Forced Air Heating

Forced air systems present an energy-efficient alternative to central heat and air conditioning units by distributing air throughout a home or a structure through ducts and vents. More than any other heating system, a forced air system pumps warm air through your home quickly. Plus, forced air heating systems use natural gas, one of the most affordable substances as opposed to water or electricity. New technology has also allowed for these systems to provide an even greater level of efficiency for your furnace, so they can help reduce heating costs over time. Let us help you find the perfect forced air heating system for your home!

Heat Pump Repair & Replacement

Heat pumps offer an energy-efficiency and cost-effective alternative to using a furnace, especially during the winter months. Heat pumps operate by transferring heat rather than generating it. This means they are just as efficient warming or cooling your home as a traditional furnace or AC unit, all while reducing operating costs. Trust the expert technicians at Mercury Heat And Air Conditioning to install a new heat pump for your home or repair a damaged one. We ensure your heat pump is functioning at optimal efficiency, which we diagnose and measure precisely using the Heating Seasonal Performance Factor (HSPF).

Furnace Replacement & Installation

If your heating equipment is 10-15 years old and is not heating your home like it used to, it may be nearing the end of its optimal life. Even high quality heating systems will eventually lose efficiency and will need to be replaced. Our HVAC installation experts can come to your home and let you know how much time you have left with your furnace and can make recommendations to prepare for a new unit. New furnaces and heating systems are much more energy efficient than models released just a few years ago, which means your new heating unit will start saving you money on your energy bills. Contact Mercury Heat And Air Conditioning today and find out about our superior HVAC installation services.

5 Star Reviews

“Ray and Zach were very thorough in removing my old furnace, vacuuming the entire closet before putting in the new furnace. They were very careful not to track in any snow or dirt, they put down drop cloths to walk on. They made sure I understood the thermostat before they left. They completed the job in speedy time. I thank Ray and Zach again for a job well done.”

“Ray was very knowledgeable and gave a great competitive price. They only took a few hours to install my furnace. They were on time and answered all my questions. I had about 3 other quotes that were not even close. I would recommend to others for their great service!”

“Ray was an amazing professorial and showed me everything so I could make the right decision for my home. I highly recommend Ray for any homeowner. Also his amazing responsiveness was outstanding. Came on Sunday and replaced the furnace on Monday! Thanks Ray!”

Dennis N., Denver, CO

“Ray made it out on the same day I contacted them (which incidentally was a Saturday). He was very knowledgeable and professional. He was able to replace my deceased furnace first this Monday morning (which was great because another cold front was on its way). He did a great job installing the new equipment (very neat and detailed). I will recommend them to others and I intend to use them again (I have a pending AC project that I will likely do in early spring).
