Have You Been Switching Back and Forth From Heat to AC?

Many homeowners find it difficult to regulate the temperature in their homes during the Fall. You switching back & forth probably woke up this morning with a nip in the air, but temperatures are supposed to warm up  this afternoon.

During the day air conditioner may need to run, but find it may be too cool for sleeping. Many people switch back and forth between the heating and air conditioning system when spring brings warm days and cool nights.

But will this damage your HVAC system? Generally, switching back and forth between heating and air conditioning modes won't cause any problems.

However, sometimes switching back and forth can cause your system to shut off. If you "short-cycle" the air conditioner, it can cause the fuse or circuit breaker to trip for the outdoor condensing unit.

This is a mistake many people make. When the unit is in the cooling mode and the thermostat is calling for cooling, the outdoor unit is on. If you adjust your set point temperature higher to shut it off and then immediately dial the setpoint temperature lower it would call for cooling again and cause the compressor to lock-up.

The reverse is also true. Should the cooling unit finish a cycle and shut down and you immediately go to the thermostat and set it lower, the equipment will attempt to come back on but the compressor will probably lock-up because  the pressure has not equalized in the system.

When a compressor locks up during high pressure start-up conditions, it will draw a very high amp rate.This can cause a breaker or fuse to blow. Some units have built-in "Anti Short-Cycle" timers. Some digital thermostats have built-in time delays to prevent this from happening.

If your system shuts off, first try checking the fuses or breakers. You should also check the outdoor disconnect for your unit. Some have a separate breaker.

You should get in the habit of letting your thermostat set in the OFF position for at least 5 minutes after it shuts down, before starting another cycle. This allows the refrigerant pressure in the system to equalize.

Should your system shut down and you have checked the breakers or your fuses and that isn't the issue, you should then call a repairman. The problem may be more complex. 

We recommend regular HVAC maintenance to help prolong the life of your equipment. Our Fall Furnace tune up can prevent minor issues from becoming major ones.

Upgrading Your Furnace? Consider a Two-Stage Model

Posted by Ohio Heating

Sep 18, 2021 8:00:00 AM

We are often asked, "What is the difference between single-stage and two-stage furnaces?" Confused? Here are some facts that can help you understand the differences. 

How single-stage vs two-stage vs variable capacity furnaces differ:    woman confused_s

  • Single stage furnace. These furnaces always run at 100% capacity. They usually cost less, are less fairly dependable, costs of repairs tend to be low, and the efficiency is low to average.

  • Two stage furnace. The majority of the time, these run at 70% capacity, but can also run at 100% capacity. Usually moderately priced, these furnaces are less likely to breakdown, average repair costs are average, and the efficiency is low to high depending on the model.

Single-stage furnaces have a gas valve that opens at 100% capacity. If it is a 100,000 BTU per hour furnace, it is always burning at the 100,000 BTU rate, while a two-stage gas furnace has valves that can open at either about 70% or 100%. This means that the 100,000 BTU furnace can operate at 70,000 BTUs per hour or at 100,000 BTUs per hour.

Two-stage furnaces run at the low stage most of the time, which is 65% or 70% depending on the furnace model. Cycles are longer and produce lesser temperature swings of one to two degrees. Most have multi-speed or variable-speed blowers. They start blowing at a low speed until the furnace is fully hot, and then ramp up. This means that less cool air is pushed through your ducts.

The longer cycles produced by running at less-than full capacity, means air gets moved through the filter more times during the day. This results in cleaner air in your home as it helps remove more dust, debris and allergens.

If you're thinking of replacing your old furnace, you may want to consider a two-stage model.
The most efficient two-stage furnaces are 95% to 97% efficient and can provide a superior level of comfort for your home.

iWave Air Purifiers for Your Home

Posted by Ohio Heating

iWave Air Purifiers
Protect your family and improve the air you breathe!

Be ready for the coming cold and flu season. Seasonal flu and other viral epidemics occur mainly during winter, from October to March in Ohio.  There are iWave air at 10.49.02 AM precautionary measures that can be taken to limit transmission of flu and other viruses in your home. The iWave air purifier offers exceptional air cleaning by reducing pathogens, allergens, and  particles in your air.  

The iWave family of products have been proven through independent lab testing to significantly reduce a wide variety of pathogens in the breathing zone and on hard non-porous surfaces. 

iWave is an air purifying device that installs in any duct air conditioning system. When air passes over the iWave, ions produced by the device reduce pathogens, allergens, particles, smoke and odors in the air, creating a healthy environment without producing any harmful byproducts.

iWave uses patented technology, called needle-point bi-polar ionization, to create equal amounts of positive and negative ions. When these ions are injected into the air stream, they break down passing pollutants and gases into harmless compounds like oxygen, carbon dioxide, nitrogen and water vapor.

When the ions come in contact with viruses, bacteria or mold, they remove the hydrogen molecules – without them, the pathogens have no source of energy and will die. The ions also attach to allergens like pollen and other particles, causing them to band together until they are large enough to be caught by your ventilation system’s air filter.

iWave’s technology generates the same ions that nature creates with lightening, waterfalls, ocean waves, etc. Nature uses energy and shear to break apart molecules, naturally cleaning the air and producing a healthy environment. The only difference between the iWave’s technology and nature is that the iWave does it without developing harmful ozone.

You’ll find iWave’s advanced technology provides the most effective air purification method. Other common air purification technologies require ongoing maintenance with bulb/cell replacement every year or two, making the cost of ownership undesirable.

iWave air purifiers have no harmful byproducts, and most models require no ongoing maintenance and have no replacement parts. In fact, with the iWave-R’s patent-pending self-cleaning design, you can enjoy years of maintenance-free performance.

Nu-Calgon offers a three-year limited warranty on iWave products. For a valid warranty claim within three years, proof of purchase and proof of installation by a licensed HVAC or electrical contractor must be provided. See full warranty for complete details.

Available for residential and commercial usage. A number of schools, restaurants and commercial businesses across the country have installed iWave air purifiers to provide a safer environment for employees, students and customers.

Ohio Heating & Air Conditioning is a company that is not only a leader in heating and air systems, but in providing our customers the highest quality of indoor air. Our indoor air experts can diagnose and help you solve any indoor air quality issues you may have. If you would like to learn more about the iWave systems, contact Ohio Heating, at 614-863-6666.

Is Your Electric Bill High Because of Your Hot Water Heater?

Posted by Ohio Heating

Sep 2, 2021 8:59:00 AM

Your hot water heater uses a lot of energy. The second biggest user of electricity in your home is your water heating system. On average 18% of your electricity costs are generated by your hot water system, according to the U.S. Department of Energy. Can you save money on your electric bill without resorting to cold showers?

Here are 6 tips to help you lower your water heater's energy use! hot_water_heater_controls

Lower the Temperature on Your Hot Water Tank  

By setting your heater's thermostat to 130-140 degrees you can significantly lower your energy usage. Do you know the right temperature for your water heater? If the water heater temperature is set too high, then you can expect to pay an even higher energy bill. If it’s set too low your water might not be hot enough for you and may not be safe. 

Remove Sediment From Your Hot Water Tank

Many homeowners are unaware that sediment buildup in your equipment can reduce the efficiency of the heating elements. Use the valve on the side of your heater to drain the sediment twice yearly.

Insulate Your Hot Water Tank

Install an insulation jacket, and insulate the first six feet of piping that comes off of your heater to prevent heat loss. You can purchase an insulating jacket at most hardware or big box store. 

Install a Water Tank Timer

Most equipment is heating water all day and all night. You can install a heater timer, and set your equipment to run only when you need it. This can save you up to 12% on your heater's energy costs.

Wash Laundry in Cold Water & Wash Full Loads

Using cold water in the washer can add up to big savings. Did you know that 90% of the energy consumed by your washing machine goes to heating water? Turn the dial to cold and wash only full loads to lower your electric bill. 

Install a Tankless Hot Water Heater

The energy savings from tankless hot water heaters or on-demand hot water heaters are tremendous.  These can cut your water heating energy cost by up to 35%. A tankless model can offer an endless supply of hot water, whenever you need it—even for multiple tasks at the same time. No more cold showers or running out of hot water. Your family will love the continual flow of hot water.

Commercial Ventilation Systems

Posted by Ohio Heating

Sep 1, 2021 6:30:00 AM

The circulation of air throughout a building is ventilation. The ventilation of a commercial property relies heavily on the HVAC system. A good HVAC system should provide air to building occupants at a comfortable Ventilation system 2020-1 temperature, at comfortable humidity levels and be free of harmful concentrations of air pollutants.

Improper operation and maintenance of HVAC systems are the most common problems that impact workplace indoor environmental quality (IEQ). 

The heating & air systems serve to dilute and remove contaminants from occupied areas, such as:

  • carbon dioxide and carbon monoxide
  • tobacco smoke
  • molds and bacteria
  • cleaning products
  • copy machines and printers
  • pesticides
  • vehicle exhaust

There are three basic elements to building ventilation:

 1. Ventilation Rate. The amount of outdoor air that is provided into the space, and the quality of the outdoor air 

 2. Airflow Direction. The overall airflow direction in a building, which should be from clean zones to dirty zones

 3. Airflow Pattern. The external air should be delivered to each part of the space efficiently and the airborne pollutants generated in each part of the space should also be removed efficiently.

Mechanical ventilation that is driven by fans and hybrid ventilation systems are the most common types of ventilation in Central Ohio.

With mechanical ventilation, fans can either be installed directly in windows or walls, or installed in air ducts for supplying air into or exhausting air from a room.

The type of mechanical ventilation used depends on the climate. In cold climates, exfiltration needs to be prevented to reduce interstitial condensation, and negative pressure ventilation is used. For a room with locally generated pollutants, such as a bathroom, toilet or kitchen, the negative pressure system is often used. In a negative pressure system, the room is in negative pressure, and the room air is compensated by “sucking” air from outside.

Hybrid ventilation relies on natural driving forces to provide the desired flow rate. It uses mechanical ventilation when the natural ventilation flow rate is too low.

If natural ventilation alone is not suitable, exhaust fans can be installed to increase ventilation rates. This type of hybrid (mixed-mode) ventilation needs to be used with care. The fans should be installed where room air can be exhausted directly to the outdoor environment through either a wall or the roof. The size and number of exhaust fans depend on the targeted ventilation rate and should be measured and tested before use.

The use of exhaust fans can have issues such as difficulty installing large fans, noise especially from high-power fans, increased or decreased temperature in the space and the need for a non-stop electricity supply. If the environment in the space causes thermal discomfort, spot cooling or heating systems and ceiling fans can be added.

Ohio Heating provides a broad range of ventilation and airflow control products for commercial projects. We have systems that can drastically reduce energy consumption and improve the overall indoor air quality of your commercial space. Give us a call at 614-863-6666 to learn more.
