"It went fantastic! They showed up on time, got to work, were personable and happy to throw in a free furnace cleaning as the project wasn’t as complex as they assumed. They even had time to do a quick chimney cleaning. We couldn’t be more pleased. And the air quality in our condo is noticeably better. We had been given the runaround over and over by other companies and hed to threaten to sue one in small claims before they did the right thing and issued a refund. Don’t take a chance on wasting your time with unrated businesses. I will only go through Angie’s List from now on. They also replaced a metal piece to replace the tape the other company left after removing their magical UV cleaning light fixture. They had promised to come back and replace it with a plate, and never showed up. Bottom line, these guys are professionals and are independent thinkers who can flexibly work to accommodate the situation at hand!♥️♥️♥️"

"Riley was the technician who serviced my air conditioner yesterday. Riley always kept me informed on the progress of the work he was doing and before leaving THOROUGHLY explained the condition of my air conditioner and what I can do to extend its life. Fortunately my air conditioner, even though it’s 11 years old, is in great condition and I plan on doing things to prolong its life. Overall I would give Riley a rating of 10. He is an exceptional technician, knows his job, explains things well, and personable. The cost today was $17 for a replacement filter."

"My God! Dan came out this morning, I explained what was done, he went to work on it right away! My furnace stopped working December 25th, 2024, no heat till today! Keep in mind, the last technician I hired in January 2025, charged me 240 dollars for 20 minutes analysis just to tell me I need new furnace and AC central, my AC works beautifully. Then I used 4 space heaters to keep my house warm! Man my electric bill was over 400 dollars the first month and climbing higher each coming months till Spring arrived! I hired B & D Plumbing and Heater Co. to come out and finish the job. It was a gentleman name Dan, he did an extremely awesome job, telling me the details, explaining everything I needed to knowledge. And now the furnace works about as good as it gets beautifully. The impressive part, he took his sweet time. And the most impressive part was when he presented my total bill! I was about to have a major heart attack when I saw the bill! It wasn’t through the roof bill! Cheap cheap"

"Kody did a fantastic job. His communication skills,expertise, knowledge of his products, timeliness, job site tidiness and fair pricing were greatly appreciated. He installed a Goodman heat pump system ( heating & air conditioning), Mitsubishi multi zone mini split ( wall unit & recessed ceiling unit), an Aprilaire whole home humidifier, a UV air purification system and surge protection system for whole HVAC system. I highly recommend his services."

Air Conditioning questions, answered by experts

Replacing both an AC and a furnace takes a full day on average, ranging from eight to 12 hours. The process involves removing the old units, installing the new ones, and ensuring all connections are properly made. If both systems are being replaced simultaneously, it can take longer than installing a furnace alone, so plan accordingly.

Most units are designed only to cool the house down to 20 degrees less than the temperature outside. This means that if it’s 99 degrees Fahrenheit out and you’re trying to cool your home down to 65 degrees, you’ll notice your AC is struggling. 

Lower the blinds on all your windows, turn on your ceiling fans, and keep the thermostat at a consistent temperature to help your AC do its job. Investing in an HVAC maintenance plan also helps because pros will come out to inspect and tune up your unit regularly, keeping it in optimal working condition.

No. Evaporator coils are designed to work with specific refrigerant types, and they are rated by what kinds of refrigerant they use. It’s indicated with an “R” code. It’s important to match your evaporator coil and refrigerant or your system will not work properly. An AC technician can tell you what type of refrigerant your system needs and what evaporator coils will work with it.

Most HVAC companies recommend against setting your AC below 70 as it could freeze up the system and cause more problems. Regardless of how hot it is outside, there is generally a 20 degree difference between the outside and inside temperatures, so even if it’s 100 degrees outside, your AC will likely not be able to cool your home to 70 degrees.

Yes. Getting a whole-house dehumidifier can help you save money on energy bills. How? Your home automatically feels cooler when there’s less humidity in the air (“It’s the humidity that gets ya!” is such a true statement). This means that you won’t need to run your AC as much as you would if you had all that extra humidity in your home.
