Our Approach to Furnace Repair & Installation
A reliable furnace matters when temperatures drop. J&R Mechanical Services provides furnace diagnostics, maintenance, repairs, and complete installations — ensuring your home stays warm and your system runs safely and efficiently.
Whether your furnace is making strange noises, not heating evenly, or has stopped working entirely, our technicians can diagnose the issue and get your heat back on. We carry common parts and work efficiently to minimize downtime. If you are considering switching from a furnace to a more efficient system, ask us about heat pump options for year-round comfort.
When repair costs start adding up or your furnace has reached the end of its life, we help you select and install a high-efficiency replacement that fits your home and budget.
Regular furnace maintenance is the best way to prevent unexpected breakdowns. Our tune-up service includes filter replacement, safety checks, burner cleaning, and a full system inspection.
Our Approach
We diagnose accurately and repair honestly. When we say your furnace needs a part, it actually needs that part. Our goal is to keep you warm and safe — not to pad a bill.

Furnace Repair & Installation FAQs
My furnace runs but blows cool air — what is wrong?
The usual causes are a dirty filter tripping the high-limit switch, a failed igniter or flame sensor, or a cracked heat exchanger. The last one is a safety issue: if you also smell exhaust or your CO detector sounds, shut the furnace down and call us.
What does a furnace repair typically involve?
Common repairs include igniters, flame sensors, capacitors, and blower motors. We quote the repair price before we start, so you decide with the number in front of you.
How often should I change the furnace filter?
Every one to three months during heating season — monthly if you have pets or a dusty environment. A clogged filter is one of the most common causes of no-heat calls.
Is a heat pump better than a new furnace?
For many homes with ductwork, a ducted cold-climate heat pump can heat efficiently and adds air conditioning. Natural-gas customers often keep a furnace or pair one with a heat pump. We give you both options and the operating-cost comparison.
