“We have used A-1 in several of our homes from full AC/Furnace unit install for the entire home to repairs and more. From Boise/Meridian up to McCall, we have always had a great experience. This most recent job, Randy and his team have been especially amazing. Incredible communication, on time each appointment, install was professional and so quick. Gave us many financial options to choose from to fit our needs and they never are pushing us to do more or pay more than needed. I cannot say enough about A-1. Excellent company and team.”

Heating Services

Heating services are a crucial part of keeping your home warm and comfortable throughout the cold winter months. Whether it’s installing a new furnace or repairing an old one, there’s nothing quite like the peace of mind of knowing that your home’s heating is taken care of.

With our professional heating services, you can rest assured that we’ll get your system up and running quickly. From furnace repair to routine maintenance, or furnace replacement, our qualified heating technicians can help you keep your home warm and welcoming all season long.

Heating Repair

A broken heater causes more than discomfort. It may also lead to frozen pipes, high energy bills, and unwanted stress. If your furnace won’t turn on, makes unusual noises, or struggles to regulate temperature, we can help. Our HVAC services include diagnostics, part replacements, and system testing to catch problems early. Each repair includes a walkthrough, so you understand what went wrong and how we’re solving it.

Heating Installation

New homes and aging systems both require reliable heating installation. Our team selects units that align with your property’s size, layout, and heating demands. We replace and install gas furnaces, electric models, heat pumps and geothermal heating systems, always with a focus on long-term performance. Airflow balance and ductwork support are also integral to our process, ensuring the system operates smoothly.

Heating Maintenance

Proactive maintenance is the best strategy to prevent unexpected breakdowns and keep your furnace operating at its peak potential. Our detailed tune-up appointments involve a complete inspection of your heating equipment, cleaning of internal components, and verification of all safety controls. This regular service helps your system achieve better heat transfer, which can contribute to lower energy consumption and extend the unit’s operational life.

Heat Pump Solutions

Heat pumps serve as a flexible option for both heating and cooling. These systems move heat instead of generating it, making them a smart option in moderate climates. Our team installs and services air-source and geothermal heat pumps throughout the Greater Boise area.

Cooling Services

Cooling services are an essential aspect of home maintenance, especially during the scorching summer months. Whether for AC replacement, repair, or maintenance, it’s crucial to have a reliable service provider to keep your home cool and comfortable.

A-1 Heating, Air Conditioning & Electric understands homeowners’ needs and provides fast and efficient services to guarantee optimal AC functionality. With our expertise, you can enjoy cool air all summer long, ensuring your family’s comfort. As the top heating and cooling company serving Greater Boise, you can experience the benefits of our AC services.

Investing in our professional cooling services gives you peace of mind. In addition, it helps prevent potential AC breakdowns, keeping you cool and comfortable at all times.

AC Repair

Common issues like a faulty condenser, leaking refrigerant, or weak airflow often point to underlying mechanical problems. Our HVAC services include thorough AC diagnostics and quick repair work for these issues. If your air conditioning system is blowing warm air or won’t turn on, we’re ready to take a look. We also test for circuit breaker trips and capacitor failures that might interrupt system function.

AC Installation

We also offer AC installation in Boise. Our technicians install central air conditioners that cool the entire home without disrupting your daily routine. We assess each space to determine which unit matches your home’s size and layout. New systems include SEER-rated equipment, giving you more control over energy use and cooling power. We’ll even review the thermostat setup to help you manage indoor temperature throughout the summer.

AC Maintenance

Ask about AC tune-ups in Boise. Regular maintenance appointments are an investment in the reliability and longevity of your air conditioning. Our technicians perform detailed tune-ups that prepare your AC unit for the intense demands of the summer cooling season. This service includes cleaning the coils, checking system pressures, inspecting electrical connections, and changing the air filter. A well-maintained air conditioner operates with greater efficiency, experiences fewer breakdowns, and provides superior cooling performance.

Ductless Mini-Split Solutions

Homes without central air benefit from ductless mini-split systems. These compact units cool individual rooms while avoiding the need for extensive ductwork. Installation is quick and minimally invasive, making them a popular choice for additions, garages, or home offices. We’ll help you select the right model and place it in the room that needs it most.

Indoor Air Quality Services in Greater Boise

The quality of the air inside your home has a direct impact on your family’s health and well-being, yet it’s something that often goes overlooked. Indoor air can harbor dust, pollen, pet dander, viruses, and other invisible contaminants that circulate through your HVAC system. We offer advanced air purification solutions, including the installation of a whole-home air scrubber, to actively remove these particles and neutralize odors.

Electrical Services in Greater Boise

Electrical work requires precision, safety, and trust. Our licensed electrical contractors handle residential wiring, panel upgrades, and custom installations with care. We install everything from circuit breakers and surge protectors to lighting and ceiling fan fixtures. Our team also supports modern upgrades like electric vehicle charging stations and whole-home generator setups. We provide generator installation in Boise, plus electricians in Meridian and electricians in Nampa.

When your furnace quits on a freezing January night or your AC dies in the August heat, our licensed local technicians are ready to respond on nights, weekends and holidays.

A broken system is more than an inconvenience. It can mean frozen pipes in winter or an unsafe home during a Treasure Valley heat wave. We have kept Idaho families comfortable since 1956, and that is who answers when you call after hours. No call center runaround. No pushy upsells. Just a straight answer, an honest price before we start, and a technician who fixes it right.

Because we are licensed for both HVAC and electrical, we handle emergencies other companies have to hand off, from a furnace that trips the breaker to a burning smell at the panel. If you smell burning, hear loud grinding, or see sparks, shut the system down and call us right away.

A1 replaced my AC & Furnace plus a free water heater and did a great job. We went through the Costco program and got a shoppers credit. Genero did our estimate and came up with few options. Doug and Sam installed my equipment in a couple days. Overall very satisfied with A1 and I would recommend them to replace your system.

I was extremely impressed by your technician, Casey, and his service this morning. He came to assess my hot water heater which I assumed was the reason for my flooded basement. When he determined that the heater was operational he took the time to help me shop vac my flooded basement and even dragged out the rugs that had gotten soaked knowing that it would've been a difficult thing for me to do. I so appreciated his help. He told me that his farming background had prepared him to always do a thorough job and he certainly walked this talk. Genaro De Leon, your sales rep, was also great. He helped me to order a new heater. He didn't pressure me to buy a new one, but since mine is 13-years-old, I felt it was time. This 72-year-old will use your services whenever possible. Thank you so much.

It was good to have a Generac qualified service technician to maintain my generator. The tech was professional in knowledge and conduct, and corrected issues created by a tech that was not qualified. I also appreciate the fast scheduling to get it done. I have made them my preferred dealer. Highly recommend A1.

A-1 has been great to work with. We purchased a new furnace and air conditioner many years ago from A-1, we've had A-1 maintain them twice a year since. Gus came to do a maintenance on them. Very nice guy, explained what he did and was thorough. Would definitely recommend A-1 Heating and Air Conditioning!

I highly recommend A-1 , Air Conditioning & Electric. Early in 2026, I randomly called A-1 to determine the feasibility of running a natural gas line for a new fireplace installation. That installation was a little complicated having to spice off a flexible gas line in the garage attic. The job was expertly completed. I was impressed with the professionalism and engineering approach to assure functionality and safety concerns. In late September of 2026, I thought I was noticing a very faint smell of natural gas in the garage, but really wasn't sure. As a matter of precaution I called A-1 to inquire about having them check it out. Without hesitation, they directed me to immediately call the emergency line for Idaho Gas. I did. Idaho Gas was at my house within minutes, determined there was a serious gas leak (source unknown) in the garage attic and then shut the gas off to the house completely, with instructions to hire a qualified service to find the source and do the repairs. I contacted A-1 to report that Idaho Gas had confirmed the gas leak. A-1 sent technicians right away (within 30 minutes). They skillfully located the source of the leak. It had nothing to do with the fire place gas line work they had accomplished earlier in the year. A couple of weeks before, I had a new roof installed. Two roofing nails had inadvertently punctured the flexible gas line in the garage attic! The technicians were skillfully able to make the repairs and safely restore natural gas service to the house. All this happened in the same day! I am I indebted to A-1 Heating, Air Conditioning & Electric and the Idaho Gas and their rapid response to address my natural gas emergency. The potential for a far worse outcome was avoided. I wrote this review in so much detail to impress upon the reader my lessons learned about what to do and who to contact when even the faintest hint of a natural gas leak you might one day detect in your home: 1. Predetermine an HVAC, plumbing, or electrical company to call in emergencies, not after the emergency happens. 2. When you call A-1 you will be talking to a real experienced person who sincerely cares about you, not a robot answering service personality that doesn't. 3. You can expect from A-1 a highly qualified project manager and experienced technicians to take care of you right every time. 4. When dealing with natural gas, you have to trust the safety of your home and family to them. Understand the value of what they do every day to assure themselves any you nothing was lift to question.

I greatly appreciated the personal interaction with the technician. I have my quirky ways and preferences, and the technician was very patient and understanding of my preferences in a non-judgmental way. This is a rare gem to have real personal customer service.
