"Iâ m a first time client and Steve was amazing to deal with. Not only did he come out first thing Sunday morning for an emergency call but he had the parts and repair completed incredibly fast. He offered several options including giving me the part info in case I wanted to save some money and do it myself since Iâ m somewhat handy. There was never any pressure and Steve communicated with me through each step. I didnâ t have a â furnace guyâ before but I do now."

"The moment we met Jay, from J and T Heating and Cooling company for an estimate for a new Central Air/Central Heat unit, we knew we were in good hands. Jay explained in detailed his vision and made sure we were updated on a daily basis of their progress. The crew was professional and very efficient in making sure everything was done in a timely manner and properly installed. They surpass our expectations in the work they did. They did an amazing job of making everything looked neat like nothing was installed. Our home is cool and like new. I highly recommend this company for any heating or cooling installations."

"Great experience Justin, Nate & Timothy were awesome. Very knowledgeable, professional & curious. Aside from the cleanliness they delivered an experience. I highly recommend HL bowman if you want rapid service on your HVAC. Pricing was reasonable in my opinion & financing is an option. Keep in mind when seeking quotes for your HVAC repair/ new install you must consider performance over equipment, that is if your want a good system that will have a good run/life span."

Air Conditioning questions, answered by experts

Air filters with a high MERV rating, 11 or above, shouldn't cause airflow problems in most residential systems. However, the airflow can be restricted in some HVAC systems if they aren't designed for high MERV ratings. If in doubt, a local duct installer should inspect your ductwork so that you know what your system can handle.

Condensation forms when warmer, outside air combines with cooler air in your ductwork. This can happen when there are leaks in your air ducts, your HVAC system has a dirty air filter, or there’s a lack of insulation around the ducts. To prevent it from happening, replace your HVAC filters as directed. Also, once every five years, hire a local air duct cleaner to clean and inspect them.

Yes, a dirty air filter can cause a higher electric bill. That’s because clogged filters make it harder for air to flow through your HVAC system, which forces it to work harder and use more energy. According to the U.S. Department of Energy, replacing dirty filters can save you between 5% and 15% in utility costs.

If refrigerant levels are low, it can cause the evaporator coil to freeze up. Low freon causes a drop in pressure, which will make the coil too cold and cause moisture to freeze on the coil. Your system may be low on refrigerant because of a leak. 

Make sure to have maintenance performed twice a year, and contact your local HVAC technician if you suspect your system has low freon levels.

While it is possible to add Freon to your AC unit yourself, it is not recommended. In fact, the U.S. Environmental Protection Agency (EPA) prohibits the handling of Freon without a license. Freon is a dangerous gas that can cause irreversible damage to your AC or yourself if not installed correctly. It is worthwhile to hire a professional to add Freon to your AC.
