Even in today's technologically advanced age, HVAC technicians need to physically inspect air conditioning systems to keep them in good working order. Increasing reliance on technology-based air conditioning diagnostics hasn't meant that the role of an engineer who is on-site and inspecting equipment and ducting in person has been completely done away with. And yet, there are numerous tools available today for air conditioning diagnostics that provide precise measurements and rapid assessments.
Your home's AC unit may run great for years with proper maintenance, and then one day, it breaks down completely. If the problem is too severe for you to fix, hire an AC repair contractor. They'll save you a great deal of trouble in several ways.
Complete Industry-Standard Repairs
Even if you know a lot about HVAC units for residential properties, it can still be challenging to complete industry-standard repairs. After all, you haven't gone through training or shadowed an experienced repair contractor for years.
Modern furnaces typically forego the old-style pilot lights and instead use a more modern hot surface igniter system. These components have a shockingly descriptive name. Unlike more complex ignition systems, a hot surface igniter passes enough electricity through a plate (the surface) to heat it until glowing red. This hot surface ignites the gas when your furnace needs to light.
Unfortunately, this simple device can also be a source of some trouble.
You'll want your air conditioning system to be in good shape before the hot days of summer set in. One way to do that is to have an annual tune-up that involves servicing and cleaning the equipment. However, if your AC is old, that might not be enough to keep the parts going all summer. If your AC is old, it could be time to replace it. Here are five signs it could be time to get a new air conditioner.
Furnace maintenance helps your furnace operate safely and efficiently. Maintenance can keep your furnace from breaking down over a preventable problem. Plus, regular professional maintenance may be needed to maintain your warranty. Here are parts of your furnace that need to be checked by a professional when doing annual maintenance.
The Blower Motor And Fan
The blower needs to be clean so it can spin without obstructions. The furnace maintenance technician will probably need to scrub the squirrel cage to get dust out of the gaps between the blades.
