"The day of moving into my home, the AC stopped working. These guys were able to come and fix it quickly. I wish I had a service contract because I would have saved alot of money. Overall, I'm happy with the prompt service."

"JP Works responded immediately to our request for an estimate. Dave did the preliminary inspection and estimate. Very knowledgeable and professional. Jim did a second inspection of our house and provided additional information about the work to be done. Jim and Victor did the installation of a new oil-burning furnace and central air-conditioning unit, as well as removing and disposing the old furnace and duct work. It was a professional job from start to finish. We were amazed at the amount of work that needed to be done, but Jim and Victor made it seem effortless. We are so grateful to finally have the central air-conditioning, just in time for the recent heat wave! We hired JP Works based on numerous positive online reviews and we were not disappointed. We highly recommend them!"

"Came out for emergency air conditioning service. Had to shut down air conditioning for a night to thaw out the ice that formed around the unit. We had to put up window units though because it was way too hot in the house to sleep. Originally, we were told we might need to replace our entire unit. After I called back stating our current unit was still under warranty, they came back the next day, and remarkably all we needed was a freon top off. Total cost for the 1/2 cup of Freon and initial visit = $300. I will not be using them again."

"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."

"

we had a leak problem and the tech came and looked over our equipment, fixed the problem and left. It cost us nothing and we have had their home heating service contracts for over 20 years.  They have NEVER ONCE not shown up or not helped and in the two furnace emergencies we had--they were here with in 1hr. 

We are very happy.

"Our 17 year old central air conditioning went out at the start of a heat wave. I called Arctic Fire on a Sunday morning. Alex returned my call that afternoon and came out the next day around noon and quickly diagnosed the problem and had our old unit running in about half an hour. In conversation with Alex I discussed the possibility of replacing my 17 year old unit which had been a problem with 3 previous service calls in the last year. Within a day he sent me an estimate which was very competitive and reasonable. Within 2 weeks he replaced both my compressor and air handler in a very hot attic. His team was very professional and completed the job in about 5 hours. Even in very hot weather his team remained focused and answered all my questions and concerns. He did not leave until everything was running and operating correctly. I would highly recommend Alex and Arctic Fire for any of your HVAC needs."

Air Conditioning questions, answered by experts

The average life span of an HVAC system is 15 to 20 years. Even if your old air conditioner is still functional, it isn't as energy-efficient as a newer system (especially one with an Energy Star designation). Older HVAC systems aren't as efficient, and the 10-year mark is when you should start making full system replacement plans. Twenty years in, that plan should be well underway rather than waiting for the unit to die.

Aside from needing HVAC repair, there are times when you may need to replace your unit. HVAC replacement costs $5,000 to $12,500. Here are some telltale signs that your HVAC unit is going bad:

  • Your unit is 10 years or older.

  • Your home is very humid.

  • The unit keeps cycling without producing cool air.

  • You need to repair the unit frequently.

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.

Yes, technicians check refrigerant levels, loop performance, and system calibration for peak efficiency.

While Freon is mostly odorless, a Freon leak will produce a faint chloroform-like smell. Some people find that Freon's odor has a subtle sweetness to it. Some telltale signs of a Freon leak beyond odor include ice crystals on your evaporator coil, bubbling sounds, and hissing noises.
