Two-stage heating enables the furnace to heat at two levels of output: high for cold winter days and low for mild ones. Around 80 percent of the time, your home’s heating requirements can be met when the furnace is set on the low setting, permitting your two-stage unit to run for longer periods of time. Two-stage units also offer more even heat distribution, fewer temperature swings, quiet operation, increased air filtration and energy efficiency.

Bell Mechanical Services has an assortment of brands and models that are more efficient than ever and make it easier to find the right fit for your home. There are innovative systems that make heating or cooling your home more automatic, operating similar to cruise control to make small adjustments to help meet your comfort demands with energy efficiency.

Depending on how old your previous furnace was, you could experience a host of differences. Furnaces today are created to give 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 crafted to integrate with other high-efficiency HVAC products, such as air conditioners. The air conditioner blowers offer your heating system an extra lift 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.

The Department of Energy recently increased 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 Bell Mechanical Services for the efficiency standards for McKinney and Frisco.

Bell Mechanical Services offers a number of HVAC products with high-efficiency ratings, which can help reduce the amount of energy they require to operate. Aside from picking products that have received Energy Star® certification or achieved high SEER ratings for air conditioners or AFUE ratings for furnaces, you can consider the following:

• Making certain that your system receives regular maintenance by a trained technician can keep your system operating at its top performance.
• Zoning systems enable you to heat or cool only specific areas of your home, so you won’t have to pay to heat or cool spaces that you aren’t using.
• Having a programmable thermostat allows you to set the temperature in your home around your schedule. They can be programmed to give you the comfort you desire when you’re home and increase or decrease the temperature while you’re not around, helping you save on utility costs.

Bell Mechanical Services is well-known in the McKinney and Frisco area and you can rely on them to provide quality home comfort products. We feature a variety of innovative and high-quality products. We are dedicated to providing customers high-quality service and will make sure you find the right solution for your home.

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

• Poor indoor air quality leaves your home full of air pollutants floating around. So, to enhance IAQ, the first step is to get rid of as many pollutants as possible. You can easily do this by cleaning and vacuuming at least one time during the week, frequently washing linens and storing cleaning products safely.
• Proper insulation is ideal for keeping your home warm in the winter and cool in the summer, but it also makes it difficult for airborne pollutants to escape. We offer products that help swap stale air for fresh, filtered outside air.
• Good ventilation and routine cleaning are a start, but air filters, germicidal lights and purification systems take your IAQ to the next level by capturing microscopic particles, killing germs and eliminating particles while destroying chemical vapors.
• Programmable thermostats will help control the humidity levels and temperature to help stop particles and germs from building up while also keeping your home comfortable.

We recommend that you meet with one of the professionals at Bell Mechanical Services and have them assess your home and current indoor comfort system. We can help you choose which equipment will be best suited to meet your needs.

Lots of homeowners believe that air conditioners make your home cooler, but it actually removes the heat from inside your home, directing the hot air outside. That hot air goes across a cold indoor coil where refrigerant in the lines sends the heat to the coil in your outdoor unit, releasing it outside. This cycle continues until the indoor temperature reaches the temp that was set on your thermostat.

Due to the amount of energy used by heating and cooling systems, the Department of Energy (DOE) increased the minimum efficiency levels for air conditioners, heat pumps and packaged units manufactured after January 1, 2015. These levels are determined by region and carry varying requirements based on your location. Bell Mechanical Services can help answer any questions you may have regarding these minimum requirements and let you know what choices are available when you’re looking for a replacement system.

These numbers can be found on a nameplate or sticker that is near your system’s service panel. The sticker is white with black letters and has both of these numbers located near the top of the sticker. M/N signifies model number while S/N is your serial number.

There are a couple ways to determine what size system is the best fit for your home, but the most reliable way to size a system is by having your local Bell Mechanical Services technician come out and perform a load calculation. This calculation considers your home’s square footage, insulation value, amount of insulation, and a number of other factors.

The short answer is yes. Dirt and other debris can impede your system’s ability to work efficiently. For heat pumps, it is not unusual to have frost or ice on them during the winter, but they also feature defrost controls to ensure they work efficiently in those kinds of weather.

Two-stage cooling means that your cooling unit has two levels of operation. When summer is in its hottest weeks, the high setting is used, and when it’s cooler or more mild, it operates on the low setting. Typically, the lower setting is able to take care of your cooling needs, but even when the high setting kicks in, you may not realize it because it can produce such even temperatures for your comfort. This can also mean a quieter cooling system, greater efficiency and improved humidity control.

When your cooling unit freezes up, there are a variety of reasons why it could be doing so. The most common 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 done by a professional like those at Bell Mechanical Services. Contact them at 888-863-0560 with any additional questions.

Choosing the best thermostat for your cooling system comes with a lot of considerations. That’s why it’s nice to have such a big variety of choices from Bell Mechanical Services. Whether you’re looking for a programmable or non-programmable thermostat or want to join the smart home trend, there are a number of thermostats that you have to select from. Some thermostats will depend on what type of heating and cooling system you have, but the pros at Bell Mechanical Services will be able to help determine what options meet your needs and your budget.

Heat pumps can be a little confusing due to their name, but they actually cover both your heating and cooling needs all year. When it’s hot outside it operates like an air conditioner in that it removes heat from your home, but when it cools off, the process gets turned around and it collects heat from outside and brings it inside. Heat pumps are also very efficient, and might produce up to two or three times more heat than the energy it uses.

Of course we suggest you also replace your indoor system, but this is why:

All outdoor cooling systems have a matching indoor unit that they are intended to work with to ensure efficient performance. When they aren’t paired with the other piece as a total system, efficiency can be affected. As with many products, advancements have brought about newer, more efficient ways of doing things. Heating and cooling systems are no different. These improvements most importantly include better heating and cooling efficiency, but also involve improved air handling, filtering and noise pollution reduction to name a few.

Heating and cooling systems that are more than 10–15 years old usually need to be replaced. Not only do they consist of outdated technology, but they are also less efficient than more recent models. Getting a new indoor unit at the same time means you’ll have a matched system to provide you with even more comfort and efficiency for years to come.

The communication module on your home energy system may send the system’s performance records for each module to a website. You may visit this website to learn more about the system’s status, energy production and environmental benefits. The site also shares carbon offsets as it happens.

In most areas, rain will naturally clean the solar modules. If you are located in a dusty or industrial area, periodically spraying the modules with water could help improve performance. However, detergents and high-pressure hoses should never be used to clean solar modules.

Heating and cooling can make up a large part of your utility bill. The innovative and high-efficiency heating and air conditioning products available from Bell Mechanical Services can help lower these costs. If you’re shopping for a new heating or cooling system, look for products with high SEER ratings for air conditioners and AFUE ratings for furnaces. SEER and AFUE are a measure of system efficiency, and the larger the number, the more efficient the product. Besides purchasing a new home comfort system, consider these additional factors:

• Is your system regularly maintained? Whether it’s a furnace or air conditioner, HVAC systems will run more efficiently after regular maintenance checks.
• Could your home use a zoning system? If there are rooms in your home that are rarely used, a zoning system will allow you to heat or cool only the most used areas of your house.
• Does your home have a programmable or smart thermostat? According to the U.S. Department of Energy, programmable thermostats may lower your heating costs by up to 35 percent, and your cooling costs by up to 25 percent.

Zoning your home allows you the comfort of sectioning portions of your house and controlling the thermostat differently in each area. Zoning equipment is best for when you have parts of your home that are seldom used or when you and your family are often in disagreement of what the temperature in each area of your home should be. Zoning systems are quiet and efficient, giving you more control over the comfort of your house. Discover more about the equipment available from Bell Mechanical Services.
