"Hammer HVAC was truly concerned about our heating issue. They arrived the same day as I contacted Angi Home Advisor. Hammer HVAC diagnosed the issue and returned the next day with parts to complete the repair. Excellent customer service & extremely knowledgeable."

"We hired Bactronix to clean the HVAC ducts in our house. Technicians Masson and Shawn arrived on time, did their work unobstrusively and efficiently, and answered all my questions politely and fully. They sent over before and after pictures of the ductwork by e-mail afterwards. Their work has made a positive difference to the air quality in the house, and we appreciate their services."

"Highly recommend Kenders HVAC! Both our furnace and air conditioner broke down at the same time, which was a huge stress, but the team at Kenders handled everything flawlessly. They showed up right on time, gave us a very reasonably priced quote, and managed the entire process from beginning to end in less than a week. Their team was professional, efficient, and left everything spotless. If you want honest, high-quality, and fast service, look no further than Kenders!""

"Our air conditioner broke on labor day week-end. Called contractor late Sunday afternoon and got his answering service.  Contractor called back within the hour and set an appointment for the following morning.  Contractor called 1/2 hour before showing up on Labor Day.  He quickly diagnosed the problem and replaced the capacitor.  This capacitor has gone bad in the past and other contractors have charged $175 - $200 to replace this part during normal working  hours. I was charged the $40 advertised service call price and $75 for the repair part. In addition to repairing the unit he cleaned it. Very professional and courteous, I would highly recommend using this company. 
Most of my dealings with HVAC contractors over the past 30 years have been mostly less than pleasant, this was quite a surprise to find an honest, hard working contractor."

"Along with installing new bedroom and closet doors, the contractor also installed vinyl plank flooring in our living room, dining room, and bedrooms. He also hung our dining room chandelier, and installed moon lights above our fireplace. His attention to detail in his work was impeccable and he completes the job in a timely manner. I would recommend his services to anyone looking to have work done on their home."

Heating and Air Conditioning FAQs, answered by experts

Florida rooms can have heat or air conditioning, although not all do. These rooms can be added to the existing HVAC system or use a mini-split system, or they may just use a ceiling fan or the breeze from the windows for cooling. Florida rooms with air conditioning often have glass windows to keep the cool inside instead of just mesh screens.

You should know the main components of an air conditioner: the condenser coils, evaporator coils, drip pan, AC filter, ducts, and refrigerant. Each part plays a key role in the performance and safety of your AC system. When tracking the source of AC issues or odors, it helps to know where to look. Your outdoor unit houses your condenser coils, fan, and compressor. Your indoor unit houses your evaporator coils, drain lines, and filter, and it connects to your ductwork. 

It depends on how fast an HVAC technician can resolve the issue. First, if there's a refrigerant leak, you’ll want to keep small children and pets out of the house. Next, you’ll want to turn off the AC unit to ensure no more freon enters your home. Finally, you’ll need an AC technician pro to come to your home and fix the leak immediately. Ultimately, it’s best to leave your home if you discover a freon leak—the risk of exposure is very high, and it’s not worth risking your health to stay.

There are several steps you can take to prevent your AC drain from clogging. This includes cleaning the drain line at least every three months, changing the filter every one to three months, and getting your AC serviced annually. Also, if any problems arise with your AC, hire an HVAC technician to deal with them ASAP.

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.
