Quality HVAC Services | Air Conditioning Repair Plano, TX

When cooler temperatures begin to arrive in the fall we begin to experience an increased demand for our quality HVAC services, and emergency heating and air conditioning repair in Plano, TX start to fill the schedule. Calls are often for due to the emergency of a family with no heat.

A large number of these emergencies are preventable, or would have been less costly with routine professional maintenance and timely heating and air conditioning repair in Plano, TX. Pre-season maintenance by a certified HVAC professional doesn’t guarantee the system won’t experience problems, though it will ensure it is operating properly and safely. Routine maintenance reduces the likelihood of furnace failure, and the number of breakdowns. The best option is to be prepared for extreme weather.

Homeowners can help reduce problems by providing filter changes as recommended by the manufacturer. Dirty filters diminish furnace efficiency, while the strain on the system will cause premature wear, dangerous overheating and failure of the affected components.

The frequency of filter changes will depend upon the type of filter used, the conditions in the home affecting how quickly it becomes dirty, and the manufacturer’s recommendation. As a general rule, if you use the cheap blue fiberglass filters it should be changed monthly, whereas pleated filters can be changed every three months when operating under normal conditions. A good rule of thumb is to check the filter monthly, and change it if required.

Back-up Heat

When extreme weather hits, the demand for heating and air conditioning repair in Plano, TX can back up quickly. Having a safe source of back up heat will ensure your family stays warm while waiting for help to arrive. An additional thought to keep in mind is that heaters tend to sell fast when extreme cold is due to arrive. Backup heat may be difficult to find when you will need it the most.

Preparing in advance will prevent being caught without backup heat while you wait for a technician to arrive to provide heating and air conditioning repair in Plano, TX. It’s a good idea for homeowner’s to keep several space heaters on hand. Electric, oil filled heaters are one of the safest, reliable options available for backup heating.

For your family’s safety, never use a fossil fuel type of heater that isn’t properly vented for exhausting carbon monoxide gas to the outside of the home.

Before Scheduling Furnace Repair

So often an emergency service call is due to something as simple as a family member cut the power off and forgot about it. When the furnace won’t heat, check the following before calling for help:

  • Check the thermostat. First, ensure it is set to HEAT
  • Next ensure the fan is set to AUTO (a fan set on RUN or Manual may be the cause of your furnace blowing cold air, as the fan runs continuously)
  • Thirdly, check the temperature setting. A thermostat set to your nightly 65 degrees Farenheit won’t cut on until the temperature falls below 65. If the home temperature is 66, the heat won’t run when set on 65. Turn it up and see if the furnace will produce heat.
  • If the furnace is a gas burner check the gas meter to conform the meter hasn’t been cut off. If the utility supplier has shut the gas off they typically place a lock on the valve. Don’t assume because you paid your bill, it hasn’t been shut off, errors can occur.
  • For a propane furnace ensure the tank isn’t empty by checking its gauge.
  • Confirm the furnace breaker in the electrical panel is on.
  • Ensure the power switch on or near the furnace is on.
  • Inspect the filter. A dirty filter can cause the furnace to overheat triggering a shut-off safety feature on some units.

If the problem remains unresolved, contact us for heating and air conditioning repair in Plano, TX.

Dangers of Damaged Heating & Air Conditioning Parts | Heat Exchanger

The Dangers of a Cracked Heat Exchanger

A gas furnace can provide a low cost and efficient form of heat for your home. In the southern states, a gas furnace may utilize natural gas or propane for fuel. Both are fossil fuels, and as a consequence produce carbon monoxide. A furnace depends upon the heat exchanger to safely exhaust it through a flue to the outside of the home. When the heat exchanger develops a crack or rust, deadly carbon monoxide leaks into the home resulting in illness, and is potentially life threatening to the home’s occupants. If the furnace shuts itself off, and/or a carbon monoxide detector alarms, contact your heating and air conditioning technician for service promptly.

Causes of a Cracked Heat Exchanger

When the furnace is unable to obtain an adequate airflow, the heat exchanger overheats, potentially cracking the heat exchanger. Not even a new furnace is immune to the potential for cracks if overheated.

One common cause of an overheated heat exchanger is a dirty air filter. A clogged air filter restricts the airflow through the furnace, causing it struggle for air and resulting in the overheating of the heat exchanger, resulting in dangerous stress fractures.

Follow the manufacturer’s recommendations for filter type and frequency of filter changes. Even filters that are typically changed every three months should be checked at least once per month. Numerous causes of increased dust, such as remodeling or windy and dusty conditions can increase the need for more frequent filter changes. Ideally, the filter should be checked every two weeks and changed if necessary.

Having a furnace or heating and air conditioning system installed that is correctly sized for your home and its individual characteristics is vitally important. Bigger is not better, and an over-sized furnace is an additional cause of overheating and heat exchanger cracks. The same is true of the home’s ductwork. Improperly sized ductwork will also affect the furnace or heating and air conditioning system’s performance, and can place too much strain on HVAC equipment when improperly sized for the home or the system.

Causes of Rust in a Heat Exchanger

Rust in a heat exchanger poses another potentially dangerous problem. This situation is also caused from having a furnace too large for the home. An over-sized furnace heats the home too quickly causing the furnace to shut off in a short period of time. This results in moisture remaining in the heat exchanger rusting it from the inside. This is a problem due to an additional byproduct of combustion – water. When a furnace first runs, the effect of the flame on the cold heat exchanger causes water vapor to condense inside of it. The increased frequency of on-off cycling of an over-sized furnace increases the expansion and contraction stress placed on the heat exchanger. This in turn, makes the heat exchanger more prone to stress fractures.

Signs of a Cracked Heat Exchanger

Quite often, the first signs of a cracked heat exchanger is no heat or an alert from a carbon monoxide detector. A cracked heat exchanger allows air from the furnace blower to affect the pilot causing it to flutter or even go out. This activates a safety switch, which shuts down the furnace.

A cracked heat exchanger cannot be repaired. When a crack or rust occurs, it must be replaced or a new furnace installed. If the furnace is over-sized, replacement will not prevent the long term problem, and replacement of the furnace or heating and air conditioning system will be the ideal solution.

All the problems and dangers due to an improperly sized heating and air conditioning system or furnace can be avoided by using an experienced, qualified and reputable heating contractor such as the professionals of Garland Heating and Air Conditioning. Garland’s certified HVAC technicians serve Dallas, Plano and the surrounding areas.

Weatherize Your Home For Better Heating & Air Conditioning

Weatherize Your Home | Heating and Air Conditioning

When you weatherize your home stops air leaks, and helps to increase your comfort by providing a more consistently stable temperature. Air infiltration and the escape of conditioned air is a significant source of the loss of energy. The infiltration of outside air increases the system’s need to run and consequently the wear on your homes heating and air conditioning system.

Weatherizing the home doesn’t cost a lot, though the savings realized can be significant. Use the following simple, inexpensive tips to reduce energy consumption and save on heating and air conditioning costs, and reduce wear and tear on your HVAC system, while increasing the home’s comfort level.

Insulate outlets and light switches

Installing electrical outlet foam sealers to outlets and switches will block the infiltration of outdoor air. Air leaks from basements and attics can travel through interior walls, creating drafts from plate covers. Remove the plate cover and check for unsealed spaces around the outlet box. Use expanding spray foam insulating product to fill open areas around the exterior perimeter of the outlet or a light switch box, do not use inside the box.

Weatherstrip Doors

Ill-fitting or unsealed doors can cause significant air infiltration and loss of conditioned air. Inspect your door from inside the home when the sun is shining on it, if you can see daylight it needs some attention.

First, ensure hinges, door knobs and strike plates are tight. These determine how tightly a door closes.

Inspect the door sweep at the bottom of the door; if it is worn, cracked or warped replace it. Use the same criteria to inspect the weatherstripping around the doors and replace if necessary.

Weatherstrip Windows

Inspect windows and replace worn weather stripping. One often overlooked area affecting windows is the gaps behind the window casings. Home builders often fail to insulate the space surrounding windows when they are installed. Inspection and insulation will require removing the casing and may result in damage to casings. If you are willing to risk it, use caution and go slowly to reduce damage. Be aware it may result in damage to wall paint. Expanding spray foam sealer is an easy and effective solution to gaps around windows.

One method of tightening windows and reducing drafts is to close and lock them which create a tighter seal.

Replace dryer vent

Dryer vents can be a source of cold air entering. If the vent is merely a grill replace it with a grill that will close such as the shutter style. You should be aware that lint can rapidly build up causing the shutters to remain open. Make it a habit to inspect it monthly and clean as necessary.

Roof vents

Some homes utilize open exhaust vents on the roof, which can result in air infiltration, especially when the HVAC system runs. These vents are found on the ventilation pipe for a stove hood range or bathroom exhaust fans. Consider having vents with flaps installed for these ventilation pipes. They open when the fan runs, and remain closed when they do not. This prevents incoming air infiltration or conditioned air losses, which can be a significant source of air leaks. Self-sealing vents will reduce your energy costs and the wear on the heating and air conditioning system.

Seal Holes

Inspect intrusions such as around plumbing under sinks, tubs, showers and the dryer vent. Seal gaps surrounding pipes with expanding spray foam insulation or caulking.

Remember, when the heating and air conditioning system runs, the system pulls air toward the return (where the filter is located), this can result in increased air filtration when the system runs. In the winter this allows cold air to enter which then must be heated by the furnace. On the other hand, during the summer it pulls hot, humid air in which must be cooled by the air conditioner and dehumidified.
