Furnace Installation in New Windsor, NY

Q: How fast can you install a new furnace?

Most furnace installation jobs are completed in a single day. Larger homes or systems needing duct adjustments may take longer, but you’ll always know the timeline beforehand. If you need heat quickly, let us know so we can prioritize your installation.

Q: Do you offer emergency furnace repair if my heat stops suddenly?

Yes, depending on availability, we offer emergency furnace repair for no-heat situations, especially during extreme cold when waiting isn’t safe or practical. If your furnace just stopped and the house is getting cold, call us right away.

Q: What are the signs my furnace needs repair instead of waiting it out?

Cold spots, weak airflow, strange smells, loud noises, rising energy bills, or a furnace that cycles on and off are all warning signs you shouldn’t ignore. These issues usually get worse, not better. If you’re noticing any of these symptoms, book furnace repair before a small issue turns into a full breakdown.

Q: How long does a furnace usually last?

Most furnaces last 15 to 20 years, depending on maintenance, usage, and the fuel type. Older units lose efficiency fast and often cost more to keep running than replacing them. If your furnace is aging and showing signs of decline, we can evaluate it and let you know if replacement is the smarter choice.

Q: Do you work on both home AC repair and commercial AC repair?

Yes. We handle residential and commercial cooling systems, including rooftop units, split systems, and high-demand commercial setups. If your home or building is too warm, we can diagnose the issue and get it cooling properly again.

Stay ahead of the winter cold with a furnace installation built for lasting heat and dependable comfort.

Our Furnace Services

Everything your home needs to stay heated, safe, and fully functional through the toughest winter conditions

From sudden breakdowns in the middle of winter to complete furnace upgrades, we take care of everything your home needs to stay comfortable and protected through winter.

Furnace Installation
and Replacement

Is your furnace struggling to heat the house, running louder than usual, or taking too long to warm the rooms you use every day? That often means the system is too old or too small for the home. Book our furnace installation service so we can set up the right-sized unit and restore steady, reliable heat before winter cold becomes a daily battle.

Furnace
Repair

Are you dealing with cold spots, a furnace that keeps shutting off, or heat that disappears as soon as it turns on? These issues rarely fix themselves and usually get worse the longer you wait. Schedule our furnace repair service so we can track down the real problem and get your home warm again before the system fails completely.

Gas Furnace
Repair

Is your gas furnace blowing cool air, struggling to ignite, or making clicking or popping sounds? Those symptoms point to a failing component that could shut the heat off entirely. Book our gas furnace repair so we can diagnose the cause and restore safe, consistent heating before it leaves your home cold.

Gas Furnace
Replacement

If your gas furnace is older, losing efficiency, or needing repair after repair, it may be past its lifespan. Older units often burn more fuel than they should and still can’t heat the home properly. Schedule our gas furnace replacement so we can install a modern, efficient system that keeps your home warm without constant issues.

Oil Furnace
Replacement

Is your oil furnace leaking, running dirty, or costing more and more to maintain every year? Why keep fueling a system that is past its lifespan? Book our oil furnace replacement, and we’ll install a cleaner, more efficient unit that heats your home without constant problems.

Furnace
Maintenance

Is your furnace noisy, slow to heat, or giving signs that it might fail when the weather gets colder? Why wait for a full breakdown in the middle of winter? Book our furnace maintenance so your system stays clean, efficient, and ready to run when you need it most.

Furnace Installers

Trusted in New Windsor

Furnace installation can fix uneven heating, cold rooms, and rising energy bills, but only when it’s installed correctly. A furnace that is sized wrong, vented poorly, or rushed through installation can create expensive problems such as poor airflow, short cycling, early failure, and rooms that never feel warm. Homeowners end up paying for more repairs, more fuel, and more frustration because the system was never set up the way it should have been.

With three generations in the trade, dependable customer service, and a satisfaction guarantee, you get a heating setup that actually solves your comfort issues instead of creating new ones.

The furnace is constantly turning on and off
Heating bills that rise quickly
Burner smell or unusual odors

Your Furnace Questions

Answered Clearly and Without Confusion

How do I know if I need furnace repair or a full furnace replacement?

If your furnace is older than 15–20 years, breaking down often, heating unevenly, or causing bills to rise fast, replacement is usually the better choice. If the issue is smaller, like a failing ignitor, a thermostat problem, or a clogged filter, furnace repair is enough.

If you’re not sure which one you need, we can inspect the system and tell you exactly what makes sense for your home and budget.

CJM had to come twice this week. The first time to service our oil burner and the second time, Makaya, came to repair our leaky kitchen sink. Both times the servicemen did a great job - friendly, competent and expedient. I didn't catch the name of the first service person, but Makaya did a great job with our sink. Quick and pleasant --- even whistled while he worked. Literally. LOL. The woman who handles the phone is a great rep, too. Great doing business with this organization.
