Why Does My Heater Come on When-System-Is-Set-to-Cool

Why Does My Heater Come on When System Is Set to Cool?

Noticed a sudden spike in your electricity bill? Or maybe your air conditioning runs for extended periods of time without cooling the house?

If so, you might be experiencing a malfunctioning HVAC system. More specifically, your system’s heater is turning on even though the air conditioner is set to “cool.”

What is causing your heater to activate? Electrical issues within your central AC unit are the most likely causes of your heater turning on when it shouldn’t. Shorted wiring, faulty electronics in your furnace, or an electrical problem with your thermostat, for instance, could all explain the issue.

Bottom line, when you suspect your heater is turning on improperly, contact an HVAC specialist. Working with live wires and electrical components can be very dangerous. But the good news: This issue can typically be reversed with a quick repair.

3 Air Conditioner Issues that Can Cause Your Heater to Turn On

One of the quickest fixes for this problem: Check to see if your thermostat is set to “cool.” It sounds overly simple, but you’d be surprised how easy it is to change settings accidentally.

If your air conditioner is, in fact, set to chill, a range of issues could be triggering the heater to turn on. The most common include:

  1.   A Faulty Thermostat

Most solutions for this problem require the expertise of an HVAC technician. But you can examine your system’s thermostat. If the thermostat has lost power, this could be the source of your problem, for example.

If your thermostat is battery powered, try changing the battery. Also, if you see a blank screen, check to see if a breaker has tripped. Worst case scenario, the thermostat is defective, in which case, you’d need to have the thermostat replaced.

  1. Thermostat Connection Is Faulty

The thermostat’s connection to the furnace and AC unit may become disconnected. Or the wiring from the thermostat to the units could short out.

In other words, your thermostat may be in “cool” mode, but their furnace and AC unit have no way of knowing that. This can trigger the heater to turn on. These shorts can be caused for some reasons. For example, water damage and even rodents can both cause a short. Ultimately, a heating and cooling expert can help you restore the connection.

  1. Electrical Problems at the Furnace

Your AC and heater work in close cooperation together. In fact, even during summer, the blower within your furnace is responsible for circulating cold air throughout the home.

Inside the furnace though, there’s a complex network of wires and circuit boards. Over time, or due to water damage, these boards can malfunction and short out. And that’s a common cause of the heater issue.

In a nutshell, the furnace’s motherboard tells it exactly what to do. When it’s not properly working, the “cooling signals” the furnace receives from the AC unit and thermostat can’t be properly understood – which can trigger the heater on.

Contacting a Heating and Cooling Company to Restore Your AC System

There’s nothing quite as frustrating as a malfunctioning HVAC system. But the good news is that most HVAC problems tend to have relatively quick and low-cost solutions.

In the case of a heater that’s turning on, the simplest fix might be changing batteries in your thermostat or resetting a tripped breaker. Even more complex solutions like a circuit board replacement or wiring restoration can be finished quickly and easily.

Bottom line, if you’re experiencing this problem, contact a heating and cooling specialist. A technician will be able to diagnose the cause quickly, and get your AC system up and running in no time.

Why Doesn’t My AC Unit Come with a Dehumidifier?

Your air conditioner is cracking, but the air in your home still feels clammy. This shouldn’t be happening right? Well, this all-too-common problem tends to be the result of high levels of humidity in the air in your home.  

Here’s why this happens: Your AC acts as a natural dehumidifier. During the air cooling process, moisture is collected from the air, condensed on coils, and then drained away.

But in areas with high levels of relative humidity, the air conditioner doesn’t dehumidify the air fast enough, and the result is that wet, cold air. Fortunately, there are a variety of routes homeowners can take to dehumidify interior spaces.

Solutions for Dehumidifying the Home

You can remedy the problem by running your AC for longer periods of time, but this solution is costly. Your home’s heating and cooling costs will quickly increase.

A better option: Standalone dehumidifiers. Independent units are designed to focus only on dehumidification – and they’re much less costly to operate and much more efficient than air conditioners.

In particular, you have two options:

  • Whole-Home Dehumidifiers: Whole home dehumidifiers tie into your existing HVAC system. These units are designed to dehumidify every room in the home. Mostly, they collect air from vents within each room, and this air is sent to the dehumidifier. They’re very versatile, as you can dehumidify the home even if you’re not running the AC. Also, just like AC units, whole house dehumidifiers are available in a wide range of sizes.
  • Portable Dehumidifiers: Portable units, on the other hand, work similar to whole-home dehumidifiers. These are small, single room units that plug into the wall. Unlike whole home dehumidifiers, though, portable units collect the excess moisture in a pan in the bottom of the unit (whereas whole house units tie into drains). There are portable dehumidifiers for large rooms and spaces, as well as small units available for studio apartments and bathrooms.

A Key Benefit of Dehumidifiers. In addition to dehumidification, standalone units also act as air purifiers. As they remove moisture from the air, they filter out allergens, dust, and mites from the air. This is one reason many people install them in addition to a central air unit.

Does Your Home Need a Dehumidifier?

If you’re unsure if your home needs a dehumidifier, it’s best to contact an HVAC specialist. HVAC companies can help you determine the relative humidity of your home, and if it’s in the range of 50-60 percent, a dehumidifier might be necessary.

Plus, HVAC companies can also help you correctly size your AC unit. An oversized AC unit is a No. 1 cause of high humidity in the home. Because the unit is too large, it cools the home too quickly, before the AC can dehumidify the space. If this is the problem, right-sizing your unit might be the best option for your moisture problem.

Ultimately, a dehumidifier can save you from costly damage caused by high levels of humidity in the home. When the home’s relative humidity reaches about 55-60 percent, you might experience issues like:

  • Mold and mildew
  • Conditions for dust mites
  • Allergies, asthma and other respiratory conditions can be exacerbated
  • Ruined furniture
  • Clammy and stuffy indoor air

 

Don’t settle for swamp-like air in the home. Install a whole house dehumidifier and zap the problem. Comfort Pro offers a range of solutions for home dehumidification. Contact us today to learn more about your options.

IoT and HVAC Technology: Should I Buy a Smart Thermostat?

Your home’s HVAC system relies on various components to keep the home feeling comfortable throughout the year, and one of the most important is the thermostat. Without a proper thermostat, your air conditioner would run and run, and never know when to turn off.

That’s what the thermostat helps to do; it regulates your HVAC system. But how does it do that?

In the simplest terms, a thermostat for home heating and cooling works like a thermometer. It gauges the interior temperature of your home. Yet, the thermostat also serves the function of telling your heating or cooling system when to turn off. Thermostats are hardwired to the HVAC unit’s airhandling system or furnace. Therefore, you select a temperature, and when the air conditioning system has lowered temperatures to that point, the HVAC system cycles off.

Thermostats have come a long way in the last decade. Today, smart thermostats have become the norm, replacing standard programmable thermostats. Smart thermostats offer a number of benefits for homeowners, including web and mobile integration, sensor technology and mobile programming, and by optimizing your home’s heating and cooling, smart thermostats have the ability to help reduce your HVAC costs.

Smart Thermostats vs Programmable Thermostats

In the last decade, programmable thermostats have become commonplace in modern HVAC systems. Essentially, a programmable thermostat allows homeowners to set perimeters for the unit. For instance, you might program in different settings during the evening or while you’re away from work.

You can also add in preset preferences for the thermostat, i.e. an away setting. Smart thermostats, on the other hand, are like programmable thermostats on steroids; they add in a range of advanced capabilities.

Most importantly, a smart thermostat, like many home automation technologies, can be accessed via the web. A smart thermostat connects to your home’s Wi-Fi network, and homeowners can then access the thermostat via a mobile app or desktop app, which has been connected to the device. Therefore, you could be on vacation in Fuji, but you’d still have the ability to turn off, raise or lower your thermostat settings. Yet, in addition to remote connectivity, smart thermostats offer a range of additional features.

Key Benefits of Smart Thermostats

A smart thermostat for home heating and cooling actually “learns” about the environment around it. Therefore, it can automate setting changes, which can help you lower your home HVAC costs. A few beneficial features include:

  •  Algorithmic learning: Smart thermostats “learn” about your heating and cooling preferences and automatically adjust settings. For example, a smart thermostat might learn you’ve changed your schedule, heading into work an hour later, and revise its away-mode scheduling accordingly.
  • Reporting: With smart thermostats, you can access real-time and historical data about your system. For example, a smart thermostat allows you to view real-time energy consumption estimates, as well as monthly, yearly or quarterly data. Want to see how much energy you used last winter? That data is readily available from your thermostat’s dashboard.
  • Remote Sensing + Geofencing: Most smart thermostats have advanced sensors that can detect when you’re in the home. If you get home early from work or stay home sick, the thermostat will adjust accordingly. Additionally, the smart thermostat offers geo-fencing capabilities, meaning it can sense how close your smartphone is to the home. Therefore, you might set a preference to switch from home to away mode if your phone was more than 7 miles from the thermostat. That way, if you’ll be away for longer (signalled by being 7 miles or more from home), your thermostat can adjust.
  • Auto Environmental Adjustments: Is today a little more humid than usual? Are you in the middle of a winter cold snap? In these types of situations, you’d likely adjust your thermostat settings manually. Smart thermostats, though, have the ability to detect these variations and adjust settings automatically. This can help you avoid having to crank the thermostat in any of these situations, which can increase run costs.
  • Home Automation Integration: Many of today’s smart thermostats can be integrated with other home automation systems, like automated lighting or appliance systems. Therefore, all of your home automation tools can be accessed from the same dashboard.

Is a Smart Thermostat Worth It?

Standard thermostat units are usually reasonably priced.  Smart thermostats, on the other hand, do increase upfront costs.  That certainly might discourage some homeowners, but remember, they can help you save on heating and cooling costs.

How exactly do they cut costs? By learning about your preferences, Nest thermostats can limit the run time of your HVAC systems. For example, the makers of the Nest thermostat estimate that heating savings are about 10-12% and cooling savings are about 15% compared to a standard programmable unit.

Additionally, you receive more control, with the ability to the access the system from anywhere in the world with a Wi-Fi connection. And you can completely customize your preferences. Therefore, the customizability and the cost savings are the two biggest reasons why you might consider a smart thermostat.

How Does Your Attic’s Ventilation Affect Your Energy Bill?

Attic ventilation plays an important role in maintaining a comfortable environment in the home. In fact, problems like mold and mildew and hot attic temperatures in summer can all be offset by adequate attic ventilation.

In winter, for instance, attic vents help to remove moisture from the home. This ensures problems like mold and mildew are avoided.

Yet, in summer, the attic ventilation helps to keep attic temperatures down. And that can result in real energy cost savings.

Here’s why: The summer sun beats down on the roof of your home, pushing attic temperatures over 120 degrees. This super-hot air eventually radiates into the living space, resulting in warmer interior temperatures. Ultimately, you’ll have to run your air conditioning unit longer to offset this unwanted heat gain.

How Does Attic Ventilation Work?

If you’ve ever had to retrieve something from the attic in August, you know it gets hot up there – very hot. Fortunately, your home’s insulation prevents a lot of this heat from seeping into the home. Yet, on the hottest days of the year, insulation alone isn’t enough.

Proper ventilation helps to offset the stress that’s put on the insulation.  Basically, attic ventilation systems facilitate air circulation in the attic. Air intake and exhaust vents generate a natural flow of air – cooler air in via the intakes, warm air out via the exhaust vents – that helps to push the super-heated air up and out of the attic.

What Types of Attic Vents Are Available?

Attic vents are necessary for creating a circulation flow of air within the attic. In terms of exhaust, there is a range of options available; the most common include:

  • Power Vents: Power vents, sometimes called PAVs, resemble box vents, but they have an electric or solar-powered fan within that help to draw moisture and hot air out of the attic. The most advanced PAVs have thermostats and humidity detectors that trigger them on.
  • Ridge Vents: Ridge vents sit along the length of the roof’s horizontal ridges. An advantage: Ridge vents help to prevent hot and cool spots in the attic; creating a more even cooling effect.

What Role Do Attic Fans Play in Ventilation?

In addition to vents, your attic’s ventilation system can also benefit from fans. Yet, there are a few different types, each offer different benefits. If you want to install an attic fan, the two most common types are:

  • Whole Home Fans: A whole house fan can greatly reduce your cooling costs. Essentially, this type of fan is fitted in the attic, and they’re meant to be operated at night when temperatures have cooled. Most whole home fans are floor-mounted over a central hallway within the home. They require windows on the lower floors to be opened. When turned on, the fan draws cool air through the windows, up and into the attic, helping to push warm air out of the attic. Whole house fans energy requirements are just 10-15 percent of what you could expect from the A/C unit.
  • Attic Ventilation Fans: Attic ventilation fans are typically mounted to an exterior wall in the attic. This type of system blows hot air out of the attic, but it can have a negative effect. If the home is not properly insulated, a ventilator fan can actually draw cool air out of the home, resulting in an increased cooling load.

Improving Attic Ventilation for Cost Savings

Ultimately, improving your attic’s ventilation can have a net positive effect on your cooling bill. But attic ventilation requires a balance. Too many attic vents can cause temperature fluctuations in cold weather months, and too little venting will not do enough to dissipate heat in the summer.

The best advice: Consult with an HVAC specialist. A specialist will help you choose the right type of attic venting system for your roof, they can help you maximize your energy savings, and will ensure that the venting systems are properly placed and installed.

Take a look at some tips on proper attic ventilation from Mr. Roof.

3 Ways to Make Sure Pests Don’t Enter Through Your HVAC

Pests enter your home through numerous pathways. Some are obvious like leaky windows or doors. Yet, one that’s often overlooked is your home’s HVAC system. Gaps and holes in your HVAC system offer convenient access for pests like stink bugs, silverfish, and rodents. But what can you do to ensure your HVAC is protected?

Fortunately, pest-proofing your HVAC system doesn’t require costly investments. A few minor maintenance tasks, regular inspections, cleaning and occasional pest prevention will help you avoid a full-blown infestation.

HVAC Pests: Why Prevention Is Best

From foul odors to costly damage, rodents, insects, and small animals can do a lot of damage to your home in a small amount of time. By taking regular abatement measures, you can prevent damage from occurring. What types of problems do they cause? Here are a few of the most common:

  • Home and equipment damage: Pests can cause significant damage to your home. Termites, for example, can destroy wood structures, leading to thousands of dollars in repairs. When it comes to your HVAC, damage occurs in a few ways. For one, pests love to move into your outdoor air conditioning unit. An A/C infestation can cause performance issues and even failure. Inside, pests can damage or eat through ductwork and seals.
  • Air quality issues: An infestation can affect your health by diminishing interior air quality. Odors, pesticides, allergens and pest debris can all infect your home’s air quality.

HVAC Pest Prevention Measures

A few specific pest abatement measures can help protect your HVAC system long-term. In particular, keep a close eye on areas where pests can enter your HVAC system: Exterior vents and flues, outside equipment, and your home’s ductwork. Steps you can take to protect them include:

  1.     Seal Ducts, Vents and Flues

Exterior vents like an attic vent, soffit or dryer vent all pose potential pathways for pests. Similarly, you want to ensure that the ductwork is properly sealed. Not only will this help prevent pests infestations, it can also help you save on heating and cooling. Small gaps and cracks within the ductwork can turn into pest highways, which is particularly problematic because odors, debris and allergens carried by the pests into the ductwork will be distributed around the home.

  1.     Regular Duct Cleaning, HVAC Maintenance

Even with the best seals, pests will find ways to enter the home. One strategy to prevent larger issues is proper duct cleaning. By cleaning your ducts, you’ll remove any debris and allergens that have collected, and the HVAC cleaning professional can help you identify potential problem areas. Also, pay particular interest to the dryer vent. Dryer vent inspection or cleaning should be conducted several times per year to prevent lint build-up, which can attract rodents and insects.

Another strategy: HVAC maintenance. A seasonal tune-up for your A/C or heating equipment will ensure that pests like stink bugs haven’t infested the equipment. Bi-yearly cleanings, inspections and maintenance checks are recommended.

  1.     Clear Outdoor Units

Your air conditioning unit is exposed to the elements, and without proper protection, it can become a magnet for pests. One strategy: Ensure that the unit has been properly mounted on a raised slab and that grass and weeds are regularly cut back away from the unit.

Alternatively, you can set traps for pests local to your region. For example, in some areas, stink bugs can infest HVAC units. Setting stink bug traps around your HVAC unit can help to solve the problem. Additionally, setting stink bug traps near vents will help to limit the pest’s ability to enter the home.

 

An HVAC system that’s not properly maintained can attract problem pests. Prevent damage to your home and health by ensuring your system is properly protected. Regular duct cleaning and maintenance help to clear issues and identify problem areas. Contact us for more information today.
