8 Common Heating and Air Conditioning Problems



Common Heating and Air Conditioning Problems Sacramento Homeowners May Be Facing

Some of the common heating and air conditioning problems don’t need more than a little cleaning and adjusting here and there. Others have the potential to morph into serious problems if prompt professional attention isn’t available to resolve them quickly. Here are some of the most common heating and air conditioning problems that the experts at Gilmore Heating and Air in Sacramento have encountered over the decades.

Dirty Air Filters

One of the simplest and yet very important HVAC maintenance tasks is replacing the air filters in your home on a regular basis. When the furnace or air filter is clogged with dirt, the HVAC unit will do a lot more work to force conditioned air through that dirty filter. You would be surprised how quickly your filter can build up with debris.

That extra work done by the unit puts a strain on the system and results in a higher energy bill as well. Gilmore HVAC technicians warn that if dirty furnace filters aren’t replaced in a timely manner, the blower will be overstrained and the furnace may overheat. It is important for you to adhere to the air filter replacement schedule so you avert all the problems that can result when dirty filters stay for too long.

To get a customized filter-replacement schedule, contact Gilmore Heating and Air so that our team can assess the specific conditions in your home before recommending the best interval at which to switch out the filters. Different conditions in homes can vary from having furry pets, living in an overly dusty area, and more.

Ignition or Pilot Problems

Our friends at McQuillan Bros, an AC company in Minneapolis, explained that a defective flame sensor or burner, or even a dirty pilot can all cause the furnace ignition to malfunction. The furnace may also short cycle, lockout or perform abnormally when these problems exist. A trained Folsom HVAC service professional will be needed to check the system and identify the specific defect so that the most appropriate remedy can be implemented. Don’t delay to call Gilmore Heating and Air since the problem may escalate and necessitate HVAC replacement.

Thermostat Defects

Sacramento HVAC technicians have traced a significant number of AC problems to a malfunctioning thermostat, so it might be worthwhile for you to read the manual of your thermostat and troubleshoot any issues it may have before calling a technician for help. At Gilmore Heating and Air, we would like to keep your Folsom AC service costs minimal, so we urge you to confirm that the defect is beyond your ability to fix before you call us for help.

HVAC System Wear and Tear

The heating system has several mechanical components, any of which can malfunction. Normal wear and tear can also take a toll on the system components, such as the belts and bearings. Folsom AC service includes checking all those belts, bearings and motors to confirm that everything is as it should be.

HVAC System airflow issues, overheating or poor heating can result when the mechanical components don’t get the professional attention that they need, so make it a point to have your HVAC system tune-up completed annually by a team from Gilmore Heating and Air.
Abnormal Furnace Noises

Under normal circumstances, your furnace will emit some sounds as it is working. For this reason, the sounds that you should be concerned about are the unusual ones that develop.

For example, HVAC repair technicians in Folsom say that when a furnace starts squealing or whining, the bearings in the blower or inducer motor may be worn and are about to fail. Dirty burners and airflow problems also have the potential to trigger unusual noises.
It is prudent for you to reach out to Gilmore Heating and Air for help as soon as you hear any abnormal noises coming from your furnace. This prompt action will address the problem before it gets worse and compels you to replace your HVAC unit prematurely.

Tripped Breakers or Blown Fuses

When the furnace blower is working more than it should, it will draw more current than normal, or it may overheat. This may cause a fuse to blow or a circuit breaker to trip. Experienced HVAC replacement experts in Folsom say that the most common reason behind this is a dirty filter.
It is therefore imperative to check and replace a dirty filter before you reset a tripped breaker. If the breaker trips again, call Gilmore Heating and Air so that one of our professionals can take a look. Leaking ducts, blocked air registers and other issues may be the reason why the breaker is tripping repeatedly.

Dirty Evaporator or Condenser Coils

If your HVAC system hasn’t been serviced as regularly as it should, there is a high likelihood that its efficiency has dropped. As the dirt accumulates, the evaporator and condenser coils will be subjected to a higher rate of wear and tear.
One way to prevent this from happening is by shutting off the power to the outdoor unit and then using a garden hose to clean the coils. As for the indoor evaporator coil, you are better off calling an HVAC repair professional from Gilmore Heating and Air.

Water Leaks

High-efficiency furnaces and air conditioners produce condensate, and that is why these appliances have drain pipes to remove this water. If the drain lines are clogged or cracked, water will leak from the furnace or AC.

You can keep these drain lines clean and free from clogs by periodically running bleach through them. However, experienced HVAC replacement technicians caution that not all water leaks can be attributed to clogged or damaged drain lines. Water leaks may also result from a defect in the evaporator, the heat exchanger drain pan, or even the collector box. A Folsom AC service professional can take a look and ensure that the leak is traced to its source and is fixed before the AC and your home suffers water damage.

Many of the problems above can be prevented or addressed promptly if a professional services the HVAC system regularly. Contact Gilmore Heating and Air if you, too, would like to benefit from a team of seasoned professionals who take pride in keeping heat furnaces and air conditioners working efficiently and reliably. We will gladly partner with you to protect your investment!

Setting Your Thermostat



How should you be Setting Your Thermostat for Maximum Energy Savings?

The temperature inside your home can quickly rise to uncomfortable levels during spring leading into summer. Especially if you have a two-story home without zoning. This can result in a spike in your monthly energy bill if you rely on your air conditioner to maintain comfortable conditions in the home. However, you may not be aware that you can adjust the setting on your thermostat in a way that keeps the home comfortable without denting your monthly utility budget. Here are a few tips the experts at Gilmore Heating and Air suggest for keeping your energy costs affordable during the hotter months of the year.

Be Careful When Setting Your Thermostat

In an ideal world, we would all leave our thermostats set to keep the temperature within the 60’s, but in reality, that would send our energy bills soaring during the hotter months of the year. Keeping the cost of air conditioning affordable requires that we adjust the thermostat to as high a level as we can tolerate so that the HVAC system doesn’t have to do so much work to keep our homes cool. Gilmore HVAC technicians say that when the difference between the thermostat temperature setting and the outdoor temperature is minimal, the load imposed upon the AC will be lower, and then energy consumption will also be lower.

Gilmore, your trusted Sacramento heating and air contractors, we recommend that you set the thermostat to 78°F in the hot months of the year and then change to 68°F during winter. These settings will ensure that keeping your home comfortable doesn’t come at a high utility cost.

Adjusting to the Higher Thermostat Settings

It can take a while for you to get used to warmer indoor temperatures, but this is an undertaking that will make a positive impact upon your budget. To help you adjust more easily to this warmer temperature, the experts at Gilmore Heating and Air suggest that you avoid adjusting the temperature all at once.

Instead, the Sacramento HVAC company suggests that you increase the setting by a degree each day. This approach will give your body a chance to take the change in stride. Actually, you may not even notice that there is a slight increase in the indoor temperature!

Upgrade to a Programmable Thermostat

Another way to enjoy maximum energy savings is by installing a programmable thermostat. These devices make it possible for you to automate the process of adjusting the temperature setting at different times of the day.

For example, as you leave for work in the morning, the thermostat temperature can be adjusted upwards since no one will be at home to require cool conditions. The thermostat can then lower the temperature setting in the evening when you are about to return so that you get home when the indoor temperature is at your desired level.

Folsom AC service professionals assure you that the energy savings that you make when you install a programmable thermostat will quickly add up and you will notice a drop in your monthly bills.

Other Ways to Keep Your Home Cool

Gilmore Heating and Air always advise its clients to use other techniques alongside the air conditioner in order to keep homes cool. The Sacramento HVAC company recommends the following:

Ceiling Fans. Having a functional ceiling fan has the potential to make a room feel cooler by about 4 degrees. This can allow you to set the thermostat higher and save on energy without sacrificing comfort.

Block the Sun. The rays from the sun can quickly heat up your home if you don’t take steps to block them. McQuillan Bros, an air conditioning company in Twin Peaks, recommends blackout curtains and blinds to limit the sun’s rays that get into the home. This will keep the interior cooler and the AC will not have a lot of work to do to keep the home cool.

Open the Windows. At night, the temperature will drop significantly even on the hottest summer days. Take advantage of this drop and turn the AC off after opening the windows. Cool air will enter and you will sleep peacefully without leaving the AC on. In the morning, close all the windows and blackout curtains or blinds so that the sun’s rays are kept out during the day.

Install A Whole House Fan. If you have a two-story home without proper zoning then you may want to consider a whole house fan. Now is a great time to install one before the weather heats up.

The heat can reach unbearable levels during summer in Sacramento and you may think that cranking up your Air Conditioner is the only way to stay comfortable. However, as the recommendations above indicate, it is possible to stay comfortable without seeing your energy bill go through the roof. Contact Gilmore Heating and Air for HVAC repair if a defect is compromising the ability of your home AC system to keep your home cool, or if the unit needs a tune-up to keep it working at its best.

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.
