Everything You Need to Know About HVAC Repair

HVAC systems are expensive investments for homeowners, so they must be well-maintained. Regular maintenance can prevent many problems that cause costly repairs and replacements.

Maintenance technicians can spot minor issues before they become more significant problems requiring expensive system replacements. This can save homeowners money in the long run, making a service contract worth it for most.


No matter how careful you are with your HVAC system, it’s inevitable that you will encounter problems at some point. Luckily, not all issues are as big a deal as you think. You can try some simple troubleshooting techniques before calling in the professionals at B&L Ott.

First, start by turning off the power to your HVAC system at the breaker or fuse panel. Inspect the wiring, looking for any signs of wear or damage. If you notice any, turn off the power again and contact a professional to make repairs.

Next, check the airflow in your home. Ensure your vents are open and unobstructed and the air filters are clean. Also, inspect your ductwork for leaks and other issues impacting airflow. Finally, check the humidity levels in your home to ensure they are within the design parameters of your system. If they are not, install a dehumidifier.


The first step in residential hvac repair involves inspecting the equipment. An HVAC technician usually checks the air filter and the evaporator coil for dirt. They will also look at the fan motors and belts. These components can be a source of noise and can shorten an HVAC system’s lifespan.

The next step is cleaning the HVAC unit’s drain line, which can become clogged with algae, mold, and sediment. This task can be accomplished by using a wet/dry vacuum or detaching the line and pouring bleach.

Many of the problems that can lead to a costly HVAC repair bill can be prevented with regular maintenance. This includes scheduling two precision system tuneups annually and changing the air filter monthly.

In addition to avoiding costly repairs, routine HVAC maintenance can extend the lifespan of your HVAC system and help you save money on energy bills. Many HVAC systems last up to 15 years with proper maintenance.


If regular maintenance doesn’t fix a problem, or the system is approaching its recommended lifespan, it might be time for a replacement. The warning signs include high utility bills, strange sounds or odors, and electrical issues.

HVAC specialists use their tools and knowledge to remove, inspect, clean, and replace the parts that keep a unit running. Some components are more easily replaced, and some require special tools or know-how. Run capacitors and start capacitors — which keep electricity flowing and help to create the current — are easy to replace, as are blower motors and air filters.

Air ducts and vents can become dusty or dirty over time, leading to weak airflow. Keeping furniture and clutter away from vents, vacuuming ducts occasionally, and replacing filters can help keep them working well. It’s also a good idea to sign up for an HVAC service plan, which includes two precision system tuneups per year and a 15% discount on all repairs.


Regular maintenance is essential to ensure your HVAC system lasts as long as possible. These maintenance tasks include cleaning ducts and vents, replacing air filters, and more. They’re also the best way to keep your energy bills low.

But what happens when your system stops functioning correctly? This can happen for several reasons. Perhaps it’s a simple fix like a new air filter or something more serious, such as an electrical problem.

If you notice that your system isn’t producing cool air or turning on and off constantly, it may be time to call a professional. A technician can identify and repair problems to ensure a safe, comfortable home.

They can also help you find ways to reduce your energy bill with efficient systems. They may even offer a free inspection! Keeping up with your HVAC system can be challenging, but it’s an essential investment in your home.
