"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

The cost to add Freon to an AC ranges from $100 to $350. It can increase up to $600 for large AC units requiring much more coolant. The cost also depends on how much refrigerant your unit needs. If only a small amount of Freon leaked out, your cost would be on the lower side. A complete replacement of all the required refrigerant can get expensive.

A blocked return air vent can cause your HVAC system to work much harder and, therefore, less efficiently. The result is higher utility bills and poorer air quality. A blocked return air vent can also cause unpleasant dust, dander, and odors to linger in your home’s air.

Yes, the furnace and AC use the same blower. The blower is located in the base of the furnace and pushes hot air out of the furnace and into the ducts. It also pushes cool air through the home when the air conditioning is on. Even though the furnace and air conditioning work independently of one another, the blower is an essential component for both systems.

To make the most out of your AC, consider implementing the following best practices: 

  • Choose the right size AC for your home to ensure your unit runs as efficiently as possible.

  • Choose a window with shade, as direct sunlight can cause your AC unit to overheat. 

  • Clean or replace the filter at least every two months. 

  • Inspect the AC’s fan and straighten it if necessary. 

  • Discontinue use immediately if you suspect a malfunction, as running the AC while broken can lead to significant issues. 

  • Turn off (or adjust the temperature) when you leave the house.

AC evaporator coils should be cleaned at least once per year to keep your unit in good condition. For optimal performance, consider cleaning them twice a year—once before and once after the main cooling season. More frequent cleanings may be necessary for older systems, units with performance issues, or those in climates with high levels of humidity, dust, and dirt.
