AirConditioning Repairs Fixes Your HVAC Unit That Aren’t Too Expensive

Airconditioning Repairs

Airconditioning Repairs You expect a burst of cool or warm air from the vents when you switch on the thermostat. If this doesn’t happen, your initial inclination could be to look up HVAC repair firms on your phone. Not so fast: You can make small repairs to your HVAC system yourself, saving time and money over having a professional come to your home.

What You’ll Require

Tools / Equipment

Screwdriver
Drill with no cord
Lighter in the kitchen
Shop vacuum
Flashlight

Materials

Air filter replacement
Thermostat wire, 18/5

Directions

If The Air Conditioner Is Blowing Warm Or Hot Air,

1. Potential Causes

The air conditioner should blow cold air, not warm or hot air, when it is adjusted to the correct temperature. It’s possible that your system’s air filter is clogged. The easiest and first thing to check is the filter. Otherwise, the condensate drain line may not be flowing water properly, or the refrigerant level may be low or leaking.

2. Potential Solutions

Dirty Air Filter: Changing your HVAC system’s air filters should be part of your routine maintenance. The filter may become clogged if you are running late. Activities that produce dust, such as lighting a wood-burning fireplace or constructing a structure indoors, can clog filters more quickly than usual. Remove and discard the existing filter. Replace the old filter with a new one. Make that the filter is pointing in the right direction, as shown by the arrows.
Drain Line for Condensate: To access the line and condensate drip pan, remove the service panel. Vent after removing the threaded plug. Clean out the drain with a shop vacuum set to wet mode. Locate the drain line’s end-point outside and use the shop vacuum to remove any obstacles.
Refrigerant: Call an HVAC expert if you feel the refrigerant is low or leaking. A leak test will be performed by the technician. They can patch leaks if they are identified. The technician can also recharge the refrigerant if it needs to be done. You should not attempt to replenish the refrigerant on your own.

If The Air Coming Out Of The Furnace Is Cool Or Cold,

1. Potential Causes

If your HVAC system’s furnace isn’t providing warm air, it’s always a cause for concern. The airflow may be slowed because the filter is clogged. The warm air will have already cooled by the time it reaches the vents. If the filter isn’t the problem, the pilot light may have gone out. Alternatively, the furnace may heat up but the blower isn’t working, preventing hot air from reaching the vents.

2. Potential Solutions

Furnace filter: Replace the furnace filter. For best airflow, make sure it’s pointed in the right direction.
Relighting the pilot light At the thermostat, turn off the furnace. Locate the pilot light at the furnace’s bottom. Wait three minutes after switching it to the OFF position. To use the automated piezoelectric lighter, set the knob to PILOT and press the knob. If it doesn’t have a piezoelectric lighter, use a kitchen lighter to light the pilot.
Blower: Blowers in gas furnaces are powered by electricity. Even if the gas is turned on, the blower may not function properly. If a circuit breaker has tripped, check the electric service panel. If this is the case, reset the breaker by flipping it backward (toward the box’s outer edge), then forward until it clicks into place.

If the Thermostat Doesn’t Work Properly

1. Potential Causes

Nothing else in the HVAC system will work properly if the thermostat isn’t working properly. The thermostat is the system’s control centre. Power is required for all thermostats. Batteries, a low-voltage cable, or both can be used to power thermostats. The thermostat will not work if there is a power outage. Thermostats aren’t usually at the best location. It’s possible that yours was placed in direct sunlight or near a cool, draughty area.

2. Potential Solutions

Battery Capacity: If your thermostat has a battery, the first thing you should do is replace it with a new one.
Power at Low Voltage: Remove the front plate and turn out the screws holding the thermostat to the wall to see if it has a low voltage wire. To check that all of the wires are connected, gently pull the thermostat away from the wall. Unnecessary wires are frequently present, and their ends may still be coated in plastic. It’s cheap to replace the 18/5 thermostat wire, but threading it from the HVAC system to your thermostat can be difficult.
Problems with Placement: Short of relocating the thermostat, you can alter the conditions that are causing the thermostat to malfunction, such as blocking sunlight with curtains.

If Your Heat Pump Or Furnace Never Turns Off, It’s Time To Replace It.

1. Potential Causes

The heat pump or furnace may be compelled to run constantly to keep up with the demands if the house is inadequately insulated. It’s also possible that the exterior unit is frosted over or has a snowdrift against it, obstructing the vents. Another reason could be that the unit is overworked due to the cold return air. When the interior air is reintroduced to the device, it should be warm. The unit has to work harder to keep up if the air is too chilly.

2. Potential Solutions

Insulation: In certain cases, the house’s walls and ceilings are so poorly insulated that inside temperatures plummet in the winter. The remedy is to insulate the walls, either by removing drywall from the inside and installing roll or batt fibreglass insulation, or by insulating closed walls with cellulose insulation. Insulation batts can be installed between the joists or cellulose insulation can be blown into the attic.
Whether there is ice or snow on the unit: Remove ice off the top of the external unit with a scraper. Brushes snow off the roof and shovels snowdrifts away.
Air Return: A disconnected or leaking return air vent that pulls chilly air from the attic is a possible culprit. While the unit is running, inspect the ducting. The duct can sometimes be accessed from the attic. Locate the duct and examine it with a flashlight for any signs of leaking, either audible or visible.

3. Symptoms of a Leaking Duct

- The duct connection is loose.
- conduits with holes
- Flexible ducts that have been crushed
- Duct tape is either missing or isn’t holding.
- When the system is turned on, it makes a whistling sound.

If There Isn’t Enough Airflow

1. Potential Causes

By pumping air out of the system, through ducts, and into your home via vents, HVAC systems create a loop. The same air is sucked back into the unit through separate return vents and ducts for re-heating or re-cooling.
Any of the loop’s vents could be closed or obstructed. The grating or the first few feet of the duct could be blocked by dust, pet hair, or other material. The dampers, which are metal plates that open and close to limit the quantity of air that passes through the ducts, could be another little-known reason of poor airflow.

2. Potential Solutions

Vents: Turn out the screws that hold the vents (including the return vent) in place with the cordless drill. Use a shop vacuum to clean them. While you’ll need special equipment to clean the entire house, you can clean the first 3 or 4 feet by inserting the hose into the duct at each vent point.
Damper: Dampers can be found close to your unit. They’re near the duct system’s branches. The dampers are sometimes adjusted with a screwdriver or by physically turning a lever. If it’s a lever, you’ll likely have to rotate it till the handle is parallel to the ducts. This fully extends the damper’s range of motion.
