Modern furnaces are developed with a variety of innovative features older furnaces don't have. Todays heating systems offer more even heating and are better at controlling airflow. Although the air coming out of your vents may seem cooler than your old furnace, the airflow is much better and more efficient.

Another perk of modern furnaces is their ability to integrate with other HVAC products as part of a high-efficiency whole home comfort system. When combined with a high-efficiency air conditioner, furnace blowers can more easily accommodate add-on cooling. Other innovations, such as Precise Comfort technology and variable speed motors, will help your furnace work more efficiently and quieter than ever.

The Department of Energy recently increased the minimum efficiency levels for air conditions, and the standards vary by region. Contact Kowalski Heating, Cooling & Plumbing at 724-370-0141 to find the requirements for the McMurray area.

Kowalski Heating, Cooling & Plumbing carries a number of HVAC products with high-efficiency ratings, which can help reduce the amount of energy they require to operate.

  • Making certain that your system receives routine maintenance by a trained expert can keep your system operating at its top performance.
  • Zoning systems enable you to heat or cool only targeted areas of your home, so you wont have to pay to heat or cool spaces that aren't used.
  • Using 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 need when you're home and increase or decrease the temperature while you're not around, helping you save on heating and cooling costs.

Improving your homes indoor air quality starts with four basic strategies:

  • Poor indoor air quality leaves your home filled with air pollutants floating around. So, to improve 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 weekly, frequently washing linens and storing cleaning products safely.
  • Proper insulation is good 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 have 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 removing particles while destroying chemical vapors.
  • Programmable thermostats will help control the humidity levels and temperature to help avoid particles and germs from building up while also keeping your home comfortable.
We advise that you meet with one of the professionals at Kowalski Heating, Cooling & Plumbing and have them perform an evaluation of your home and current indoor comfort system. We can help you choose which equipment will be best suited to meet your needs.
Most homeowners believe that air conditioners make the air in your home cooler, but it actually removes the heat from inside your home, directing the hot air outside. That hot air flows across a cold indoor coil where refrigerant in the lines sends the heat to the coil in your outdoor unit, releasing the hot air outside. This cycle continues until the indoor temperature reaches the desired level that you 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. Kowalski Heating, Cooling & Plumbing can help answer any questions you may have regarding these minimum requirements and let you know what choices are available when you're in the market for a replacement system.
These numbers are located on a nameplate or sticker that is near your systems service panel. The sticker should be white with black letters and have both of these numbers located at the top of the sticker. M/N denotes model number while S/N is your serial number.
There are a handful of ways to determine what size system is right for your home, but the most reliable way to determine the right size system is by having your local Kowalski Heating, Cooling & Plumbing technician come out and perform a load calculation. This calculation considers your homes: square footage, insulation value, amount of insulation, and a handful of other factors.
Yes, because dirt and other debris can impede your systems 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 types of conditions.
Two-stage cooling means that your cooling unit has two levels of operation. When summer is its warmest, the high setting starts up, and when its cooler or more mild, the low setting handles the duties. Most of the time, the lower setting will take care of your cooling needs, but even when the high setting kicks in, you may not realize it because it can generate such even temperatures for your comfort. This may also mean a quieter cooling system, greater efficiency and improved humidity control.
Your system could be freezing up for a number of reasons, but the most common are dirty filters, low refrigerant, a dirty evaporator coil and/or a faulty blower motor. Changing a filter is something homeowners take care of; however, you'll want to call the professionals at Kowalski Heating, Cooling & Plumbing at 724-370-0141 for other problems or if you have other questions or concerns.
Choosing the best thermostat for your cooling system comes with a lot to think through. Thats why its nice to have such a big variety of choices from Kowalski Heating, Cooling & Plumbing. Whether you're looking for a programmable or non-programmable thermostat or want to join the smart home trend, there are various thermostats that you have to pick from. Some thermostats will depend on what type of heating and cooling system you have, but the pros at Kowalski Heating, Cooling & Plumbing will be able to help determine what options fit your needs and your budget.
Heat pumps can be a little confusing due to their name, but they actually take care of both your heating and cooling needs year-round. When its hot outside it runs like an air conditioner in that it removes heat from your home, but when it cools off, the process gets switched around and it collects heat from outside and brings it inside. Heat pumps are also very efficient, and could 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 designed to work with to ensure efficient performance. When they aren't paired with the other part as a total system, efficiency might suffer.
  • As with most products, advancements have brought about newer, more efficient ways of doing things. Heating and cooling systems are no different. These improvements most importantly include greater heating and cooling efficiency, but also include improved air handling, filtering and noise pollution reduction to name a few.
  • Heating and cooling systems that are more than 10-15 years old normally need to be replaced. Not only do they feature outdated technology, but they are also less efficient than todays models. Getting a new indoor unit at the same time means you'll have a matched system to provide you with better 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 should visit this website to learn more about the system's status, energy production and environmental benefits. The site also shows carbon offsets as it happens.
In most locations, rain will be enough to keep the solar modules clean. If you live in a dusty or industrial area, periodically spraying the modules with water can help improve performance. However, detergents and high-pressure hoses should never be used to rinse solar modules.
The proper thermostat for you depends on your heating and cooling equipment. Kowalski Heating, Cooling & Plumbing has programmable and nonprogrammable thermostats that can help increase the efficiency of your HVAC systems. Browse our available products or contact us at 724-370-0141 to learn more.

Heating and cooling can make up a significant amount of your utility bill. The innovative and high-efficiency heating and air conditioning products available from Kowalski Heating, Cooling & Plumbing can help decrease these costs. If you're looking 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 higher the number, the more efficient the product. Besides purchasing a new home comfort system, consider these additional factors:

  1. Is your system consistently maintained? Whether it's a furnace or air conditioner, HVAC systems will work more efficiently after regular maintenance checks.
  2. Would you benefit from a zoning system? If there are spaces 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.
  3. Are you taking advantage of 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 equipment gives you the ability to section off areas of your residence and control the temperature differently in each part of your home. These systems are best for when you have areas of your home that are seldom used or when you and your family are always in disagreement of how hot or cold it ought to be inside. Zoning systems are almost noiseless and efficient, enabling you to have more control over the comfort of your family home.
