Meeting Your Germantown Commercial Heating and Cooling Service Needs
Commercial facilities pose special heating and cooling challenges because the spaces are so diverse. Businesses may have office space combined with large warehouses, or rooms full of computers and other equipment that generate heat. It’s vital that each area be cooled and heated properly to ensure the comfort of your employees, while protecting your valuable equipment or inventory investments. Rely on Gross Heating for all of your commercial needs. We offer services on systems including rooftop heating/cooling units, industrial unit heaters, infrared heater systems, and more.
In addition to our services, we also offer commercial maintenance agreements and equipment leasing programs. These ensure your systems receive regular maintenance and perform properly. We can even address zoning issues where specific parts of your building are not receiving as much heating or cooling as they should.
Keep Your Germantown Home Toasty Warm With Regular Furnace Maintenance
One of the most important things you can do for your home heating system—whether it’s a boiler or a furnace—is to have it cleaned regularly. Not only does furnace maintenance keep the system functioning at optimal efficiency, it can also reduce the chance for breakdowns by up to one-third. We even offer maintenance agreements so you get the right service at the right intervals.
If you’re in need of a new HVAC system, let us handle your furnace installation. Our NATE-certified technicians are experienced in selecting units and can ensure your home will be operating efficiently in no time. That includes any furnace repair you may need down the line. We can also recommend alternative heating options such as radiant in-floor heating. You’re in good hands at Gross Heating.
Improving Indoor Air Quality in Your Germantown Home With Humidifiers and Air Purifiers
When it comes to your Germantown home’s indoor air quality, we want you to be assured you’re breathing in safe, purified air. That’s why we perform indoor air quality tests so we can address any issues that may be present in your home. Performing an air test enables us to see volatile organic compound (VOC) levels, humidity levels, and more—all of which can be troublesome if left untreated.
Installing products such as humidifiers, dehumidifiers, ultraviolet lights, and air cleaners, will help regulate these levels, and clean and balance your air. Should we find traces of radon during our radon mitigation test, we will properly ventilate it to ensure the dangerous gas is vented outside and away from your home. When you get help from our team at Gross Heating, you can always rest easy knowing we take care of everything.
Keeping Your Germantown Home Cool With Our Air Conditioner Installation
Having a working air conditioner on hot summer days is essential in order to keep your family comfortable. Call our team for expert air conditioner installation, or to maintain your current AC or heat pump to make sure it’s operating safely and efficiently. Our technicians will come by annually to inspect your system thoroughly, allowing them to catch minor problems before your system breaks down and requires a repair.
Our techs can also recommend systems such as heat pumps or ductless mini split systems if your home is in need of a newer system or extra boost. Plus, they know how to analyze your existing system and can recommend tips and tricks that will improve your efficiency and result in money savings.
