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.

What is The Most Energy Efficient Heating and Cooling System?



Looking for an Energy Efficient Heating and Cooling System for your home?

When it comes to heating and cooling your home, there are a number of energy-efficient options available. So, which system ranks above the rest? To answer this question, you must first understand what these systems do.

The Basic Concept of Heating and Cooling

A heating and cooling system has a simple job: the transfer of heat. Air conditioning is transferring heat out of the building during hot weather. During the winter months, heat is being produced and transferred throughout your building via the ducts. Either way, interior temperature is altered by the displacement of hot or cold air.

Very few unified systems accomplish both heating and cooling with the same equipment. Though the systems use the same ductwork for pushing air, the methods employed for heating and cooling are usually different. Frequently, a forced air furnace works alongside an air conditioning system.

A Better Alternative

The most common configuration has just been described above. There is, however, a much more efficient option that often cuts operating costs in half. If the shear use of energy were the sole consideration, the thermal heat-pump system would easily win. This employs a coolant to transfer heat either into or out of your building. An electric pump and condensing system are also used, depending on what direction the heat is flowing.

Other systems transfer heat out during the hot months. However, to provide heat during the colder months, most other systems have to generate it somehow. A thermal heat pump uses heat already in the ground.

Energy Efficiency Does Not Mean Everything

Just because a thermal system is technically the most energy-efficient, that does not mean it is the best suited for your needs. Factors like installation cost, cost to maintain and repair, operating cost, size of your building and the local climate all play a role in choosing the best option.

3 Ways to Clean Your Heating System



Cleanliness is essential to keeping your furnace running in top condition all winter. At Gilmore Heating Air and Plumbing⁣, we recommend the following three tips to help clean your heating system

1. Change Your Air Filter

One of the simplest DIY maintenance practices you can do to maximize your air quality and your HVAC system’s efficiency is to clean the air filter. Locate your furnace’s access panel, located outside the furnace. Next, simply open the door inside and remove the filter. If the filter appears to be dirty, you will need to clean or replace it. Clean non-disposable filters with a non-toxic cleaner and water.

2. Clean Your Furnace’s Interior

Thoroughly clean the inside of your furnace by first unplugging its power cord. Next, dampen a cloth or towel with water and apply a non-toxic cleaner. Using the towel, clean the inside of the furnace, removing the fan from its location. Follow up with a vacuum then return the fan. Secure all wires and connectors, connect the power cord, and close the interior door and front panel of the furnace. If you are unsure of how to clean your furnace, contact our licensed HVAC professionals. In addition to cleanings, we do repairs, replacements, and annual routine checkups to keep your HVAC system running optimally.

3. Clean and Vacuum the Heat Exchanger Block

Start by turning off the gas, if your furnace is a gas unit, and disconnect the power cord. Next, use a toothbrush to scrub the buildup from each chamber. Using a vacuum with a narrow attachment, vacuum each chamber.

How To Optimize Your Energy Efficiency This Winter



Saving energy this winter doesn’t have to be time-consuming or expensive. In fact, there are several low-cost ways to optimize energy efficiency during the cold winter months. Here are a few:

1. Cover Your Home’s Windows

Drafty windows can reduce your home’s energy efficiency. If new windows aren’t in your budget this year, don’t worry. You can seal drafty windows by taping heavy plastic over them.

2. Reduce the Temperature on Your Hot Water Heater

Adjust your hot water heater to a warmer setting. A comfortable setting is 120 degrees. By taking this action, you can optimize your energy efficiency and prevent hot-water burns.

3. Use LED Holiday Lights

Decorating your home for the holidays can raise your electricity bills. When you decorate your home with lights, be sure to invest in LED lights. For the most savings, be sure to buy lights that are certified by ENERGY STAR.

4. Use Your Wood-Burning Fireplace

A wood-burning fireplace can provide heat for a fraction of the cost of raising your thermostat. Be sure to open the fireplace dampers and close the doors in the room.

5. Adjust Your Thermostat

It feels good to come home to a warm environment, but keeping your home warm all day can result in an expensive utility bill. When you’re not at home, reduce the temperature on your thermostat.

6. Seal Your Fireplace

Like windows, fireplaces can get drafty. This is especially true if your fireplace isn’t sealed properly. Inspect your fireplace for drafts. Seal or caulk any areas that cause heat to escape from your home.

7. Clean and Maintain Your Heating System

A dirty heating system can adversely affect your home’s energy efficiency. Optimize your heating system by replacing your filters as needed. To maintain your heating system, schedule an appointment with Gilmore Heating, Air, and Plumbing⁣.

Our technicians at Gilmore Heating, Air, and Plumbing⁣ can help you optimize your energy efficiency. Services include professional furnace repair and furnace tune-ups. Call us to schedule an appointment for one of our services in the Placerville area.

Why Change Your Home Air Filters



It can be easy to forget about your air filters and the important role that they play in your home because they’re often out of sight, which makes them out of mind. Unfortunately, many issues can develop if the filters aren’t replaced once they’ve reached the end of their lifespan. If you want to maintain your home properly and protect your health, there are a few reasons you need to change your home air filters each season.

Improve the Air Quality

One of the main reasons to change your air filters every few months is to improve the air quality of your home. The filters are designed to collect pet dander, pollen, contaminants, dust, and other debris.

Over time, the filters can become clogged with these particles. By replacing the product regularly, any small particles will be collected rather than recirculated into the building as the HVAC system is in use.

Reduce Your Energy Usage

A new air filter can prevent the HVAC system from working too hard because it won’t be clogged. By replacing the filter, it will allow the appliance to have better airflow and will reduce the energy usage in the building. By reducing your energy usage, you can recoup the costs of the filters by having a lower bill each month.

Save Money on Repairs

Repairs are common on HVAC systems that have dirty filters due to a lack of airflow. This can lead to excess wear and damage to the parts. With a new filter, you can reduce the risk of damage that can occur and avoid having to spend more money on fixing issues to keep the appliance running.

Our technicians are qualified to provide you with tailored solutions to your specific needs when it comes to changing your air filters. We also offer a full range of additional heating and air conditioning services for residents of Placerville, CA, and the surrounding area. Call us at Gilmore Heating Air and Plumbing⁣ today for more information on the different types of filters that we have available for our customers.

Signs of Problems With Your Furnace



No one wants to deal with a furnace that is not heating. Since it never happens at a convenient time, heating failures can lead to expensive emergency repair bills. If you pay attention, you may find that your furnace has been giving you signs of a necessary repair.

Strange Smells

When your heating system kicks on for the first time in the season, you may notice the slightly charred smell of a year’s worth of dust that has made its way around the burner. That smell should only last for a cycle or two. If you notice any strange odors when your system is running, it is time to bring in a professional to have a look.

Loud Noises

Every heating system makes some amount of noise as the burner ignites or blower fans turn. However, when a system begins to fail, you may hear the scraping sound of a misaligned blower fan, the high-pitched whining of a loose motor belt, or the rattle of loose screws. Pay special attention if your system starts with a bang. This may indicate that the burner ignition is not timed correctly.

Rising Heating Bills

If the cost of your heating bill is an unpleasant surprise, it may mean that your heating system is not burning fuel efficiently. If you have a gas furnace, be sure to examine the pilot light. A burner that is running properly will burn with a blue flame. A yellow pilot light not only indicates inefficient burning, but it may also indicate excess production of carbon monoxide. If you see yellow, be sure to have your system checked by a professional right away.

Checking Your Home for Air Leaks



Air leaks in your home can have many sources, including a crack in the foundation, a hole in the attic or a door that doesn’t sit quite right against the jamb. While these leaks are certainly a kind of natural ventilation, they aren’t ideal. You probably heated or cooled that escaping air at great expense, and these leaks just make your cooling or heating system work harder.

Where Are Air Leaks in a Home Most Common?

Gilmore Heating Air and Plumbing⁣ has been helping customers throughout the Greater Sacramento area achieve proper ventilation since 1979. We’ve found that many people believe windows and doors are the main culprits when it comes to air leaks. Statistically, however, the worst culprits are floors, walls, and ceilings. The next-worst offender is the ductwork.

Ductwork and Air Leaks

Inspecting, maintaining and cleaning your air ducts is important. It helps to keep your energy efficiency high and your indoor air pollution low. Energy Star estimates that about 20 percent of the air that moves through average ductwork is lost due to leaks. Leaks can be caused by shoddy installation but can also manifest over time due to wear and tear.

How Do You Check for Air Leaks in a Home?

The best way to check for air leaks in a home is to schedule a professional home energy audit. This will include a comprehensive examination of problem areas: floors, walls, ceilings, ducts, fireplaces, plumbing penetrations, doors, windows, fans, vents and more. If you’d like to conduct your own testing, a common way to do this is to burn incense after having shut down the heating and cooling system as well as any independent fans, exhausts and so forth. Note the spots that cause the smoke to drift.
