When it's time to upgrade your furnace, rely on Comfort Air, Inc. Mechanical and Plumbing Contractors for expert sizing and premium, energy-efficient heating solutions for your home.

Replace Your Furnace

Home and business owners in Stockton depend on their heating systems during the brief cooler months of the year. A furnace failure in winter can leave you feeling cold and uneasy. However, discomfort isn't the sole reason to seek emergency furnace service. A faulty heater has the potential to ignite a fire or emit hazardous gases, such as carbon monoxide. Additionally, your aging furnace might be consuming more energy and incurring higher costs than necessary.

When the only feasible option is to replace your furnace, don't take any chances. The professionals at Comfort Air, Inc., Mechanical and Plumbing Contractors are well-versed in the most advanced models and the latest technologies. As an esteemed Carrier dealer, we provide exceptional installation and Carrier furnace service, all supported by a 100% satisfaction guarantee. You'll enjoy consistent warmth and energy savings that an outdated furnace simply cannot provide.


For individual equipment replacements, our furnaces are backed by a 5-year parts and 2-year labor warranty. If you choose a complete HVAC system replacement, you'll receive even greater coverage with a 10-year parts and 2-year labor warranty.

When to Replace Your Heater

Regular maintenance and repair of your furnace can significantly prolong its lifespan. However, there will inevitably be a point when the most sensible choice is to purchase a new unit. This decision is rarely straightforward and often arises when least anticipated.

  • Your Furnace Is Aging: Generally, a gas furnace has a lifespan of about 15 to 20 years, whereas an electric furnace can endure for up to 30 years. If your older furnace is underperforming or losing efficiency, our technicians will usually advise you to consider a replacement.
  • Unusual Noises: A popping sound from your furnace, coupled with fluctuating temperatures, may indicate that internal components are affected, while a rattling noise can suggest something is loose within the unit. A screeching noise often points to problems with a belt, pulley, or blower motor. Booming noises may signal gas emission issues, and a progressively louder humming sound could mean your furnace is approaching the end of its useful life.
  • Inconsistent Temperatures: Ideally, the temperature should be fairly uniform throughout your home. If you experience noticeable variations as you move from room to room, it’s a sign that your furnace may struggle to evenly distribute heat.
  • Dirty Furnace Register: If you see soot around the furnace register and grille, your home feels dustier, and the air seems dry, it may indicate that your unit is generating excessive carbon dioxide. Additional signs include damage to wooden floors and furnishings due to dry air, along with wilting houseplants. In such cases, replacing your furnace may be the most effective solution.
  • Flame Color Issues: The flame produced by a furnace should consistently be blue. Yellow flames raise serious concerns, as they may indicate a gas leak, combustion issue, or the presence of carbon monoxide. If the underlying problem cannot be addressed, we will recommend replacing your furnace with a new, energy-efficient model.
  • Rising Operating Costs: Keep a vigilant eye on your expenses. As an aging furnace operates harder, it consumes more energy, leading to increased utility bills. Repair costs should also be considered—if the cost of repairs exceeds half the price of a new furnace installation, it may be time to look into a replacement.

Professional Sizing & Installation

At Comfort Air, Inc., Mechanical and Plumbing Contractors, our team conducts a comprehensive assessment of your home prior to the installation of a new heater. We take into account various factors such as the size of your home, the number of residents, the local climate, and many other considerations. Our objective is to install a furnace that is perfectly sized for your needs. An oversized or undersized unit can lead to increased energy consumption, premature wear, and the likelihood of needing repairs and replacements sooner than expected. We ensure this doesn't occur, allowing you to save money throughout the lifespan of your furnace, beginning with an accurate estimate that we adhere to during the entire process.


During the installation phase, we commit to upholding the highest standards. From the initial setup to the essential connections, as well as the upgrades to ducts, ventilation systems, exhaust components, and electrical circuits, our team is devoted to ensuring your new heater operates reliably and safely for years to come. Additionally, we take steps to protect your home by using floor mats and protective shoe covers, responsibly disposing of the old unit, and providing a thorough explanation of how the new system operates.

HEAR FROM SATISFIED CLIENTS


I will definitely use them again. The technician showed me the problem- repaired it. He went out of his way to do several minor things that he did not have to do as was being helpful to me. My father is a general contractor but being 83 years old and lives in another city he doesn't get around as well anymore but he tells me what to look for when somebody comes to do a repair. I can't count how many times i have been taken advantage of in the past. Comfort Air was awesome and very reasonably priced. Very honest and that is so refreshing.

Only good experiences with this outfit. Our old AC broke down about six years ago, and two other companies couldn't identify the problem and submitted much higher bids to replace. Comfort Air was quick, reasonably priced, and efficient, and the unit works great. They didn't try to sell us an entire new HVAC system like other outfits did. Only one minor repair after six years, and that was handled quickly, responsibly, and efficiently. When we need to replace our now 40-year-old furnace, we'll definitely call this company.

They did a great job of replacing my old gas furnace/AC unit with a heat pump replacement. Job was done quickly and efficiently with a great price. Have already referred them to potential customers and will continue to do so. A very professional and competent group of workers!

Keira S.

★★★★★

Came out, figured out the problem with my furnace immediately and fixed it. Super honest and trust worthy. Replace the my circuit board and I have heat again ($400 job). Had another company come out before them and told me I needed a new full HVAC system that would cost me $25K.
