Tasks You Can Do Yourself For Preventive HVAC Maintenance. 

Manufacturer AC maintenance periods are fixed after considerable testing and analysis. Here are some HVAC maintenance tips that you can do.


Remove Cobwebs - Clean The Critical External Unit (Condenser and Compressor)

  1. Turn off Power at the main electrical panel.
  2. Clear weeds, leaves, debris around the outdoor unit. Air flow is critical for efficient operation.
  3. Clean and straighten the air conditioner fins. Dirt can accumulate between fins. Use a brush or knife if tough to brush off.
  4. Clean condenser fan. A lot of dust and debris can accumulate over time and it needs to be cleaned at regular intervals. Use a damp cloth to remove dirt, leaves.
  5. Clean fins inside out. Spray fins with a garden hose to remove dirt.
  6. Learn how to clean AC video


Inspect The Coils For Grime And Conquer It - Clean Inside Unit (Evaporator and Blower)

  1. Clean evaporator coil.  The door is usually inside the furnace and a lot of dirt builds up there. Use a soft brush to move dust out of the way then spray it with a no-rinse coil cleaner improve its efficiency. You can also use mild detergents and water to get rid of the dirt between the coils.
  2. Evaporator drain can get clogged due to the buildup of algae and mold, and it needs to be unplugged. Clogged PVC drain can cause flooding, odors, even stop HVAC from cooling. You can use a wet/dry vacuum cleaner to get rid of debris in the evaporator drain.
  3. Change blower air filter. Dirty air filter can stop the unit, increase utility costs and damage the unit. Change at least twice a year. Check monthly to see how dirty the filter is.
  4. Call PDM for professional air conditioning maintenance.


A PDM Professional Revitalizes Your Cooling System With Six Critical Adjustments. 

#1 cause of air conditioning failure and wasted energy is dirt and neglect. We will clean the winter cobwebs, rust, dirt. Test for electrical faults, safety controls, and system operating pressures. Calibrate and reset the finer points to squeeze every ounce of efficiency and comfort from your residential and commercial HVAC maintenance.

  1. Electrical System Problems - test for loose connections and weak components that lead to breakdown and unsafe conditions.
  2. Air Movement System - poor airflow creates hotter or colder rooms and wastes energy. Air quality weakens. Clogged, dirty air filtration can restrict airflow by 65%, even overheat cooling unit.
  3. Dirty Exterior Condenser Coil - when clean improves efficiency and cooling performance.
  4. Test Refrigerant System - AC runs longer and shortens life with low refrigerant.
  5. Duct Connections - obstruction from debris or leaking duct wastes energy and affects air quality. Inspect for dirty air ducts and visible air leaks.
  6. Condensate Drainage System Inspection - avoid odors, standing water, water damage, ac unit not cooling, even shuts down.

  • Your AC unit’s warranty can be voided. 

When you consider everything that can go wrong when you do not have your AC unit regularly serviced, it’s clear that a maintenance plan from a trusted professional is well worth the investment.

Why is my air conditioning freezing up?

When your AC unit is freezing up, something has altered your system that cools your evaporator coil more than it should, causing the unit to freeze up. Your air conditioning unit may be freezing up because: 

  • Your AC unit has blocked or low air flow. 
  • Your AC unit is being used too frequently.
  • Your AC unit has broken parts. 
  • Your AC unit is poorly maintained.
  • Your AC unit has low refrigerant levels. 

This problem won’t go away and can damage your AC unit’s compressor. You should check your air filter to see if it is clogged or dirty. You may find the problem is simply due to a dirty filter, which can block over 60 percent of the air flow and stress your system. Replace the air filter or remove it and see if cooling returns. You should let the frozen refrigerant lines thaw first before using the AC. If the problem persists, you may need to have your AC unit repaired by an HVAC technician.

Why is my air conditioner making a noise?

Your air conditioner may be making a noise due to damaged ducts, a clogged air filter, fan problems, coil damage, loose parts, faulty motor bearings and belts and even electrical issues. Some noises your air conditioner may make include: 

  • A squeaking, squealing or screeching noise -  can be due to an issue with the compressor, fan motor, bearings or damaged blower belts. 
  • A loud buzzing noise - is usually due to an electrical problem. 
  • A clicking sound - can mean your system relays or contractors are failing. 
  • A humming or rattling fan motor noise - can indicate that your AC unit needs to be cleaned, has a worn-out part or has bent or shifted blades. 
  • A banging, whining or whistling noise - can signal poor airflow problems related to leaky air ducts or a clogged air filter. 
  • A hissing noise - is usually due to a refrigerant leak. 
  • Shaking and rattling noise - can be caused by loose air conditioner parts related to air movement. 
  • Constant running noise -  can be due to bent outdoor coil fins. 

If your air conditioner is making a noise, but you cannot diagnose or repair the problem yourself, you should have an HVAC technician diagnose and repair your AC unit for you. To get your AC unit repaired, give us a call today

Brennon was very professional. He originally came to check my AC. When he found problems, he immediately told me, explained the issue, and let me know the cost. Once I gave the okay, he was able to repair the issues quickly. -- Jan B.
