JAG Heating & Air is a local HVAC company for homeowners, landlords, property managers, and commercial clients across Medford, Jackson County, and the surrounding Rogue Valley. Whether your system stopped working this morning or you are planning a full replacement, we handle the heating and cooling work that keeps your building comfortable through every season. When you call us, you reach the people who actually show up.
We are available every day from 7 AM to 10 PM. Know the price. Know the arrival window. Know your technician.
Dealing with a furnace that won't keep up or an AC that can't cool? Those calls make up the bulk of what we do, and experienced HVAC technicians on every call means the diagnostic work gets done right the first time.
When a technician arrives, the first step is a full system check. For an air conditioner that has stopped cooling, common findings include low refrigerant from a slow leak, a failed capacitor, or a blower motor that is not moving air through the coil efficiently. For a furnace that won't fire, the culprit is often a worn igniter, a dirty flame sensor, or a pressure switch that has gone out. Heat pumps can fail in heating or cooling mode for different reasons, and a proper diagnosis covers both the refrigerant circuit and the reversing valve before any parts are ordered.
We explain what we find before any work begins, and you get a clear price before we proceed. We'll find the fault and set it right.
No heat in the middle of a cold night or no cool air on a Medford summer afternoon are not situations that can wait a week for an appointment. Emergency calls are answered every day from 7 AM to 10 PM, and same-day service is often available when you call early in the day.
We take urgent calls seriously. A technician can often be dispatched the same day a call comes in, whether the issue is a furnace that quit overnight, an AC that stopped cooling during a heat event, or a heat pump stuck in one mode. Call us and we'll walk you through your options.
From aging systems to brand-new installs, we cover the full range of HVAC replacement and installation work. That includes central air conditioning, gas furnace installation, heat pump systems, and ductless mini-split setups for homes or commercial spaces that need a flexible solution.
Before anything is scheduled, we help you understand what size and type of system fits the space. An oversized unit cycles on and off too quickly and leaves rooms uncomfortable. An undersized one runs constantly and still falls short. We keep you informed from diagnosis to final test so that by the time the new equipment is running, you know exactly what was installed and why.
Installation work covers both residential and commercial clients. If you are replacing a system that has reached the end of its life or adding cooling to a space that never had it, call us and we'll handle the rest.
A thermostat swap is one of the more straightforward upgrades we handle, and it can solve comfort and efficiency problems without touching the rest of the system. If your current thermostat is reading temperatures inaccurately, failing to hold a schedule, or simply not communicating with your equipment, a replacement is often the right starting point.
We install standard programmable thermostats as well as smart controls including Nest, Ecobee, and similar systems. The installation stays on the low-voltage control side of the equipment. We configure the new thermostat to match your system type, walk you through the settings, and confirm the equipment is responding correctly before we leave. One call brings a technician to your door.
Leaking ductwork is one of the more common causes of uneven temperatures and higher energy bills in Medford homes. When conditioned air escapes into an attic or crawlspace before it reaches the rooms it was meant to serve, the system runs longer and still does not deliver the comfort you expect.
We inspect ducts for leaks, disconnected sections, and damage, then seal or repair what we find. In cases where the ductwork is too far gone to seal effectively, we handle full duct replacement as well. Airflow and uneven-temperature complaints are a common reason we start with a duct inspection before recommending any equipment changes. We protect your floors and finishes while we work, and we leave the space the way we found it.
What makes this service different is straightforward: the air inside a home can carry particles, odors, and humidity imbalances that a standard filter does not address. Whole-home air filtration systems, air scrubbers, and UV air purifiers are installed directly into the HVAC system and work with every cycle the equipment runs.
We install whole-home air purifiers, UV air purifiers, air scrubbers, and whole-home humidifiers. If indoor air feels stale, if odors linger, or if someone in the household is sensitive to airborne particles, an air quality upgrade is worth a conversation. Wildfire smoke seasons in the Rogue Valley have made filtration upgrades a practical concern for many households in this area, and we cover those solutions in more detail in the regional services section below.
Scheduling a tune-up before the season changes is the most straightforward way to catch a small problem before it becomes a failed system in the middle of a heat wave or a cold snap. A spring AC tune-up covers coil cleaning, refrigerant level check, capacitor and contactor inspection, and a blower check. A fall furnace tune-up covers the igniter, flame sensor, heat exchanger, and filter.
Medford's summers run hot and dry, and the cooling season can arrive quickly. Getting the system checked in spring means you know it is ready before temperatures climb. Call us and we'll walk you through your options for scheduling a maintenance visit that fits your calendar.
Jackson County's climate shapes which HVAC services matter most here. Medford summers are hot and dry, wildfire smoke is a recurring seasonal reality in the Rogue Valley, and the regional push toward electrification has made heat pump installations increasingly common. The three services below reflect what is actually driving calls in this area right now.
Many Medford homes were built during a period when the mild marine climate made central air conditioning feel unnecessary. That calculus has shifted after recent record heat events, and first-time cooling installations are now among the most common jobs we handle in the area.
For homes with existing ductwork, a central air conditioning system is often the most straightforward solution. For homes without ducts, or for additions and spaces that were never connected to the main system, a ductless mini-split installation delivers cooling and heating without the need to run new ductwork through finished walls and ceilings. We assess the space, recommend the right approach, and handle the full installation from start to finish.
During wildfire season, the air quality in the Rogue Valley can deteriorate quickly. Standard HVAC filters are rated for dust and debris, not for the fine particulate matter that smoke carries. A filter rated MERV-13 or higher captures a significantly larger share of those particles, and upgrading the filtration in your system is one of the more practical steps a household can take before smoke season arrives.
We assess whether your existing system can support a higher-rated filter without restricting airflow, and we recommend the right upgrade path based on what your equipment can handle. In some cases, a dedicated whole-home air purifier or air scrubber installed in the duct system is a better fit than a filter upgrade alone. We explain the options and let you decide.
A heat pump handles both heating and cooling in a single system, moving heat rather than generating it. In Medford's climate, where winters are relatively mild compared to inland mountain regions, a heat pump performs efficiently across most of the heating season without the need for supplemental backup heat on all but the coldest days.
We install heat pumps as replacements for aging gas furnaces and as first-time installs in homes that are adding central heating and cooling at the same time. Ductless heat pump options are also available for spaces that need independent temperature control. If you are weighing a heat pump against a traditional system, call us and we'll walk you through what makes sense for your home or building.
Doing HVAC work right matters, and we'll help you get it right, whether the building is a single-tenant office, a multi-unit property, or a retail space. We work with property managers and commercial clients across Medford and Jackson County on repair, maintenance, and installation.
Commercial HVAC systems run harder and on tighter schedules than residential equipment, and a failed system in a commercial space affects tenants, customers, and operations. We handle commercial AC repair, commercial heating repair, seasonal commercial maintenance, and full system replacement. Built for homeowners. Ready for property managers. Ready for your system.
When the technician arrives, the real work begins with a full diagnostic. You get a clear explanation of what was found and a confirmed price before any repair or installation work is scheduled. There are no decisions made without your sign-off first.
For repair calls, pricing is confirmed on the phone before we schedule. For installation and replacement projects, we walk through the scope, the equipment options, and the price before anything is ordered. Know the price. Know the arrival window. Know your technician.
We serve Medford as our primary area and cover communities throughout Jackson County, including Ashland, Central Point, Jacksonville, Eagle Point, Talent, Phoenix, White City, and Rogue River. If you are in the Rogue Valley and are not sure whether your address is covered, a quick call will confirm it. Most of Jackson County falls within our service area, and we work across a range of property types and system configurations common to the region. Call (678) 824-6361 and we will confirm coverage at your address.
Call (678) 824-6361 and describe what your system is doing. We ask a few questions to understand the situation, confirm your address is in the service area, and let you know what same-day availability looks like. Same-day appointments are often available for urgent calls, especially for no-heat and no-cool situations. The sooner you call, the more scheduling options we have for that day.
Yes. We take calls every day from 7:00 AM to 10:00 PM, including Saturdays and Sundays. Weekend calls are handled the same way as any other day, and same-day service is often available when you call early. If your system is down on a weekend and you need it looked at, call (678) 824-6361 and we will tell you what is available.
It helps to know the make and model of your system if that information is accessible, as well as a general description of what the system is doing or not doing. Let us know whether the problem is with heating, cooling, or both, and whether the system is running at all. The more detail you can share on the call, the better we can prepare the technician before they arrive.
We take down the details of your situation, confirm your address and availability, and get a technician scheduled. You will know the appointment window before we hang up, and we confirm the visit before the technician heads out. From there, the technician arrives, runs a full diagnostic, and explains what was found before any work begins.
The price for the service call and diagnostic is explained on the phone before anything is scheduled. If the diagnostic turns up a repair that needs to be done, the cost of that work is confirmed before we proceed. You are not authorizing anything until you have a clear price in front of you and have agreed to move forward.
Same-day service is often available, particularly for no-heat and no-cool situations and for calls that come in earlier in the day. We cannot guarantee a same-day slot for every call, but we make every effort to get urgent situations handled quickly. Call (678) 824-6361 and we will tell you honestly what the schedule looks like.
Turn the system off at the thermostat to avoid putting strain on a unit that is not operating correctly. Check the filter and the circuit breaker to rule out simple causes, then call us. We handle no-heat and no-cool calls every day from 7:00 AM to 10:00 PM, and same-day appointments are often available for urgent situations.
Warm air blowing from the vents when the AC is running, weak airflow from registers, a system that turns on and off in short bursts, or unusual noises like banging or squealing are all signs that something is wrong and getting worse. A system that smells like something is burning or overheating should be shut off and looked at right away. These problems do not resolve on their own, and catching them early typically means a smaller repair.
In most cases, yes. The technician needs access to the equipment, which usually means the interior air handler or furnace as well as the outdoor unit. If you cannot be home, arrangements can sometimes be made to leave access, but we recommend discussing that on the call so we can confirm what the technician will need to reach. Some jobs require a walkthrough or a conversation with the homeowner before work can begin.
