Winter Affects HVAC Operations

When you least expect it, HVAC issues can occur when you do not regularly maintain your equipment, or you opt to skip on an annual HVAC inspection by the professionals at Expert Air. HVAC repairs can be costly, and it only takes one or two repairs to see the benefit in regularly scheduled inspections by certified technicians. Consider the perks of maintenance programs, like ours, click here.

Some common HVAC issues include:

  1. Faulty Thermostat Readings
    1. Feel like the thermostat isn’t displaying the right temperature
    2. Thermostat placement may need to be changed
    3. Thermostat upgrade may be needed
    4. Thermostat repair may be an option
  2. Inconsistent Room Temperature Setting
    1. Causing discomfort and increased energy bills
    2. Culprit could be debris, rectified by a proper cleaning and filter replacement
    3. Potentially major HVAC issue
  3. Frozen Evaporator Coils
    1. Likely the airways are clogged or too low of temperature setting on unit
    2. We advise not setting the temperature below 60 degrees
    3. You need an inspection done immediately

 

HVAC Tips for Texas Winter

  1. Clean the Furnace Air Ducts
    1. Year-round contents in the air clog the air duct – dirt, pollen, smoke, pet dander
    2. Cleaning or replacing every 6-months is best in Texas
  2. Replace Parts on Unit that are Worn-Out
    1. Proper inspection is needed if unit is 5+ - years old
    2. Schedule inspection if you have the following issues
      1. AC not blowing cold air
      2. Heater not blowing hot hair
      3. Furnace is loud
      4. Power issues are observed
  3. HVAC System Upgrade
    1. Newer models are energy efficient
    2. SEER (Seasonal Energy Efficient Rating) models are best
  4. Clear Debris Around HVAC System
    1. Leaves and yard debris should be kept clear of HVAC system
    2. Leaving unclear will lead to bacteria and mold build up that gets into your system and in the air you breath
  5. Schedule Routine Maintenance with Expert Air
    1. From routine maintenance to unplanned inspections, repairs, and installations, the certified technicians at Expert Air, are ready to help

Heating Tune Up

In a world full of mechanically operated parts in various industries, something to consider when it comes to maintenance and tune ups – “The Law of Moving Parts” that states, that moving parts will wear out…and like Murphy’s law, will wear out at the worst possible moment, leaving you in the cold without heat. No one wants to be without heat in the dead of winter or even in the milder cooler temperatures. Heat is a basic need for survival and heating units are a great luxury we often oversee and down play on importance. It’s important to have your heating unit maintained on a regular basis.

The obvious benefits to heating tune-ups include safety, saving money on utilities, and sleeping comfortably.

Expert Air believes in going above and beyond with all services. We want you to trust us with your home equipment for a/c, heating, and HVAC services, so we check your equipment like it was in our own homes.

See a snippet of our tune up/check-up for the level of thoroughness and just how you can benefit from this regularly practiced maintenance proactiveness.

1. Inspect, test and calibrate controls and safety mechanisms

Safety controls are designed to shut down equipment when unsafe conditions are detected to prevent fires, gas leaks and other dangerous situations as well as to protect the equipment from catastrophic failure. Testing and calibrating these controls ensure safe operation of your equipment.

2. Lubricate motors and bearings

Lubrication prevents friction in motors which can increase electricity usage and cause equipment damage.

3. Measure amperage and voltage of blower

Improper voltage and amp draw increase operating costs and can shorten the life of the system components.

4. Measure and record temperatures and system performance factors

An accurate record of vital data can indicate potential problems and help prevent equipment breakdown.

5. Check and adjust fan switch, pilot and pilot assembly

An improperly adjusted fan switch and/or pilot assembly can result in excess energy usage and equipment malfunction.

6. Inspect and clean burners as needed

Dirty burners can cause improper combustion reducing equipment life and increasing energy usage.

7. Inspect heat exchanger for deterioration and cracks

Heat exchangers can deteriorate and develop cracks with age. These cracks can result in dangerous carbon monoxide leakage.

8. Measure and record carbon monoxide levels

High levels of carbon monoxide can cause carbon monoxide poisoning. Testing ensures proper emission levels and can help to identify heat exchanger cracks not detectable through inspection alone.

9. Inspect gas line and flue pipe for possible leaks

This ensures proper exhaustion of toxic gases and fumes.

10. Test and calibrate thermostat

Ensures that the system starts, operates, and shuts off properly.

11. Check & clean air filter/replace at customer's option* 

A clogged filter reduces airflow, which can cause a breakdown. It can also result in dirt and other filtered residue cycling back into your home.

12. Conduct overall system assessment

This includes items such as general system configuration and ductwork/heating pipes to check for wear, damage, improper installation and other potential issues.

13. Review findings, make recommendations and discuss any concerns 

It's important that you understand the condition of your heating and cooling equipment including items that may pose either immediate or future risks. You should also understand your options regarding home comfort, energy efficiency and indoor air quality.

Boiler Only:

1. Inspect expansion tank

2. Inspect water feed valve

3. Measure and record boiler pressure and temperature

4. Check aquastat

5. Inspect low water cut-off

6. Check for backflow device

7. Inspect & oil pumps

Tune up may not be the correct avenue for your heating needs. If your heating unit is over 20-years old, it is recommended to replace with a newer product. At our evaluation, our NATE-certified technicians will give you the best recommendation based on current industry standards, overall pricing, and overall time of benefit. If the repair today will only be good for one to two years, but a new unit that will last substantially longer, we want you to have the clearest idea of available options. For additional information regarding tune-up, repair, or replacement for furnace, boiler, or any heating component, contact Expert Air today.
