"Highly recommend J.P. Works. LLC! So professional yet very friendly. They did a great job installing our new central air conditioning system. They cleaned up after themselves and told us how best care for the system. Their prices are very good for quality equipment. Great job to Jim and his crew... and the owner Dave so personalable he followed up to make sure we were satisfied. We are very happy with our new central air system. Keep up the GREAT work J.P. Works LLC. Love the Aviles family..."

"The appointment was made within 2 days of contacting them. The technician (Brian) was punctual for a 7:30 am appointment. Once there, Brian did a fantastic job of communicating the services that he was performing and kept me very informed about the status of the AC system. He found some issues that had been previously overlooked by former HVAC technicians and provided me with a very detailed understanding of what the outlook for my unit should be in the future. I noticed an immediate improvement in the cooling of the house as well as the air quality. I can't thank this company and this technician enough for being so professional in the way they conduct their business. I would recommend them to anyone in need of HVAC service."

"I met with about twelve hvac contractors as my project was a large job that included two systems and duct work. I met Erik last and he was the most straightforward person and did not try to up sell me. He painted the picture of what he would do and was confident in his proposal. When the work started it was smooth and detailed. Erik and his crew answered my many questions which helped me feel more confident. Overall a wonderful experience and value for your money. Erik included many items that other companies did not which helped the end product look and function better. Thank you!"

"I would give MORE stars if I could. Service was excellent. Greg arrived at the appointment time, was clear about what he would do and how he would do it. He was very clean in his work. He removed all duct covers, then began the cleaning. I had some issues with the antibacterial disinfectant (allergies) he would be using. He advised I could research it and let him know. He even allowed me to smell the disinfectant. We did use it and the smell was very mild and dissipated in about a half hour. After cleaning the duct work, he returned all the duct cover and cleaned up his work area. He worked by himself and had the job done in under 3 hours. And the price was fantastic, coming in at over $150.00 and $300.00 less than 2 other bids. If you're looking for duct cleaning for your HVAC system or dryer (he did that, too!), The Duct Pros are where you want to go! Thank you Duct Pros!"

"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."

Heating and Air Conditioning questions, answered by experts

If you have central air conditioning, it’s fine to run your AC all day if that’s what you want—as long as the AC unit is in good condition. But if your AC runs constantly when you don’t want it to, there may be a problem with your system (like the ones we’ve mentioned above). Window AC units and wall air conditioners aren’t as powerful as central AC, so you should only run those kinds of air conditioners for eight to 12 hours at a time.

While your AC unit may still run even if its capacitor is going bad, doing so takes a lot more energy, so it can drive up your electric bill and cause further damage to your AC unit’s parts. If you suspect a bad capacitor, it’s important to have a professional diagnose and fix the problem before you continue to run your AC.

While it's generally safe to stay in a home with a coolant leak if your home is properly ventilated, it's important to have a professional come out to assess the situation right away. You should evacuate your home if you notice any powerful fumes. Additionally, you should leave your home if you are experiencing headaches or dizziness.

No. HVAC, which stands for heating, ventilation, and air conditioning, includes all of the systems that work together to regulate a building’s temperature and humidity levels. In comparison, air conditioners only provide cooling. You can have an air conditioner as part of your HVAC system, but not all HVAC systems include air conditioners.

On average, replacing an AC compressor costs between $800 and $2,300, but it could cost as much as $2,800. There are a few factors that impact the price of a compressor replacement, including the type and size of the compressor, as well as the type of HVAC system and local labor rates.
