Edmiston Heating has been Auburn's locally owned heating and cooling contractor since 1994. For over 30 years, we have served residential homeowners, landlords, property managers, and light commercial clients across Androscoggin County and the surrounding communities. Family-owned. Locally rooted. Comfort is our business.
When your system goes down or you need a new installation done right, same-day HVAC service is available. Call (207) 548-5534 for a quote or to schedule service.
Keeping a home comfortable starts with a system that runs right, and that is exactly what we focus on every day. Our work covers the full range of heating and cooling needs: AC repair and service, heating and furnace repair, heat pump work, complete system installation and replacement, ductwork repair and sealing, thermostat and smart-control installation, indoor air quality and air filtration, seasonal maintenance, and emergency service when you need someone fast.
We work with residential homeowners, rental property owners, landlords managing multiple units, and small commercial clients. Whatever the property type, we approach every job the same way. Clear communication from the first call to the final test is how we operate, and every customer knows what is happening with their system before we leave the job.
Whether you need a quick repair or a full system replacement, we handle the everyday heating and cooling work that Auburn and the surrounding area depend on. Here is what that looks like in practice.
When the air conditioner stops cooling or quits altogether, we diagnose the problem at the unit. That means checking the condenser, compressor, refrigerant levels, and airflow to find out exactly what went wrong. Whether it is a refrigerant leak, a failed component, or an airflow issue, we get to the root of it and fix it correctly. You can expect a clear explanation of what we found and what it takes to get your system running again. Your system is in good hands with us.
No heat in the house is one of the most urgent calls we take, especially during a Maine winter. We diagnose furnace problems from the ground up: furnace not heating, blowing cold air, cycling on and off, or not turning on at all. We also handle furnace tune-ups and inspections to keep heating systems running efficiently before the cold season hits. Catching a problem in October is a lot easier than dealing with it in January.
Heat pumps are becoming more common across Maine, and we service them year-round. If your heat pump is not heating in winter or not cooling in summer, we troubleshoot the whole system to find the issue. We also perform heat pump maintenance to keep efficiency up and extend the life of the equipment. Maine's climate puts real demands on heat pump performance, which is part of why cold-climate models have taken off here.
When a system has reached the end of its useful life, we handle the full replacement from equipment selection through installation. That includes central air installation, heating system replacement, and full HVAC system upgrades for both residential and commercial properties. We size the equipment to the building so it runs efficiently from day one, not just the first week.
Leaky ductwork wastes energy and creates uneven temperatures throughout the house. Some rooms too warm, others too cold, and the system running longer than it should. We repair and seal ductwork to restore proper airflow and help the system work the way it was designed to. It is one of the most cost-effective improvements we make on older homes. Reach out and we'll start at the unit.
A thermostat replacement is a small job that makes a noticeable difference. We install programmable and smart thermostats that give you better control over your comfort and your schedule. If you want to set temperatures by time of day or manage the system remotely, we can get that set up and walk you through how it works.
The air inside a home can carry dust, allergens, and other particles that circulate every time the system runs. We install whole-home air filtration systems and air purifiers that work with your existing HVAC equipment to improve what you are breathing every day. It is a straightforward addition that makes a real difference, especially in homes with allergy sensitivities or older ductwork.
Annual HVAC maintenance is the single best way to avoid emergency calls. We inspect and tune up both heating and cooling systems so they are ready before the season changes. A pre-season tune-up catches worn parts, dirty components, and developing issues before they become breakdowns. We work with homeowners and property managers who want their systems checked on a regular schedule.
Androscoggin County winters are long and genuinely cold. Summers are short, and while they can bring some humidity, the heating season is where local HVAC systems earn their keep. Choosing and maintaining the right equipment for this climate is not a minor detail. We check the furnace. We check the AC. We leave it running right.
In Auburn, a furnace failure in January is not an inconvenience. It is an emergency. Gas and propane forced-air furnaces are the backbone of heating in this region, and when one goes down in the middle of winter, we move fast. We diagnose the problem first. If the furnace can be repaired cost-effectively, we repair it. If the equipment has run its course, we walk you through replacement options and handle the installation. We take pride in the HVAC work we leave behind, and that starts with making sure every furnace job is done to last. Give us a ring and we'll take care of it.
Modern cold-climate heat pumps are rated to perform at temperatures well below freezing, which makes them a genuinely practical option for Maine homes. They have become a fast-growing upgrade across Androscoggin County, often paired with existing heating systems to reduce fuel use during milder stretches of the heating season. We size and select the right unit for the home, including ductless mini-split systems for homes without existing ductwork. Whether it is a new installation or an addition to an existing system, we handle the full job.
When a furnace runs hard through a Maine winter, it pulls moisture out of the indoor air. That dry air causes discomfort, static electricity, and over time it can damage wood floors, trim, and furniture. A whole-home humidifier installed on the existing HVAC system adds moisture back automatically, keeping indoor humidity at a comfortable level without portable units scattered around the house. We size the humidifier to the home and tie it into the system so it works in the background without any extra effort on your part.
No matter what is going wrong with your heating or cooling, we want to hear from you today. System not turning on, no heat in the house, AC stopped working, furnace down in the middle of a cold snap. These are the calls we take seriously and respond to fast. Same-day HVAC service is available for both residential and commercial customers, including rental property managers who need a quick response to keep tenants comfortable.
Being local means we are easy to reach and easy to work with. When you call, you get a real answer from someone who knows the area and can get a technician to you without delay. We'll have your system running again in no time.
We have served this area long enough to know what works, and we have built our schedule around the full range of customers who need reliable HVAC service. For homeowners, that means year-round comfort and a system that holds up through every Maine season. For landlords and property managers, it means dependable scheduling, clear communication, and work done right so tenants stay warm in winter and cool in summer without callbacks. For small commercial clients, including offices and retail spaces, it means commercial heating and cooling service from a contractor who shows up when scheduled and gets the job done.
Not the biggest outfit in town. Just the most reliable. Always on time.
We built this business around HVAC work like this, starting in Auburn in 1994 and growing steadily by doing the job right every time. Over 30 years later, we are still here, still locally owned, and still personally accountable for every job that goes out under our name. All work is performed by qualified HVAC technicians who know this equipment and take the work seriously.
We serve Auburn as our home base, and we regularly work throughout the wider area including Lewiston, Minot, Poland, Mechanic Falls, Leeds, and Turner. Clear communication from the first call to the final test is not a slogan. It is how we have kept customers coming back since 1994. We'll have your system running again in no time.
Auburn is where we are based, and it is where most of our calls come from. We also serve Lewiston, Minot, Poland, Mechanic Falls, Leeds, Turner, and the broader Androscoggin County area. If you are nearby and need heating or cooling service, call us and we will get you scheduled.
A no-heat situation in a Maine winter, a system that has shut down completely, or an AC failure during a heat wave all qualify as HVAC emergencies. Same-day service is available for urgent calls, and we move quickly when the situation demands it. Call (207) 548-5534 and we will get a technician to you as fast as we can.
The technician inspects the full heating system, checks the heat exchanger, tests the controls and ignition, and identifies the specific fault causing the problem. You get a clear explanation of what was found and a straight price before any repair begins. Once the work is done, we run the system through a full test to confirm it is heating correctly and operating safely.
We start at the unit itself, checking the components most likely to cause the symptom you described: controls, refrigerant levels, heat exchanger, blower motor, airflow, and so on. We do not guess and replace parts hoping something works. We diagnose the actual fault first, then explain what we found before we touch anything.
Common signs include rooms that are consistently too hot or too cold, a system that runs constantly without reaching the set temperature, higher energy bills without a clear cause, and unusual noises during operation. An aging system may also require more frequent repairs. If you are noticing several of these at once, it may be time to talk through whether a repair or a replacement makes more sense.
If some rooms are comfortable while others are not, ductwork is often a contributing factor. Leaky or poorly sealed ducts allow conditioned air to escape before it reaches the rooms that need it, which creates uneven temperatures even when the equipment itself is working fine. We inspect both the system and the duct distribution to figure out where the problem actually lives.
Duct sealing closes gaps, cracks, and loose connections in the duct system that allow conditioned air to escape into unconditioned spaces like attics and crawl spaces. The result is better airflow to every room, more even temperatures throughout the home, and less work for the equipment overall. It is one of the most cost-effective improvements we make on older homes in this area.
Uneven temperatures usually come down to airflow imbalance, duct leaks, or a system that is not sized correctly for the layout of the home. Blocked vents, a dirty filter, or a damper that is closed or stuck can also cause a single room to fall out of range. We inspect the system and the ductwork to find the actual cause rather than guessing.
Banging or clanking usually points to a loose or broken component inside the unit. Squealing often indicates a belt or bearing issue. Rattling can mean debris in the system or a loose panel. None of these sounds should be ignored, because what starts as a minor noise can become a more expensive failure if the underlying cause is not addressed. Call us and describe what you are hearing.
After any repair or installation, we run a full operational test: we cycle the system through heating or cooling mode, check airflow at the registers, verify the thermostat is responding correctly, and confirm the system reaches and holds the set temperature. We do not consider the job done until everything is working the way it should.
We start by assessing the existing system and the building it serves, then recommend equipment sized correctly for the space. We give you a clear estimate before any work begins. Installation is performed by qualified HVAC technicians, and we run a complete system test before we leave. For larger jobs, we also handle the permitting process so the work meets current code.
Additional costs typically come from parts that need to be ordered, equipment that is difficult to access, or a repair that reveals a secondary problem once the system is open. We communicate any of those situations before adding to the scope of work. You will never find a charge on your bill that we did not discuss with you first.
Modern cold-climate heat pumps are rated to deliver reliable heating output at temperatures well below freezing, which makes them a practical option for Maine rather than just a warm-weather technology. They handle both heating and cooling from a single system, which reduces the load on a furnace and lowers energy costs over time. We install both ducted whole-home systems and ductless mini-split configurations for homes without existing ductwork.

How do I know whether to repair or replace my furnace?
The general rule is to weigh the cost of the repair against the age and remaining life of the system. A furnace that is 15 to 20 years old and needs a major repair is often a better candidate for replacement than one that is 8 years old with a straightforward fix. We walk through the numbers with you honestly and give you a clear estimate for both paths so you can make the call that makes sense for your situation.
What does a seasonal tune-up actually cover?
Each visit includes a full system inspection, filter check, refrigerant level verification, airflow testing, and a review of all controls and safety components. For furnaces, we also inspect the heat exchanger and test the ignition system. The goal is to catch anything that could cause a breakdown before the season puts heavy demand on the equipment.
Why is one room in my home hotter or colder than the rest?
Uneven temperatures are usually a sign of a ductwork problem, an airflow restriction, or equipment that is not sized correctly for the space. Leaking or poorly sealed ducts are a common cause, and so is a dirty coil or a blower that is not moving enough air. We diagnose the cause at the unit and in the duct system and tell you exactly what it will take to even things out.
Same-Day and Emergency Availability
We offer same-day HVAC service for urgent situations, including no-heat calls in the middle of a Maine winter. When your system goes down, we move quickly to get it running again.
Is same-day service available for heating and cooling emergencies?
Yes. Same-day HVAC service is available for urgent situations, including no-heat and no-cool calls. We understand that a furnace failure in a Maine winter is not something you can wait on, and we move quickly when the situation demands it. Call us and we will get someone to you as fast as possible.
Are cold-climate heat pumps actually practical in Maine winters?
Modern cold-climate heat pumps are engineered to deliver reliable heating output even when outdoor temperatures fall to around -15 degrees Fahrenheit, which makes them a genuinely practical option here rather than just a warm-weather technology. They provide both heating and cooling from a single system, which reduces the load on a furnace and can lower energy costs over time. We install whole-home ducted systems as well as ductless mini-split setups for homes without existing ductwork.
What could cause my system to short-cycle, meaning it turns on and off frequently?
Short-cycling is one of the more common complaints we hear, and it can have several causes: a dirty filter restricting airflow, a refrigerant issue, an oversized system that heats or cools too quickly, a failing thermostat, or a problem with the control board. It puts extra wear on the equipment and raises energy costs. We diagnose the cause at the unit and explain what the fix involves before we start any work.
Upfront Quotes With No Surprise Fees
We give you a clear price before any work begins and do not start a repair or replacement without your approval. Clear communication from the first call to the final test is how we do business.
How do ductwork leaks affect my energy bills?
Leaking ducts allow conditioned air to escape into unconditioned spaces like attics, crawl spaces, or wall cavities before it reaches the rooms you are trying to heat or cool. The system runs longer to compensate, which drives up energy costs and puts extra wear on the equipment. Sealing the duct system is one of the more cost-effective efficiency improvements available for a home with existing forced-air heating and cooling.
Do I need to be home when the technician arrives?
For most repairs and installations, yes. Having someone present allows the technician to explain what they found, get your approval before starting work, and walk you through the results when the job is done. For routine maintenance on a commercial property or rental unit, we can often coordinate with a property manager or on-site contact. Just let us know the situation when you call.
Work Performed by Qualified HVAC Technicians
Every job we take on is handled by qualified HVAC technicians who know the equipment and know this climate. We take pride in the work we leave behind.
What can I expect when it comes to pricing and estimates?
We give you a clear price before any work begins. The technician inspects the system, explains what they found in plain language, and tells you what the repair or replacement will cost before starting. We do not begin work without your approval, and if something unexpected comes up during the job, we stop and talk it through with you before moving forward.
What are the signs that my AC or furnace may need to be replaced soon?
Age is the most reliable indicator. Most furnaces have a useful life of 15 to 20 years, and most central AC systems run 12 to 15 years with proper maintenance. Beyond age, watch for frequent repairs, rising energy bills without a clear cause, uneven heating or cooling, and a system that runs constantly without reaching the set temperature. Any of those patterns is worth a call to have the system evaluated.
Why would a whole-home humidifier make a difference compared to a portable unit?
Portable humidifiers treat a single room at a time and require regular refilling and cleaning. A whole-home humidifier installs directly into the HVAC system and delivers consistent humidity to every room automatically, controlled through the thermostat. In a Maine home running forced-air heat for five or six months of the year, the difference in comfort and air quality is noticeable.
Every home and every system is a little different, so call us at (207) 548-5534 and we will talk through exactly what your situation calls for.
