5 Causes of One Hot Room in the House



5 Causes of One Hot Room in the House

One of the HVAC problems that we often get at Gilmore Heating and Air are complaints about having one hot room in the house even when the AC is turned on. Before this problem can be fixed, you’ll need to find the source of the problem. Here are the common causes of one hot room in the house.

Undersized HVAC Equipment

Over the years, the load that your Sacramento HVAC system is tasked with handling can change as different rooms evolve. For example, when you convert a bedroom into a home office, and you install electrical equipment there, the heat generated by the equipment may be too much.

Residential air conditioning company in Placerville says that as a system becomes undersized for the load, it has to bear, the furthest rooms from the air handlers will be the first victims to show insufficient cooling. Headwaters Construction Inc, a Sacramento commercial construction company, agrees that undersized HVAC equipment can play a big factor in properly cooling your space.

Gilmore Heating and Air techs will recommend the best option for you. For example, we may advise you to use ceiling fans or improve the insulation of your home. However, some cases may only be remedied by getting a bigger sized AC selected and installed by your Sacramento HVAC replacement technicians.

Warm Air Rising to Upper Floors

As you may know, cool air is denser than warm air. Consequently, warm air tends to rise while cool air occupies the lowest level in a conditioned space. This may explain why the rooms on the upper floor of your home are warmer than the rooms downstairs.

Residential AC service Placerville professionals can help to fix such a situation. For example, adjusting the air vents or dampers can deliver more conditioned air upstairs. Boosting attic insulation can also help, just as adding a ventilation fan in the attic can extract warm air. If all these conservative options don’t yield results, professionals may suggest that you install an HVAC system solely for the upper floor of your home.

Leaking Ducts

It is also possible that one room in your home is always hot because the ductwork is leaking. Such a leakage not only wastes energy but also creates room for other problems.

Fortunately, Gilmore Heating and Air have effective tools to test and establish which ducts are leaking. Thereafter, our residential AC maintenance personnel will seal and insulate the ductwork properly. 

Improperly Positioned Thermostat

The location of your thermostat will have a great bearing on the degree of comfort in your home. For example, if the thermostat is located near a heat source (behind an oven, for example), the sensor will get an inaccurate reading of the temperature inside the home. Therefore, you will get uneven cooling in the house.

Other unsuitable locations for a thermostat include close to exterior doors that are frequently opened. Your home’s thermostat shouldn’t be close to windows where direct sunlight reaches it.

When you complain about having a hot room in your house, Sacramento HVAC personnel will determine whether the location of the thermostat is ideal, in addition to checking for other possible causes. If the placement of the thermostat isn’t appropriate, we will relocate the device.

Dampers and Vents That Need to Be Adjusted

There has to be a balance in an HVAC system if it is to deliver satisfactory cooling throughout a building. However, renovations and alterations in the way rooms are used can throw this balance off.

For example, when a wall is removed during a remodel, the dampers and vents have to be adjusted to address this alteration. Otherwise, the bigger space created will not get sufficient cooling. 

As you can see, several factors can cause one room in your home to be hot. The best way to determine the cause behind this is by contacting your local HVAC company, Gilmore Heating, Air, and Plumbing. Our experienced professionals can fix the problem.

 

Why Is My Heat Pump Blowing Cold Air?



My Heat Pump is Blowing Cold Air

Hey Sacramento, it’s still cold and rainy. Amid all of the other stuff happening in the world, you might be hit with the fact that your heat pump is blowing cold air. At Gilmore, we’re ready to help you diagnose and fix the issue. Discover the likely explanation of what could be happening to your heat pump and what could be the cause. Use this information to make an informed decision on whether or not you need to call one of our skilled HVAC repair technicians to help. Gilmore Heating and Air have got you covered!

As you may be aware, a heat pump draws heat from outdoors and brings it indoors. Here lies a possible explanation about why cold air is coming from your heat pump. You see, the temperature outside may drop significantly, especially at night, and this could reduce the temperature of the heated air coming from the vents in your home.

For example, it isn’t uncommon for the temperature outside to drop to 40°F on cold nights in Sacramento and even colder up in the foothills. Even at that temperature, your heat pump will still be able to supply air at 80-85°F, a much higher degree of warmth than what the situation is outside. However, our normal body temperature hovers around 98.6°F, so the air which is at 85°F will appear to be cold since it is at a lower temperature than our body temperature.

In order to confirm that this is what you may be experiencing, the Sacramento HVAC professionals at Gilmore Heating and Air recommend that you take note of the temperature reading on the thermostat of your HVAC system and then check back after half an hour.

If you observe that the thermostat is displaying a higher reading, then your heat pump is working. This means that there is no reason to worry about the “cold air” that you thought the heat pump was releasing into your home.

Possible Explanation #2: The Heat Pump Could Be in Defrost Mode

Sacramento HVAC experts explain that heat pumps are designed to switch to defrost mode from time to time when the temperature drops. This mode entails a temporal change from heating mode to cooling mode to allow warm air to circulate over the outdoor coils. This safeguards the pumps from freezing due to any frost that could have built upon them.

This defrost cycle may run for a minute or two, and this narrow window could coincide with the time when you check and observe that the vents in your home are discharging cold air. Folsom AC service technicians have confessed that a number of service calls that they get fall in this category where the heat pump was okay and didn’t need any professional attention.

To confirm that the cold air from the vents isn’t something to worry about, McQuillan Bros, the best AC Company in Minneapolis, recommend that you go and observe whether the fan on the outdoor unit of the heat pump is running. If the fan isn’t running and you can see puffs of steam coming from it, then you have your confirmation that the heat pump is in defrost mode. If still in doubt and you want a second opinion on the matter, contact Gilmore Heating and Air so that one of our experienced HVAC repair professionals can take a look and allay your fears.

Possible Explanation #3: Something Could Indeed Be Wrong with the Heat Pump

If you notice that your heat pump is blowing cold air into your home and this has lasted for more than the few minutes needed to run a defrost cycle, there is a possibility that something may be amiss with that unit. This means that a professional from Gilmore Heating and Air may need to take a look. Here are some of the common defects that may cause the heat pump in your Folsom home to blow cold air:

Refrigerant Leaks.

When the heat pump doesn’t have the required quantity of refrigerant, the unit will be unable to draw sufficient heat from outside and bring it indoors. A refrigerant leak is a serious problem that needs to be addressed promptly by a Folsom AC service professional from Gilmore Heating and Air, so contact us immediately if you suspect a refrigerant leak may be the culprit.

A Defective Reversing Valve.

The reversing valve in a heat pump makes it possible for the unit to switch from cooling mode to heating mode by reversing the direction of the refrigerant. If this valve malfunctions, then the heat pump will run continuously in the cooling mode. This may explain why you are noticing cold air coming from the vents in your home at a time when you expect warm air. We strongly advise that you leave this issue in the capable hands of our trained HVAC repair professionals since the complexities of this component tend to be beyond a DIY heat pump repair.

The Outdoor HVAC Unit is Frozen.

Despite running several defrost cycles, the outdoor unit could remain frozen and cause the heat pump to blow cold air into your home. A number of defects in that outdoor unit could be responsible for the inability of the unit to defrost, so it is best to invite an experienced Gilmore HVAC professional to check the unit and perform the needed repairs.

Loss of HVAC Efficiency.

Like all machines, a heat pump can gradually lose its efficiency, especially as it nears the end of its expected service life or if it hasn’t been maintained properly. Gilmore Heating and Air recommend that you have your heat pump serviced at least once annually so that it can work efficiently for longer. If your heat pump hasn’t been tuned up within the last 12 months, call a Sacramento HVAC company, such as Gilmore Heating and Air, for the needed maintenance work.

As you can see, one out of a possible three scenarios may be at play if you observe cold air coming from the heat pump in your home at a time when you expect warm air. If you aren’t getting the service that you expect from your heat pump, contact Gilmore Heating and Air. Our experienced technicians will check the unit and repair what is defective, or even advise you to consider HVAC replacement if that is a more viable long-term solution.
