The heating repair reviews that say the most

How we picked these: the most specific reviews first, the ones that name the problem, how it turned out and how they were treated. Then the newest, spread across towns.

5 out of 5 stars

The estimator/sales person and technicians were top notch. The estimator worked with me on the system requirements and the cost of a new heat pump system. My old system was 20 years old so that the heat pump and inside air handler had to be replaced. Also replaced the thermostat for good measure. The technicians did an excellent job with the install, neat and professional. The system has been working really well. Overall, I believe that I received excellent service at a reasonable cost.

We had no heat and found SwiftPro. I received a call within an hour of my request Jay set up an appointment for the following morning. Moises was very professional when he arrived and was able to find out what the problem was. He was polite, diligent, and efficient and he was able to make our system work for a few days until the part arrived. What I especially liked is before he arrived they posted a picture of him to me via text letting me know who to expect at my front door. …

That gave me a wonderful piece of mind!

Five stars all around.👍

In the middle of one of the coldest weeks this winter, a small gas leak one evening resulted in immediate shut off - and a loss of any hot water and heating along with it. After a great experience with SwiftPro last summer to fix our HVAC (shout out to Elvis, who was an incredibly responsive and thorough technician!) we gave them a call and were responded to immediately.

Our technician Tyson came out the following day. He was friendly, courteous and went out of his way to find and pick up the replacement part we needed, transparently communicating expectations and pricing throughout the entire process. …

It’s rare to have your problem resolved in a single appointment, but Tyson did just that so we could restore heating and avoid another cold evening (with a toddler, one night was enough..)

We couldn’t be happier with the service we continue to receive from the SwiftPro team!!

I can’t say enough good things about SwiftPro. I have a really old system, and every other company I called immediately tried to sell me a full replacement which really isn’t an option for me. SwiftPro actually listened to what I wanted and worked with what I had. They gave me a repair option, were honest about everything, and got my system through one of the coldest times of the year. It felt good working with people who genuinely cared instead of just trying to make a sale. …

Companies you can truly trust are hard to find, and SwiftPro is one of them. I’ll absolutely keep using them and recommending them to people I care about.

Moises was absolutely amazing! He worked for hours to install our new heater since our died and we were days without heat 🥲. He was careful with installation and patient with us in explaining everything about the heater and the filters we needed. He told us we can reach out to him if we have any problems or questions. Thank you Moises!!

Moises showed up on time and was very thorough and quick. He diagnosed our problem and Tyler came in and gave us a great quote on a new unit. They came back and installed it the next day! They came through for us and I am very happy with their service. Will definitely use them again!

We found SwiftPro by googling and learned that their service district includes Fauquier County. Elvis Diaz, their service tech, was amazing. He diagnosed the multi-year problem we had with our HVAC quickly, which the HVAC installer repeatedly missed! The issue was a communication problem that knocked out the HVAC during a thunder storm. The installer kept replacing circuit boards and other parts, some at our expense I think, others under warranty. The installer completely overlooked the wiring and it was a mess, Elvis found. …

Elvis replaced the wiring the same week as his initial visit and our HVAC was fixed and it keeps working during and after subsequent thunder storms. We are so grateful to Elvis and Swiftpro!

I recently had my heat pump replaced by SwiftPro Heating, Cooling & Plumbing, and the entire experience was excellent from start to finish.

From the sales process to the installation, everything was smooth, professional, and well organized. The price, warranty, and reputation they offered provided greater value than the other quotes I received.

Moises and his installation team were outstanding — knowledgeable, respectful, and very professional throughout the entire job. They took great care to cover and protect all work areas while installing the new system, and when the job was completed, everything was cleaned up perfectly. …

The workmanship and attention to detail were impressive. I highly recommend SwiftPro Heating, Cooling & Plumbing to anyone looking for quality HVAC service and installation.

I called SwiftPro for the first time, and within 24 hours a technician was here. Everyone I encountered on the phone and here was efficient, courteous, attentive, and, well, it was just a pleasure. I've had only the one experience, but the technician is returning next week for a much bigger job. I have complete faith.

Ellen D. · February 2026Angi (Chantilly profile) ↗

What this job usually involves

Winter calls are mostly a furnace blowing cold air, a house stuck at 66 on a cold night, a system that turns on and off every few minutes, or a heat pump buried in ice. On a gas furnace the usual culprit is a dirty flame sensor or a failing igniter. Short cycling tends to be a clogged filter, a dirty flame sensor or a furnace too big for the house. A heat pump that stays iced points at the defrost board, a sensor or low refrigerant.

The diagnostic covers the whole system: burners, igniter, flame sensor, heat exchanger, venting, the electrical side and the airflow. We inspect the heat exchanger on every heating visit, because a cracked one can put carbon monoxide in the air the furnace blows around the house. You get the repair price in writing before work starts, and flame sensors, igniters, capacitors and many motors are on the van. We put Trane first as a Trane Comfort Specialist, also install Carrier, Rheem and Mitsubishi Electric, and repair American Standard, Lennox, Goodman, Amana, Daikin, York and the rest, plus gas boilers.

Questions people ask

Why is my furnace blowing cold air?

On a gas furnace it's usually a dirty flame sensor or a failing igniter: the burners light for a few seconds or not at all while the fan keeps running. On a heat pump, a few minutes of cool air on a frosty morning is the defrost cycle and is normal. Cool air for an hour isn't.

Why does my furnace turn on and off every few minutes?

That's short cycling. The usual causes are a clogged filter, a dirty flame sensor, or a furnace sized too big for the house. Every start is the hardest moment for the parts, so a furnace that short cycles wears out faster and never heats the house evenly. The first two are cheap fixes.

The carbon monoxide alarm went off. What now?

Get everyone out of the house and call 911 first, then call us. Carbon monoxide has no smell. A cracked heat exchanger can let it into the air the furnace blows through the house, which is why we inspect the heat exchanger on every heating visit.

How long should a furnace last?

Fifteen to twenty years for a gas furnace that gets looked at every fall. Heat pumps run in every season, so they usually land at twelve to fifteen. A furnace past fifteen with a repair over a third of the cost of a new one is usually better replaced.

Do you service boilers?

Yes: gas boiler repair and replacement, including the older hot water systems in condos and townhouses. Boilers get quoted after we see the system, because the piping decides as much of the job as the boiler does.

We had a persistent musty smell coming from our vents every time the furnace kicked on this season. SwiftPro came out, thoroughly scrubbed the duct walls, and applied an eco-friendly sanitizer. Smells completely clean now! ✨

I’ve been searching for a reasonable furnace and A/C replacement for the better part of six months for my aging systems. Swift Pro was one of my original estimates along with six other companies. I had small companies and large companies quote me for similar systems with a range of cost from $9,000 to $30,000. My preference is always to support local businesses over large corporate run companies. …

Swift Pro wasn’t the cheapest and far from the most expensive. After working with Tommy and Tyler at Swift Pro, we settled on a very reasonable price and I replaced my furnace, A/C and water heater. Swift Pro has excellent customer service, an exceptional warranty and the install team was amazing. Hopefully I don’t have to do this project again anytime soon. But if I do, I would use Swift Pro again! As a bonus, the turn around time was very fast.

Replacement for my broken gas water boiler was professionally done and in a timely manner.

The technicians knew exactly what they were doing.

The price was a bit high and I was expecting to get a small rebate but there was none.

Thanks guys

​When it came time for installation, Elijah, Hugo, and Oscar were absolute rockstars. They arrived on time, worked remarkably fast, and maintained complete efficiency throughout the entire job. What really stood out was how clean and respectful they were of my home—they left the workspace spotless when they finished.

​On top of their hard work, the team provided exceptional customer service. They took the time to clearly explain how the new systems work, walked us through everything, and answered all our questions without rushing.

​If you need HVAC or plumbing work done right, I highly recommend SwiftPro!

Edis Arevalo and Roney were also incredibly supportive, knowledgeable, professional, and effective communicators.

Justin Dubroc was punctual for the appointment, displaying professionalism and a willingness to assist. …

SwiftPro Heating, Cooling and Plumbing Responsive and Efficient service

We had just finished installing new LVP flooring when we ran into problems with two of our toilets. The handyman who reinstalled them had plumbing experience, but one toilet ended up leaking and the other wobbled. Needless to say, we needed a plumber pretty quickly.

SwiftPro Heating, Cooling and Plumbing came through for us. …

They were very responsive from the beginning, Hannah was delightful to work with, and she scheduled us fast and the process was very easy with good communication. The plumber who came out, Zabi, was professional, friendly, and knowledgeable. He explained what he was doing, answered all of our questions, and worked quickly and efficiently to complete everything we needed in a timely manner.

We also appreciated the manager working with us on volume pricing since we were installing or reinstalling four toilets. Their price was very reasonable compared with several other plumbers we contacted.

Overall, we had a very good experience with Swift Pro. They helped turn a stressful situation into a much easier one, and we appreciated their responsiveness, communication, and quality of work. We will definitely call them again and would recommend Swift Pro to anyone looking for a reliable plumber who shows up on time, communicates well, and gets the job done.

Thank you SwiftPro!

Our HVAC system quit working in the heat wave of 100 degrees. We called SwiftPro and they were quick to respond, super professional from the answering service to the team of installers. They replaced the old system we had with perfectly fitting new condenser evaporator and furnace. The work was done in one day- several hours to remove the old units with cleanliness and care and install the new one that’s working perfectly. …

During the whole operation they kept us informed.

I cannot recommend SwiftPro enough, specifically their HVAC technician lead, Efrain Aguilar. For months, we struggled with a persistent furnace issue that no one else could figure out. We had technicians visit from other companies, but we were always left without a real answer—until Efrain arrived.

From the moment he stepped in, he was a true professional. He came fully prepared and even wore shoe covers to protect our floors, which we really appreciated. …

After we explained the symptoms, he spotted the root cause almost immediately.

What truly set Efrain apart was his patience. He didn’t just tell us what was wrong; he took the time to explain exactly what caused the issue and why it was happening. He then walked us through the recommended next steps with total clarity. It didn’t feel like a standard diagnosis; it felt like a masterclass. It's clear he is incredibly knowledgeable and a master of his craft.

If you want someone who is professional, thorough, and actually knows what they’re doing, ask for Efrain at SwiftPro. Thank you for the peace of mind

Our heater broke right before a big storm, so we contacted Swift-Pro on Thursday. They were able to come out the same day for an estimate. The tech who gave us the estimate was very knowledgeable, was able to answer all of our questions, and the price on the installation was better than other estimates we’d gotten. We originally scheduled the install for Saturday, but they went above and beyond by coming out late Friday afternoon and working past close of business to get the install done so we had heat before the storm. …
