"Dave came Monday evaluated my system for repair. I ask for information to replace instead because of a prescient leak and possible over stressed system. Jerry came Tuesday. I decided to place with a 2 1/2 ton unit 3 ton to better fit home needs. I had an air cleaning unit added. I also had mini split unit installed in garage. The four man crew came Wednesday installed very thing plus cleaned the ductwork. I am very pleased. The compressor unit much quieter than the old, hardly hear it. By the way this is all done with the Coronavirus social distance thing. Very one did extremely well."

"I submitted my request for my air conditioning problem in mid morning and he called and said he would be here around 4:00 then he called and said he would be here at 3:00. I had cool air by 4:00, He also did a few little things for me like putting up my new smoke alarm. I highly recommend Jason Brubaker."

"They were prompt and very professional. They kept us informed during the entire process of cleaning our ducts and dryer vent. They also installed an air scrubber and the total cost was several hundred dollars less than the quote we received from an HVAC company. The HVAC company told us we needed mold remediationâ ¦. DuctGurus found no mold. We received great service so we will be using and recommending this company in the future."

"We couldn’t leave a higher review for Prime Home! They are exceptionally kind, efficient, knowledgeable people who do honest & solid work. They have done so much for us this year, all at a reasonable cost & in a quick timeframe. This summer our AC broke and they came out & replaced it within days, while other HVAC companies couldn’t come out for weeks, and at a higher cost. All of their employees are courteous & respectful while performing their job and are never in a rush to get their job done. We are super impressed by their communication, care in their craft, and exceptional hospitality as a business. We will always use Prime Home for all of our HVAC needs!"

"Provided excellent and on time service. Had my gas valve replaced, knew exactly what he was doing with no hesitation. The price he charged was fair, and exactly what was quoted. Requested he come back in spring to service my ac unit. Thank You Matt. Eric K."

"I hired NS JOHNSON to install a Climate Master Tranquility 30 geothermal heating and air conditioning system. Their work was very professionally done, and spot on the budget. The installation took a day an a half. The outdoor temperature was in the low 30 degree (f). On completion of the first day they activated the system to assure we had heat for the night. They completed the installation the next day. Iâ  m very impressed with their work and would recommend them to anyone needing this service. They will continue to maintain the system on a yearly basis. I plan on using them for other services."

"Will Stahl from Stahl Mechanical called me the same day that I submitted my request for a pro. He came to my home for an estimate a few days later. He was knowledgeable about AC and electric, educating my husband and I regarding the different systems available, cost and efficiency. He and his 2 guys arrived the following week on time and finished the job in less time than estimated. Will was skillful, clean, respectful and friendly. He was genuinely concerned with the quality of his work and assisted us in setting the smart thermostat and returned upon request at no extra charge to adjust the vents to balance the air flow in all the upstairs bedrooms. I would highly recommend him to others and have given his card out to friends and family already."

Air Conditioning FAQs, answered by experts

You can buy R-22 refrigerant for your home air-conditioning system through your local AC repair specialist, who can also refill your R-22 system as needed. You may find that the cost of R-22 has gone up due to shortages as the EPA banned this refrigerant. Ask your pro to inspect your system for any leaks or issues.

If your AC unit isn’t cooling and you haven’t figured out why, there are a few good reasons to turn it off ASAP. The source of the issue, whether that be leaking refrigerant or a broken compressor, will worsen and cause more damage to the overall unit the longer the machine is allowed to run. When in doubt, shut it down until you or an AC pro can ensure everything is working properly.

Choosing between a ductless mini-split and central AC depends on your specific needs. Ductless mini-splits are ideal for targeted cooling, providing zoned comfort and energy efficiency. They are perfect for smaller spaces or homes lacking ductwork. In contrast, central AC offers consistent cooling throughout the entire house but requires ductwork and may be less energy-efficient for smaller spaces. 

Consider factors like budget, home size, and cooling preferences to make the right choice. Combining both systems, with a ductless mini-split in specific areas, can also be a viable solution for tailored comfort and overall efficiency.

Yes, adding central air can increase your home value by as much as 10%. Generally speaking, prospective buyers prefer a central AC system over a ductless system or room-by-room AC units. That’s because central air conditioning blends into the home easier than individual room air conditioners and typically has less equipment to maintain.

For the most part, you should leave your AC fan in “auto” mode so that it only runs during a heating or cooling cycle. Keeping it in this position uses less energy, which equals lower utility bills. However, there are some situations where it’s better to leave your AC fan on, including if you have allergies or there are lots of people in your home.
