Professional Ductless Heat Pump Installation

If you want to remove air duct cleaning or maintenance from your Lowcountry home (or don’t have air ducts to begin with), let us help you choose & install the best ductless heat pump unit to fit your home’s particular needs.

Why Heat Pumps Work So Well in the Lowcountry

A heat pump moves heat instead of making it. In summer it pulls heat out of your home; in winter it runs in reverse and brings heat in. Because Charleston winters are mild, a heat pump can handle most of the heating season efficiently on its own. One system, one maintenance plan, and no separate furnace for most homes.

When a New Heat Pump Installation Makes Sense

You're adding a room, a bonus room or an in-law suite that the current system can't reach
You're building or finishing space and want efficient heating and cooling from the start
You're moving away from an older setup, like electric resistance heat or window units
Part of the house never gets comfortable and a dedicated ductless heat pump would fix it
You're replacing a failed system and want to upgrade to a more efficient heat pump

If your existing heat pump is wearing out, our heat pump replacement page walks through that decision in more detail.

How We Size and Install Your Heat Pump

The most common installation mistake is the wrong size. An oversized heat pump cools the air fast but shuts off before it pulls the moisture out, so the house feels cold and clammy. An undersized one runs nonstop and still falls behind in August. We size every system to your home's actual load.

What installation day looks like

We protect your floors and work areas and walk you through the plan
We set the outdoor unit and indoor air handler or ductless heads, then connect the refrigerant lines, wiring and drain
We check the ductwork connections and airflow on ducted systems
We start the system, test it in both heating and cooling, and set up your thermostat
We show you how it works and what to expect in the first few weeks

Install footprint	Uses existing ducts; duct repairs may be needed	Small line set through the wall; no ducts needed

 Trustindex verifies that the original source of the review is Google. My Three Sons have been a great company for years. They are our immediate call whenever we have any HVAC issues. We recently had our entire HVAC system replaced, Travis was great explaining everything to us and his team did an awesome job on the install. Everything works great and the team did an awesome job cleaning up and protecting my floors with carpet protectors. Highly recommend for anyone to get great customer service and quality work.

 Trustindex verifies that the original source of the review is Google. GREAT COMPANY - THEY PROVIDED AN HONEST ASSESSMENT OF WHAT OUR HOME NEEDED FOR MORE EFFICIENT AC AFTER YEARS OF IT STRUGGLING TO KEEP UP WITH SUMMER HEAT & UPDATED OUR SYSTEM FOR A VERY REASONABLE PRICE. HOME IS NOW MORE COMFORTABLE THAN IT EVER HAS BEEN!!

After over a year of having other AC repair company nickel and dime me with expensive repairs that never improved our AC & ultimately recommended a very expensive upgrade because they "couldnt figure it out and our system was just too small", I finally reached out to this company for a second opinion

They came and provided an assessment & pointed out basic issues with our old system and poor maintenance practices from the other company - and also recommended we not just get a bigger system. They ultimately recommended replacing old system but focusing on improving the airflow for significantly less than the other company

Trusting this company ended up being a really good decision - for the first time in 4 years our home AC is now capable of keeping up in the heat of summer, the airflow is significantly better and - this is a little thing but its the little things that matter and make great companies stand out from the good ones - they cleaned our attic so well after the installation that it looks better than it ever did before. HIGHLY RECOMMEND REACHING OUT TO THIS COMPANY, THEY ARE HONEST & CLEARLY REALLY CARE ABOUT WHAT THEY DO.

 Trustindex verifies that the original source of the review is Google. Willy is great! He was extremely pleasurable and professional. He had the unit running in a short period of time, explained exactly what the issue was and hung around to ensure the AC was properly functioning. We will definitely call My Three Son’s for any future needs.

 Trustindex verifies that the original source of the review is Google. We needed a complete replacement of our duct work, and My Three Sons were outstanding. Travis was professional, polite, and prompt in all communications, including text and email. The crew was organized and courteous and tried to leave a minimal footprint around the house. The job was done well and priced very fairly. I would highly recommend this group for any HVAC work in our area.

 Trustindex verifies that the original source of the review is Google. My Three Sons is a fantastic family-owned HVAC company. I have used them for 2 of my properties. They are always prompt, responsive, and easy to work with. Very professional work and fair pricing. Most recently, over Labor Day weekend they were able to show up within an hour of me calling on a late Sunday afternoon (holiday weekend) to address an issue with my tenant’s split units. True customer service! I always try and use local, absolutely recommend them to anyone in Charleston.

 Trustindex verifies that the original source of the review is Google. I had a service call this morning.   Willy was the technician and he was amazing.   Beyond thorough and a true professional.   I never do these reviews, but this company is outstanding.    I paid much less than expected for the time spent in my house (and in the crawl space!)    They were on time, wore booties, etc.   This may be my first and only five star review.   It’s nice to know these companies still exist!

Common Questions About Heat Pump Installation

1Is a heat pump a good choice for Charleston, SC?

Yes. A heat pump heats and cools with one system, and Charleston's mild winters let it handle most of the heating season efficiently. That makes it one of the most common and practical choices for Lowcountry homes.

2How do you know what size heat pump my home needs?

My Three Sons HVAC sizes each system to your home's actual heating and cooling load, looking at square footage, insulation, windows, sun exposure and ductwork. An oversized system short-cycles and leaves humidity behind, so correct sizing matters as much as the equipment itself.

3Can I add a heat pump for just one room or an addition?

Yes. A ductless mini-split heat pump is often the best fit for an addition, bonus room or a room the central system can't keep comfortable. Each indoor unit has its own control.

4How much does heat pump installation cost?

It depends on system size, efficiency rating, ducted or ductless design, and any ductwork or electrical work needed. We provide an itemized written quote after an in-home estimate, and financing is available.

5What comes with a My Three Sons HVAC installation?

Every installation includes the MTS Installation Advantage: a system chosen for your home rather than a sales quota, a quality control inspection after the install, an extended labor warranty and one year of free maintenance.
