"My furnace went out and cuddly I found myself getting bids for a replacement. I don’t make large purchases without a ton of analysis to ensure the right solution for the best price. I didn’t just have a broken furnace I have air flow issues too as the rooms furthest away never get enough air. I didn’t want to just replace I wanted to solve a 23-year-old problem. Rob was out the same day walking me through options and not over selling just giving me the facts and not pushy. His approach to resolving the air flow made sense and was very conservative as he proposed small low cost/no cost changes we could implement over time after a period of observation with the new system instead of hitting me up front with new dampers etc. up and making significant changes to the air flow. Rob clearly knew what he was talking about and has likely installed himself over the years as many systems as he has sold. There were three other comparable bids and none of them were even close to the value I was to receive from Quality West. These guys don’t look at each install as just another job they take pride in their work, are extremely professional and even have some fun along the way. They were creative in their piping as I upgraded to a two-stage variable speed system that required PVC piping so the ascetics of the piping in and outside of the home mattered to me and they were conscious of that. I would much rather work with a company like these guys that are dependent on referrals instead of doing a bunch of advertising because for them customer satisfaction really matters. This is the reason for this long review as they deserve the recognition and I would highly recommend Rob and his team Bob and Dave."

"Our residential AC is in a converted bus. We are new to the area, and first called several other companies who could not work on it (because they were RV repair technicians and not HVAC certified) or would not work on it (because most HVAC certified technicians were not work on motorhomes). We are so grateful that Pacific air was willing and able to work on our unit. We are fully satisfied with the work they did, as well as the very reasonable fee they charged."

"It was very easy to work with D&D Air Duct Pros. They were very responsive and made scheduling easy. They showed up on time, were very friendly, and did a great job. They provided before and after pics of our ducts and went above and beyond to make sure they were as clean as possible! I would definitely recommend this pro."

Air Conditioning FAQs, answered by experts

There are a few ways to reduce your electricity bills if you use window AC units to keep cool. Set the unit temperature at least 1 degree higher than it is currently to reduce costs. Keep the unit clean for it to run efficiently. You may want to hire a window AC specialist near you to inspect the unit once a year and keep it in tip-top shape.

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.

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.

Most HVAC service calls include diagnostic fees, which could include checking on a specific issue you’re experiencing or running through a routine inspection checklist. If you called for a particular problem, the service call will also include an estimate to fix the issue, including materials and labor. Depending on your HVAC technician and the service you requested, you might also get a general inspection of your system components to ensure everything is working as intended.

If you’re trying to buy a new AC unit, there are a few crucial factors to consider. Look at the cooling capacity, the available warranty, the energy efficiency, and the type of unit. A ductless unit will cost more up front but may be a more viable option if you don’t already have ductwork. Additionally, a unit with better energy efficiency will cost less to run overall, saving you money on your monthly energy bill.
