"Perfectly. Best price by a small amount, but their professionalism, honesty, and clarity of explanation was best among the 5 Angie's List certified vendors that I had come out to give a quote. Very pleased with my choice. My experience with a smaller family-owned and operated business in the HVAC world has been consistently better than the bigger companies."

"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.

Owner David Kallander came to my home and gave me an estimate for a new gas furnace.  I had previously received estimates from 3 other companies.  David was professional and knowledgeable.  He sells Trane equipment, which I consider one of the best.  His price for the type of furnace I wanted was very competitive.  He also offered a way to finance the furnace through Wells Fargo for 12 months at zero interest.  No one else had done that.  The company also offers a great maintenance plan.

The men who installed the furnace were professional and worked quickly.  All of my questions were answered.  I am very happy with the furnace and the service.

"Took about 2.5 days to remove an antiquated panel, meter and mast and replace with a more modern one. They also cleaned up a bunch of wiring issues in the house and ran conduit and power for an HVAC system. I am still pending power company inspection, but I'm sure the work will pass easily."

"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."

Heating and Air Conditioning FAQs, answered by experts

After a while, dust, dirt, and other debris accumulates on an AC unit's coils and filters, making it less efficient and spreading allergens and other air pollutants throughout your home. Cleaning your AC unit will keep it running efficiently, minimizing future breakdowns and improving your indoor air quality.

You can buy a house with a 15-year-old HVAC system if you inspect the system for performance and budget for a replacement within the next three years. You can also negotiate the price with the sellers. Ask to look at the unit’s maintenance records and energy bills for the last two years to determine the shape of the HVAC system and its operating costs. Spend time in each room of the house to gauge if the HVAC keeps the home at a consistent temperature throughout.

Mold in your air conditioner isn't a good thing, as it can be harmful to your health. If the mold travels through the ductwork or is blown out of the A/C, you and your family can inhale mold spores and develop respiratory illnesses and other problems. Preventing mold from growing in the air conditioner will help protect your health.

An AC drip pan may stop draining if there’s a clog where the drip pan connects to the drain line. Clogs can form from a lack of cleaning or from rust or corrosion buildup. Cleaning the drip pan at least once per month lowers the chances of debris clogging the drain line.

Air filters with a high MERV rating, 11 or above, shouldn't cause airflow problems in most residential systems. However, the airflow can be restricted in some HVAC systems if they aren't designed for high MERV ratings. If in doubt, a local duct installer should inspect your ductwork so that you know what your system can handle.
