What to Expect from Our HVAC Service
Your air conditioning system is the source of most airflow inside your home. Regular maintenance is key to prolonging life, improving indoor air quality, and saving on your power bill. As your unit declines in performance, your power bill will steadily increase. When you call Lang’s HVAC for HVAC maintenance, our licensed technicians inspect your system and ensure that everything is in working order.
Change Your Air Filter
Your air filter collects dirt, dust, and debris when the intake of your AC unit pulls in air. As the filter clogs with dust, your air conditioner has to work harder to pull in less air, which disrupts the efficiency of your AC unit and can lead to long-term problems over time. A dirty air filter is one of the most common HVAC problems faced in the industry, and it’s also one of the most straightforward fixes. We recommend replacing your filters every six months. We offer this simple service as part of our AC maintenance.
Furnace Repair
Furnace repair is quite different from working on an AC unit, but a few easy checks from our experts can prevent a costly repair. Our furnace repair service includes inspecting and replacing clogged or dirty air filters. We also check to ensure that the breakers leading to the furnace are not tripped and don’t have any broken parts or frayed wires. If your furnace isn’t heating up, see if the gas line is turned on. If so, you may have a clogged line or malfunction somewhere. No matter the issue, our team of HVAC experts arrives promptly, diagnoses the problem, and provides a free estimate for repairs.
Clean AC Unit Condenser Coils
The evaporator and condenser coils on your AC unit can get clogged with debris simply from being outside. Grass, leaves, trimming, mulch, and dirt can get embedded within the thin coils of your AC unit, causing it to pull in less cool air from outside. Make sure to trim any foliage back from the unit at least two feet to keep from restricting airflow. The coil fins may also become bent from debris collection or careless cleaning. Our licensed technicians use special combs to fix the coils and straighten them back out to keep your AC unit working for years to come.
