"Technician arrived on schedule and was very polite and professional. Showed him a problem we were having and he immediately identified the cause and recommended corrective action and performed that corrective action while he was here. It's been two months since service was performed, and have not had a recurrence of air duct problem. Hope to have Breath of Fresh Aire conduct our regular semi-annual preventive maintenance on HVAC unit."

"Our A/C unit needed to be replaced as the original equipment was pieced together by another contractor.  They came out during the holiday season went through the entire system to see if we could repair anything.  We asked for a full estimate on a replacement and they took the time to explain what system we were getting.  We contracted with them for replacement, again during the holiday season, and the installers were timely, professional and took the time to walk us through what was done.
We are impressed with the work and they will have our business going forward.

"Our AC was running however the fan wasn't turning. Pat came to our house at 8:30pm and started working on the unit--had it fixed within 20 minutes!
Fontana Brothers is the only company I trust for heating/air related issues. I've delt with so many companies and find that most of them want to charge an arm and a leg, then try selling you something on top of it. Fontana Brothers have always been professional, timely and trustworthy--prices are great too!

"This was an excellent experience from beginning to end. Kyle H. came out and evaluated the room I needed hvac in and provided a very fair estimate on site. Scheduling for installation was within just a couple of days. Dennis and the install crew were fantastic. The installation is very neat and tidy and they cleaned up after themselves. The Mitsubishi floor mount unit and the app work perfectly. I truly couldn't be happier! 5 stars should be 10 for excellence!"

"ABC's HVAC installation lead, Jonathan D., and his associate did an exceptional job replacing my 21-year-old HVAC system. As a former aerospace engineer, I know technical talent when I see it. Despite the job being more complex and requiring longer hours than anticipated, they prioritize "quality first" to ensure a successful outcome. This is the second HVAC unit that ABC replaced for me, and I highly recommend them!"

Heating and Air Conditioning FAQs, answered by experts

Vents may blow air even though the air conditioning system is off because of the pressure difference between indoor and outdoor air or drafts from leaky ducts. Check for leaks or drafts in the ductwork or around windows and doors.

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.

Yes, scorpions can enter a home through AC vents, especially if the system is not well-sealed. As excellent climbers, they can scale a home's exterior and squeeze through gaps as small as 1/16 of an inch. Scorpions are often attracted to the moisture around air conditioning ducts or seek cooler areas during hot weather, using vents as a pathway inside. They may slip through small openings where the duct meets the vent cover and travel within walls before emerging. To prevent this, inspect your vents, seal any gaps, and consider installing fine mesh screens.

At a minimum, an HVAC system should be serviced once per year. However, a twice-a-year service schedule—once in the spring for the cooling system and once in the fall for the heating system—is often recommended, especially for older systems, heat pumps, or in climates with extreme temperatures. Regular service, which includes inspection, cleaning, and maintenance, ensures the system runs efficiently, helps prevent costly breakdowns during peak seasons, and can extend the unit's lifespan. You can also schedule a service if you notice issues like poor performance or strange noises.

To keep a window air conditioner in good working order, you should clean the filter regularly, inspect the seals, and store the unit properly during the off-season.
