Why does my home comfort system need regular maintenance?

Just like you need to take your car in to the shop for regular tune-ups, such as oil changes or inspecting potential concerns, your home comfort system should receive the same kind of attention. Regular maintenance by a trained technician provides various benefits to your HVAC equipment, which can help your systems operate efficiently and prevent costly breakdowns.

What is two-stage heating?

With two-stage heating, furnaces may work on two different levels: high and low. Since you can heat your home on the low setting a lot of the time, a two-stage furnace can operate longer and more efficiently. Two-stage heating also operates more quietly than traditional furnaces and can provide more even heat distribution and fewer temperature swings.

What is Precise Comfort™ technology?

Lennox’s Precise Comfort™ technology is an operating and control system that permits a furnace to adjust heat and airflow by very small amounts, as low as a 1 percent change. The system is automatic and runs similar to cruise control, making adjustments gradually to meet your comfort demands with energy efficiency.

Will my new furnace work differently than my old one?

Depending on how old your previous furnace was, you could experience a number of differences. Furnaces today are created to provide more even and efficient heating than ever before. Modern furnaces also better regulate temperature and air flow, moving more air over the heat exchanger than older furnaces.

Additionally, new furnaces are created to operate with other high-efficiency HVAC products, such as air conditioners. The air conditioner blowers offer your heating system an extra boost so it can deliver cool air around your home efficiently. Special features like variable speed motors will also help decrease noise associated with operating your equipment and easily meet your family’s airflow needs.

What is the energy efficiency standard for air conditioners?

The Department of Energy recently raised the minimum efficiency levels for air conditioners, heat pumps and packaged units created after Jan. 1, 2015, since heating and cooling contributes significantly to a home’s total energy usage. The requirements vary by region, so call Temptrol Heating & Cooling Inc. for the efficiency standards for Antioch.

How can I reduce my energy costs?

Heating and cooling makes up a significant portion of your monthly utility bill. Buying HVAC equipment with high efficiency ratings, such as SEER for air conditioners and AFUE for furnaces, is a simple step that can go a long way in reducing energy output. Beyond these ratings, also ponder:

  • Routine maintenance – regularly having an expert tune-up your equipment will keep it operating at its highest potential.
  • Adding a zoning system – by focusing your heating and cooling on the rooms you use most frequently, you won’t have to pay to heat or cool areas of your home that aren’t used often.
  • Installing a programmable thermostat – the Department of Energy estimates that a programmable thermostat can decrease heating costs by up to 35 percent and cooling costs by up to 25 percent. Leave it up to your thermostat to turn down the heat when you’re away and go back to your preferred temperature when you’re home.

Why should I buy a Lennox product?

How can I improve my home’s indoor air quality?

Boosting your home’s indoor air quality starts with four basic strategies:

  • Eliminate – poor indoor air quality leaves your home filled with air pollutants floating around your home, so to improve IAQ, the first step is to eliminate as many pollutants as possible. You can easily do this is by cleaning and vacuuming at least once a week, routinely washing linens and storing cleaning products safely.
  • Ventilate – proper insulation is great for keeping your home warm in the winter and cool in the summer, but it also makes it harder for airborne pollutants to escape. Products like our Healthy Climate® ventilation system help swap stale air for fresh, filtered outside air.
  • Clean – good ventilation and regular cleaning are a start, but Healthy Climate® air filters, germicidal lights and PureAire™ purification systems take your IAQ to the next level by holding microscopic particles, killing germs and removing particles and germs while destroying chemical vapors.
  • Monitor – programmable thermostats will help you control the humidity levels and temperature to help prevent particles and germs from accumulating and keep your home comfortable.

How does an air conditioner work?

You may be surprised to learn that air conditioners don’t technically make your home cooler; they actually remove the hot air and transfer it outside. This hot air moves across a refrigerant coil on the indoor unit and then is sent to the outdoor unit where it is released. Your air conditioner pushes as much hot air outside as is necessary to reach the temperature you have set on your thermostat.

What is the minimum energy efficiency standard for air conditioners in my state?

Minimum energy efficiency standards can vary by geographic location. Additionally, air conditioners, heat pumps and packaged units made after Jan. 1, 2015, have higher minimum efficiency levels than HVAC products manufactured prior to that date. The team at Temptrol Heating & Cooling Inc. can help you find out the minimum requirements for Antioch, let you know if your current products meets those requirements or help you find a replacement air conditioner that does.

What size equipment do I need for my home?

Since equipment size needs vary by home, the best way to determine the right size equipment for your home is to have a technician from Temptrol Heating & Cooling Inc. come out to perform load calculation tests. The tests take things like square footage, insulation value and amount, and more into account to determine your home’s individual HVAC equipment needs.

What is two-stage cooling?

When a cooling system uses two-stage cooling, it means that there are two levels of operation. This allows the system to work as efficiently as possible since there is one level for milder weather and one for harsher weather that demands the system work harder. Two-stage cooling also enables slight temperature changes so you don’t experience extreme differences in temperature. Aside from better efficiency, other benefits of two-stage cooling include quieter operation and enhanced humidity control.

Why is my cooling unit freezing up?

When your cooling unit freezes up, there are a couple of reasons why it could be doing so. The most typical reasons include: dirty filters, low refrigerant, a dirty evaporative coil and a faulty blower motor or relay. A dirty filter is something you can change as a homeowner, but the others need to be completed by a professional like those at Temptrol Heating & Cooling Inc.. Contact them at 847-838-2156 with any additional questions.

What is the best thermostat to use for my cooling system?

Temptrol Heating & Cooling Inc. carries a number of great thermostat options for your HVAC systems. The best thermostat for you will depend on a couple variables, such as whether you want one that’s programmable or not. No matter what kind of thermostat you’d like – or if you’re in the market for something that can fit with a home automation system – call Temptrol Heating & Cooling Inc. to hear about which thermostats you can choose from. Our team will help you find one that fits with your system, your family’s needs and your budget.

What is a heat pump?

A heat pump covers both your home’s heating and cooling needs, offering you one HVAC system that can be used all year. During the warmer months, heat pumps act like an air conditioner, capturing the hot air from inside your home and directing it outside; in the cooler months, this process is reversed. Heat pumps can be very energy efficient and may produce two to three times more heat than the energy used.

When replacing the outdoor unit, should the indoor unit also be replaced?

At Temptrol Heating & Cooling Inc., we do recommend replacing both your indoor and outdoor units at the same time because:

  • Today, outdoor systems are built to work with their matching indoor system for maximum efficiency. When you replace only one of your systems, you may not see the same energy efficiency levels as if you had replaced them together.
  • Thanks to technological advancements, newer systems mean increased efficiency. This is true for HVAC products as well. While the advancements focus on greater heating and cooling efficiency, they also include benefits such as better air handling, filtering and noise reduction.
  • If your heating and cooling systems are 10+ years old, they need to be replaced. Older models have outdated technology that is likely costing you money due to poor efficiency. So by replacing your indoor system at the same time as your outdoor equipment, both your systems will provide better energy efficiency that helps you lower your energy bills and keep your home more comfortable.
