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 probable issues, your home comfort system should receive the same kind of attention. Routine maintenance by a professional 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 operate 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 run longer and more efficiently. Two-stage heating also runs more quietly than traditional furnaces and can give you 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 works 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 designed to offer 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 designed to operate with other high-efficiency HVAC products, such as air conditioners. The air conditioner blowers give your heating system an extra bump so it can deliver cool air around your home efficiently. Special features like variable speed motors will also help reduce 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 increased the minimum efficiency levels for air conditioners, heat pumps and packaged units manufactured after Jan. 1, 2015, since heating and cooling contributes significantly to a home’s total energy usage. The requirements vary by region, so call Daniel's Heating & Refrigeration Corp. for the efficiency standards for Midlothian.

How can I reduce my energy costs?

Heating and cooling makes up a large portion of your monthly utility bill. Purchasing 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 lowering energy output. Beyond these ratings, also consider:

  • Routine maintenance – regularly having an expert tune-up your equipment will keep it working 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 routinely used.
  • Installing a programmable thermostat – the Department of Energy estimates that a programmable thermostat can reduce 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.

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 full of with air pollutants floating around your home, so to improve IAQ, the first step is to get rid of as many pollutants as possible. You can easily do this is by cleaning and vacuuming at least once a week, frequently 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 exchange 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 picking up microscopic particles, killing germs and removing particles and germs while destroying chemical vapors.
  • Monitor – programmable thermostats will help you monitor 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 might be surprised to know that air conditioners don’t technically make your home cooler; they actually remove the hot air and transfer it outside. This hot air is pushed across a refrigerant coil on the indoor unit and then is sent to the outdoor unit where it is released. Your air conditioner transfers 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?

Different regions have different minimum energy efficiency standards. Additionally, air conditioners, heat pumps and packaged units made after Jan. 1, 2015, have higher minimum efficiency levels than equipment manufactured prior to that date. The team at Daniel's Heating & Refrigeration Corp. can help you find out the minimum requirements for Midlothian, 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 find out the correct size equipment for your home is to have a technician from Daniel's Heating & Refrigeration Corp. 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 an air conditioner uses two-stage cooling, it means that there are two levels of operation. This lets the system work most effectively since there is one level for milder weather and a second 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 number 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 fix as a homeowner, but the others need to be completed by a professional like those at Daniel's Heating & Refrigeration Corp.. Contact them at 804-379-1155 with any other questions.

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

Daniel's Heating & Refrigeration Corp. offers a number of great thermostat options for your HVAC systems. The best thermostat for you will depend on a variety of 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 Daniel's Heating & Refrigeration Corp. to hear about which thermostats you can choose from. Our team will help you find one that’s right for your system, your family’s needs and your budget.

What is a heat pump?

A heat pump can tackle both your home’s heating and cooling needs, offering you one HVAC system that can be used year-round. In the warmer months, heat pumps act like an air conditioner, capturing the hot air from inside your home and moving 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 Daniel's Heating & Refrigeration Corp., we do recommend replacing both your indoor and outdoor units at the same time because:

  • Outdoor systems are now built to work with their matching indoor system for maximum efficiency. When you replace just one of your systems, you may not see the same energy savings as if you had replaced them together.
  • Thanks to technological advancements, newer systems mean increased efficiency. This is also true for HVAC systems. While the advancements focus on higher heating and cooling efficiency, they also include benefits such as better air handling, filtering and noise reduction.
  • If your heating and cooling systems are more than 10 years old, they need to be replaced. Older models have outdated technology that is likely contributing to higher energy bills 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.
