Radiant Floors

Have you ever been frustrated while trying to arrange furniture around your heating and cooling vents? What could you do with all that space your furnace takes up in your utility room or basement? Today, Greenfox offers an alternative to bulky, vent-dependent heating, ventilation, and air conditioning (HVAC) systems that can eliminate these issues.

Radiant floor heating is installed under the floors of your home. This electric- or water-based system provides heat through your flooring instead of blowing warm heat through your air ducts. As the heat rises, the interior of your home warms up efficiently and evenly.

Since radiant floor heating is so close to your living space, it only needs to heat up to about 84 degrees Fahrenheit to provide comfortable room temperatures. In comparison, a radiator usually reaches 150 degrees in order to warm up the surrounding air.

Radiant floor heating is a great addition, especially to new construction, in . Once installed, it is less expensive to operate, easier to maintain, and safe. It will eliminate hot or cold spots in your home and free up all that space taken up by vents and HVAC equipment.

Installing radiant floor heating can take some time, however, and disrupt daily life as the flooring will need to be lifted. Installation is usually more expensive than installation for a conventional HVAC system.

Talk with our professionals at Greenfox by calling 410-992-8200. We would be happy to answer your questions and provide more details. Request radiant floor heating service online today.

Air Conditioner Installation in Columbia, 21044

“Working with Greenfox was a huge pleasure. They were the third company we asked for estimates to replace our A/C and furnace and they came in considerably below the other two. The installers were the best we've had over our lifetimes. Bruce and Israel were everything you would want and the job was completed before we knew it. We cannot say enough about them and their company.”

Gas Furnace Repair in Columbia, MD 21046

“After a questionable misdiagnosis from another HVAC company where they claimed I needed a new Furnace Control Board ($1,350), I contacted Greenfox and Roger came out the next day was able to properly identify the problem in less than 10 minutes (a cut wire to a sensor) and when he reconnected the wire, everything worked again! So it was apparently not the Control Board, or any actual part that was bad. My thanks to Roger and Greenfox for a wonderful service experience. I would highly recommend Greenfox to anyone looking for an honest and experienced company right here in Howard County.”

Plumbing Repair in Columbia, MD, 21044

“It all started as a simple DIY job, until the stem valve under the sink broke. So glad Greenfox was able to send a plumber out- FAST for emergency repair. Ahmer and Henry were great! Knew right away how to fix the issue and prevent it from happening again. Nice guys, thorough work. Worked fast (in a really tight spot) and did a great job. Cleaned up when they were finished. Emergency solved fast and correctly!”

Heat Pump Replacement in Columbia, MD 21046

“My Heat Pump failed in the middle of the worst heat wave in recent years with temperatures soaring in the 90 degrees. When my heat pump failed and a repair was only followed by another breakdown that led to indoor temperatures up to 90 degrees, Greenfox came to rescue and intalled a new heat pump and air handler. What is remarkable is that the breakdown of my old unit occurred on a Friday before the Labor Day Weekend. Rather than wait until Tuesday of the next week to come and install the new unilt, members of the Greenfox team (Bruce, Hamon, and Henry) volunteered to come in on the weekend to perform the installation of a new Heat Pump and Air handler. I found them to not only be highly professional, but also highly trained and very knowlegable of the technical aspects of HVAC Systems. The HVAC install has run perfectly with a level of comfort my family and I have not experienced in a long time. I offer my sincerest appreciation to the technicians who performed this excellent job and I would not hesitate to have them service my HVAC System in the future.”
