304 Heating Cooling Plumbing

Energy-Efficient Heating & Furnace Installation

Keep your home safe and warm all winter long with a new, energy-efficient heating system installation from 340 HVAC. Whether you are building a new home or upgrading an old, inefficient furnace, we help you select and install the perfect heating solution tailored to your space and budget. Modern heating systems can dramatically lower your monthly utility costs while providing superior, consistent airflow.

It may be more cost-effective to replace your unit rather than continually paying for repairs if:

  • Your furnace or heating system is over 15 years old.
  • Your heating bills are steadily climbing despite regular maintenance.
  • The cost of a single repair is more than 50% of the cost of a brand-new system.

We were very impressed with the work the 304 team did to replace our heat pump, furnace, and A/C systems. We have an air handler in a very tight attic space, and 304 was up to the challenge. They took the old unit out in pieces and replaced it with a bigger and more efficient modulating Trane unit without having to modify our ceiling or attic. We couldn't be happier with the installation. There were eight or nine guys working on the job, and all of them were knowledgeable, hardworking, and polite. We highly recommend the 304 team for your HVAC needs.

I had a bad situation where my cathedral ceiling was wet in several places and was making black looking spots all over. 304 came and did a complete diagnostic and identified the problem. They were so quick and professional! They didn’t try to sell me anything either. I miss good honest people that know what they are doing. You could definitely tell that these men had the experience. So, if you need some help with your heating or cooling I highly recommend 304 !

Initially, I did not reach out to 304 because they appeared to be located too far to service my new residence in Charleston. I was wrong! After several attempts to secure quotes from other more 'local' service providers in Charleston, I reached out to 304 and they responded with a same day site visit to my home followed by a quote within 24hrs. Great service and communications. They DO service Charleston, and quite well I might add! I would especially like to thank the work crew!(Corey,Josh,Logan and Rick) They were on-time, dealt with unexpected adversity in a timely and professional manner, and completed the job order quicker than expected! A great team team comprised of both young and veteran service persons! Truly refreshing to see the multigenerational collaboration and mutual respect shown for one another by each team member! Teamwork makes dreams work! I will not hesitate to contact 304 again for any HVAC or plumbing needs in the future. Thank you 304 for helping us get settled into our new home! CM

Our AC had been having issues for a while without a fix. Roy came over this morning and was able to find the problem within 10 minutes. Roy was very knowledgeable and did a great job on explaining the issue and resolving it. Highly satisfied with this service.

We had A/C issues at first then ended up with furnace issues. 304 was able to be there in a timely manner and fix the issues. We ended up needing a whole new unit all together. Our water heater also needed replaced and everything was taken care of. Our tech was great. They are friendly & professional.

I had a main water line leak on my side of the meter. The workers were respectful and professional. I appreciated talking to a real person when seeking the service. Amber was nice and helpful. I recommend this company.
