, or confusion, leave the home immediately and call 911. Safety should always come first.

When Should You Have Your Home Tested?

You do not have to wait for an alarm to go off before scheduling a carbon monoxide test. In fact, many homeowners choose to have testing performed as part of routine furnace maintenance.

It is wise to schedule professional testing if your furnace is more than ten years old, if you have recently installed a new gas appliance, or if you notice unusual odors, soot buildup around vents, or frequent pilot light problems. Recurring headaches or nausea when your heating system is running can also be a warning sign.

In Albuquerque, this is especially important during the fall and winter months when furnaces run frequently at night. Colder temperatures mean heavier heating use, and any combustion issue can become more noticeable during that time.

Can You Test for Carbon Monoxide Yourself?

Every home should have carbon monoxide detectors installed on each level and near sleeping areas. These devices are essential and can alert you when carbon monoxide reaches unsafe levels. Batteries should be replaced regularly, and the units themselves should be updated according to manufacturer recommendations.

You can also purchase handheld carbon monoxide monitors from hardware stores. These devices measure ambient carbon monoxide levels and can provide short term readings.

However, home detectors and handheld monitors only tell you that carbon monoxide is present. They do not determine why it is present. Professional testing goes further by evaluating how your furnace and other gas appliances are burning fuel and whether venting systems are working correctly.

What Causes Carbon Monoxide in Homes?

Most residential carbon monoxide issues originate from fuel-burning appliances. A cracked heat exchanger inside a furnace can allow combustion gases to mix with indoor air. Blocked or disconnected vent pipes can prevent exhaust gases from leaving the home. Water heaters, gas fireplaces, and improperly vented appliances can also contribute.

Another common issue is backdrafting, which occurs when exhaust gases are pulled back into the home instead of venting outside. Tightly sealed homes can sometimes contribute to ventilation challenges, particularly during cold weather when windows and doors remain closed.

In Albuquerque, many homes rely on natural gas for heating and hot water. That makes proper combustion and venting essential for indoor safety.

What Happens During Professional Carbon Monoxide Testing?

When an HVAC technician performs carbon monoxide testing, the process is thorough. They typically measure ambient air levels throughout the home and test combustion gases directly at the furnace and water heater. They inspect venting systems, look for signs of corrosion or blockages, and evaluate how efficiently appliances are burning fuel.

If carbon monoxide is detected, the technician works to identify the source. In many cases, correcting a venting issue or repairing a malfunctioning component resolves the problem. Because the technician can both test and repair, homeowners avoid the frustration of calling multiple companies.

Why Professional Testing Matters

Carbon monoxide is often called the silent killer because it provides no warning signs until symptoms begin. While detectors are critical, they only alert you after levels have risen.

Professional testing provides reassurance before a dangerous situation develops. Many homeowners schedule carbon monoxide testing at the same time as seasonal furnace maintenance. This proactive approach ensures the system is operating safely before heavy winter use.

For homeowners in Albuquerque who want added peace of mind, Horizon HVAC & Plumbing offers carbon monoxide testing as part of their heating and safety services. While several types of professionals can test for CO, working with a licensed HVAC company is often the most complete solution since they can identify and fix the root cause.
