"With freezing weather on the way, it was time (past time) for maintenance service on our 10-year-old gas furnace.  After much research on the List, I called Pacific Air Systems because of their positive reviews.  The office staff were cheerful and helpful, and they worked with us to get an appointment time that would disrupt our workday as little as possible.  Technician Nathan was perfectly on time.  He was friendly and professional, everything you would want in a technician (he was even very kind to my pet).  He explained up front what the maintenance service would include.  Fortunately, no problems were encountered.  One component was at the end of its useful life, and he gave me the option of replacing it now or waiting, and he explained the ramifications.  I played it safe and replaced the part while he was here.  When done, he explained the company's optional service contracts with absolutely no pressure to buy anything.  I did decide to purchase a one-year agreement just to avoid the hassle of trying to remember to schedule next year's maintenance appointment.  It's a good idea to have reliable service providers lined up for your plumbing, electrical, and HVAC needs in advance, and I feel very confident in Pacific Air Systems after this.

"Purchased 2 smart thermostats, installed them myself and apparently blew a panel board I didn't know I had. They moved the new panel out where I could actually see it, previous tenant had hidden it behind the furnace, and repaired all of the damage I had unwittingly caused. Explained everything, kept me up to date while they were doing the repairs, and overall, I just feel very glad I went with Rob and HVAC Service Pros. The previous company I'd used, Ranger HVAC, had told me things in my system were A-OK, when they weren't. I highly recommend hiring Rob and HVAC Service Pros. Quick response, knowledgable, saved my bacon. No complaints, nothing but praise."

"Ranger did a great job. The estimators were friendly and thorough, the installers and team we encountered were all respectful and hard working. There was a problem with the electronics in the thermostat from the factory, they worked late and had to bring a new thermostat the next day, but the new one works perfectly. We will hire again for any other HVAC needs. We chose a higher quality AC unit and are glad we went with a quieter model, the unit is so quiet in the backyard."

"Received 4 quotes. Cummings was the least expensive that I used to bargain two others to. They matched but had install dates of 30 days. Cummings had their electricians and HVAC guys here in 8 days. Installation done in 4 hours. All had good customer service & tech skills."

"Ron, the owner was fantastic, punctual, friendly, and helpful! Before we moved in, we wanted to get our air ducts cleaned. Ron answered all of my questions on the phone and was very helpful in explaining the work he would do and was very straightforward with pricing. Ron charged a flat rate that also included dryer vent cleaning and a sanitizing treatment. We didn't plan on getting our dryer vents cleaned but after seeing how much gunk he pulled out, we were so grateful he did it! It probably saved us from a fire. He showed up early, worked very quickly and was gave us some really valuable tips on how to clean out our furnace and do annual maintenance to upkeep our system better. Highly recommend. Thank you!!"

Heating and Air Conditioning FAQs, answered by experts

The length of an AC cycle depends on the settings in your thermostat and the unit you have. Central AC doesn't constantly run at full blast the way that a window unit does. A cooling cycle in most homes is 15 to 20 minutes. Then, the unit stays off for seven to 10 minutes to circulate the cold air in the house before the cycle repeats. It should repeat two or three times per hour. A short cycle lasts less than 10 minutes and then turns off.

Water buildup in your HVAC system is a cause for alarm. If water accumulates in your ductwork, it can drastically lower your home's air quality and create safety hazards. These risks include mold growth, damage to your HVAC system, and attracting pests that are seeking water into your ducts. Proper insulation and sealing of ducts can prevent this, and regular inspection and maintenance can address water damage problems before they become too severe.

The higher the BTU rating an air conditioner has, the more effective it can be at cooling your space. It will cool off your room faster in the short term. However, over the long term, if the unit has too many BTUs for the space, it can wear down the unit faster and shorten its life span.

The size window AC you need depends on the BTU and the size of the room you’re cooling. For a room with 8-foot ceilings, look for about 20 BTU per square foot of the room. For example, a 12-by-12-foot room should have an air conditioner with 2,880 BTU. You can buy something slightly more powerful, but don’t overshoot the BTU for a small room, or you’ll waste energy and have higher bills.

ACs don't run on water. They're not connected to drain pipes or any part of your plumbing system. However, they need refrigerant to run. Refrigerant is a gas or liquid that has a low boiling point and absorbs the heat in your home. ACs need this in order to be functional and cool your home. If you suspect your AC is low on refrigerant, you need to contact a licensed HVAC professional. Refrigerant is a dangerous chemical that requires specialized training and permits to work with.
