I needed prompt service as I had no heat during a cold snap. I told Charlie I needed a new furnace installed asap and he made sure it was done the day.

I called on Monday and they were able to fit me in on Wednesday. They arrived on time, were pleasant, efficient, and clearly explained the problem with our A/C system. I will absolutely call them again.

Very easy to work with and the staff was extremely professional. They replaced a freon based AC/heating unit utilizing today’s improved technology. From start to finish it was a pleasure working with Marshall Mechanical.

Charley came out promptly when we asked, spec'd the project, gave us a quote quickly and the work was scheduled within 10 days. Guys onsite for the project did a great job, moved vents just as needed and actually made the return air duct vastly quieter. Excellent work all around. Many thanks.

Charlie Marshall and his team were responsible for the installation of many HVAC systems 5+ years ago for a builder that owned the rights to a cul-de-sac community in southern New Hampshire. I happen to be one of those homes. Charlie and his team installed a high efficiency HVAC system in an uninsulated attic which should never have passed inspection being that those systems require double ventilation or an insulated attic. I have been unable to find a reputable company to service this unit in all those years because of parts that were used that have been recalled or the fact that the system does not meet compliance. I have called Charlie Marshall on his personal cell phone many times over the years and have not received a phone call to discuss this matter. Therefore, I find this review to be extremely appropriate to give buyers a buyer. Beware of what you are purchasing and installing in your home since this individual doesn’t seem to install things to code. This might be a one off, but Charlie had every opportunity to fix the issue and he did not.

Charlie was extremely responsive with our family when our system failed and needed to be replaced with incredible urgency in frigid weather. He was both professional and kind. Highly recommend!

As new homeowners, we have had a lot to learn and Charlie and Joey have been incredibly helpful. They’ve addressed our issues thoroughly and carefully and have answered questions clearly. We’ve also been impressed with how quickly they’ve come out (48 hours at most). Highly recommend!

Charlie and his team really came through for me and my family, Friday night sometime our furnace started tripping the rollout switch after many phone calls I was given the number for Marshall Mechanical , Charlie made a trip over Saturday evening to confirm our fear that it was time for a new furnace. We were given options and a clear explanation of what we’d be getting and then first thing Monday morning they swapped our unit out . Very friendly and professional and left zero mess . I hope to only need their services for routine maintenance now. Thanks guys Merry Christmas

Frequently asked questions
-
Is GigoPro free to use?
Yes. Browsing businesses, reading reviews, and comparing providers is free for everyone. Business owners can create a basic listing at no cost.
-
How do you verify businesses on GigoPro?
Every profile goes through moderation before it appears in search. We check that the business is real, active, and matches the category it claims. For regulated trades, we look for proper credentials, and inactive listings are hidden automatically.
-
How do I choose the right contractor?
Start with ratings and recent reviews, then compare the services offered, location, and response time. Contact two or three providers, ask for written estimates, and compare what each quote includes — not just the bottom line.
-
Can I list my business on GigoPro?
Yes. Create a free business profile to reach local customers searching for your category. You can update your services, photos, and contact details anytime, and customers can book you directly from your profile.
-
How often is the HVAC directory updated?
Business owners update their own profiles. Our team also refreshes hub pages and removes inactive listings to keep search results current. This page, for example, is reviewed and updated monthly.
-
How often should I have my air system serviced?
At minimum, once a year — ideally a spring tune-up before cooling season and a fall check-up before heating season. Systems that run year-round, older units, and commercial systems often benefit from professional service twice a year.
-
Repair or replacement — how do I decide?
Ask each contractor for both a repair quote and an honest assessment of the unit's remaining life. As a general rule, if a repair costs more than a third of a new system, or your equipment is past its expected lifespan and breaking down repeatedly, replacement is usually the better value. Get two or three opinions before a decision this large.
-
Can companies on GigoPro handle emergencies?
Yes — many list emergency and same-day service in their profiles, with stated after-hours policies. Open the profile and check the response-time and availability information before you need it; in a real emergency, filter for companies that explicitly offer 24/7 service.
-
How much does service cost?
Costs vary by region, system type, and job — there is no honest single number. Reputable contractors provide written estimates after inspecting the system, and comparing two or three is the best way to understand what your job should cost.
-
Can I leave a review after booking through GigoPro?
Yes. After your job is done, you can rate the company and describe your experience. Verified reviews from recent jobs are exactly what helps the next homeowners in your city choose well — and what keeps listed professionals at their best.
