We understand. Furnaces are more efficient than ever, with a plethora of features designed to keep you comfortable. They come in different sizes and shapes, some more powerful than others. They also have different price points based on their efficiency ratings.
The thermostat is the brains of your heating, ventilation, and air conditioning (HVAC) system. But it’s the furnace that provides all the muscle, teaming up with your ductwork to send warm air throughout your New Jersey, home.
And always remember, a happy home is a warm one! It would only take a few cold days in a row with no indoor heat for all the pipes in your home to freeze.
What matters most is to pick the right furnace that fits your budget and the size of your home. Our team at Delco Air has the knowledge and expertise to help you make that choice. We’re a trusted name in the Old Bridge, NJ, area for creating healthy homes. Give us a call today—we can schedule a free consultation to help with your next home improvement project.
Choosing the Right Furnace by Fuel Type
Your first decision is easy: choosing the fuel type.
The most common source is natural gas. Your local utility company supplies the fuel delivered to your home through an underground gas line. The price of natural gas is relatively stable, so you don’t have to worry about cost fluctuations. Plus, you never need to worry about storage.
Gas furnace
If you have access to a natural gas line, we strongly recommend a gas furnace. These furnaces have proven their value over the years for providing steady comfort on the coldest of days.
Oil furnaces
Oil furnaces are a popular alternative in the United States, particularly in parts of the Northeast that do not have easy access to natural gas. These types of furnaces last longer than a gas furnace but do not operate as efficiently. Oil prices fluctuate more than natural gas prices, making it harder to gauge your monthly expenses. Plus, you will need a storage tank for the oil.
Electric furnaces
Electric furnaces tend to last longer than gas furnaces and cost less to install. On the other hand, they are more expensive to operate and take longer to heat your home. Anyone living in a cold climate would enjoy more comfort with a gas or oil furnace.
Choosing the Right Furnace Speed
Furnaces run at different speeds. The operating speed you choose will impact your comfort, budget, and indoor air quality (IAQ).
Single-stage furnaces
Single-stage furnaces have just two settings, on or off. Your furnace switches on and continues to run to reach the desired temperature. Once it reaches the temperature, the furnace turns off. Single-stage furnaces are the most affordable models and easiest to install. But they are the least efficient and tend to create hot and cold spots in larger homes.
Two-stage furnaces
Two-stage furnaces run at full-speed and half-speed. This allows your furnace to heat your home more evenly, producing a more consistent temperature from room to room.
In addition to producing better heating, the half-speed setting is much quieter.
Variable speed furnaces
Variable speed furnaces are the gold standard of the heating world. These models adjust their speeds to provide precise comfort. They run longer at slower speeds, improving efficiencies while lowering your energy bills. Because they do not frequently cycle on and off, these systems tend to have fewer breakdowns.
Variable speed furnaces are much more adept in maintaining your indoor air quality, catching harmful particles, and eliminating excess moisture that causes mold growth. Larger homes benefit tremendously from variable speed furnaces.

Choosing an Efficient Furnace
The AFUE (annual fuel utilization efficiency) rating on your furnace indicates how much energy it converts. An energy-efficient furnace with an AFUE rating of 95 can convert 95 percent of the energy it consumes into heat.
The higher the AFUE rating, the more money you save on monthly utility bills. Energy-efficient furnaces emit fewer greenhouse gases and make less noise when they operate. If you want to reduce your home’s carbon footprint, the perfect place to start is with your heating and cooling equipment!
Furnace Installation or Replacement
Don’t invest in a quality HVAC system and then hire a substandard contractor to install it. You will never enjoy the full benefits of a system installed incorrectly.
At Delco Air, we specialize in installing equipment the right way. We take our time to ensure everything is measured correctly. Our team will also conduct a thorough energy audit of your home to find additional ways to lower your energy use.
Be sure to ask about our convenient financing options designed to make it easy for you to create your dream home.

EXCELLENT Based on 102 reviews Scott Forgue2025-01-24Trustindex verifies that the original source of the review is Google. We called Delco Air due to the heat not working in our student housing property on one if the coldest days. They sent a tech over within a short time and resolved the problem to get the heat working. The tech also provided a small list of items that need to be addressed to prevent future problems. The cost was more than reasonable and we recommend anyone to use them.

Karina Z2025-01-12Trustindex verifies that the original source of the review is Google. I recently had the pleasure of working with Delco Air to replace my aging furnace, and I couldn’t be more impressed with their service from start to finish. From the moment I reached out for a quote, their customer service was top-notch. The team at Delco Air was friendly, professional, and thorough in explaining the options available for a new furnace. They took the time to assess my home’s heating needs and helped me select the perfect system for both efficiency and comfort. I appreciated their transparent pricing and no-pressure approach. I was fortunate to have Ryan doing the work and he was knowledgeable, professional & efficient. The installation was seamless. The technicians arrived right on time, and they were incredibly courteous throughout the entire process. They protected my floors and furniture, removed the old furnace, and installed the new system without any issues. They even took the time to walk me through the new unit, explaining how to use it and offering maintenance tips to keep it running efficiently. Since the installation, my home has been warmer, more comfortable, and more energy-efficient. The new furnace heats the house evenly, and I’ve already noticed a decrease in my heating bills. It’s also much quieter than my old system, which was a pleasant surprise. I can’t recommend Delco Air enough! Their professionalism, expertise, and commitment to customer satisfaction are truly exceptional. If you’re considering furnace replacement, don’t hesitate to give them a call—you won’t be disappointed! Nestor Negroni2025-01-11Trustindex verifies that the original source of the review is Google.

The company I used in the past were not able to service my furnace because they did not have any parts in stock and they are a carrier repair service. I called Delco and spoke to the service manager Mark and they were able to locate the part in minutes. They sent their service tech out, Ryan and he had heat back on within 30 minutes. Thanks to the Delco team for a quick response and excellent service. I know who I will call going forward.

Delco Air are the best hvac and plumbers in New Jersey my hot water tank cracked last night and flooded my basement I called delco air because they fixed my air conditioning over the summer. The technician got here at 5pm and explained to me how although the crack is an area of in-repair he can schedule replacement Monday or check to see if they had my style hot water heater in their inventory and offered to replace it on the spot the same day and I was shocked that they would offer that level of service and I accepted and he had the replacement done by 10pm and was cleaned up and had the old hot water tank out of my home by 1030 and me and my wife would recommend them to anyone literwally
