"Glenn Julian, the owners son, arrived within the expected time window. He allowed me to watch as he explained the various tests of the air conditioning that he was doing and he also described some of the previous experiences he has had with air conditioning systems. He seemed very knowledgeable and experienced. He finished the air conditioning maintenance check within one hour. We plan to call Julian's Heat & AC again in the fall when we need to have the heating system maintenance check done. Thank you Julian's Heat and AC for a great job done!"

"I recently had my AC installation done and I couldn?t be happier with the service! The team arrived on time, worked efficiently, and made sure everything was installed perfectly. They explained how the system works and answered all my questions patiently. The new unit is running smoothly and cooling my home perfectly. Highly recommend them for anyone needing professional and reliable AC installation!"

"My AC was not working at all and I called Romano's Heating & Air Conditioning late afternoon to get an evaluation. Mr. Juliano Galanti responded immediately and setup an appointment the very next day. Mr. Galanti showed up on time. He was very knowledgeable, friendly and professional. Price is very reasonable and he explained everything that he was doing and why, and he did not have any problem answering any of my questions. He was able to identify the source of the problem and fix it right on the spot. Romano’s Heating & Air Conditioning is an exceptional company that provides professional services and I highly recommend them."

"I met Jesse (owner) at the Auburn home. After setting an appt., he showed up on time as promised (can t say that for a lot of other companies). We reviewed what I wanted done which I appreciated because I ve had others suggest what they wanted done instead. He physically went up into my attic to access my old and inefficient insulation, including video recording it. He also spent time looking at my old windows (1980 s style) that I was also looking to replace. Jesse came up with the cost which was thousands of dollars cheaper then the several other estimates I have received. After agreeing on moving forward, Jesse played an active part in the entire project. He even provided me with his cellular number and always got back to me when any questions arose. The workers who came to install the insulation were very friendly and professional (I continuously talked to them, probably annoyingly). They took their time to assure that everything was done as promised and I even double checked their work. The next part of the project included a new slider and several windows. Jesse was on scene throughout the window installation and the final product was fabulous. Craftsmanship was impeccable and the windows and slider look great. Even after the project was complete, Jesse has contacted me to assure full satisfaction was met. I would recommend Clear Efficiency to anyone."

Air Conditioning questions, answered by experts

You should clean your air conditioner at least once per year, but you may need to clean your whole HVAC system (including the air ducts) more often. According to the National Air Duct Cleaners Association, you may need to clean them more frequently depending on factors like whether you smoke, have pets, or have allergies.

Yes, a dirty air filter can cause a higher electric bill. That’s because clogged filters make it harder for air to flow through your HVAC system, which forces it to work harder and use more energy. According to the U.S. Department of Energy, replacing dirty filters can save you between 5% and 15% in utility costs.

No, it's not advisable to only replace the outside AC unit connected to your system. AC units are designed to work as a cohesive system, and older units work differently than newer units. Therefore, replacing only one component can lead to incompatibilities that affect the system’s performance. Replacing one component can void your warranty, costing you money for repairs.

Deciding whether to replace just the AC coil or the entire system depends on the age of your unit and the overall cost. Replacing a coil is less expensive than a full system replacement, but it can still be a pricey repair. If your HVAC system is relatively new and still under warranty, or if the replacement cost is significantly lower than a new system, replacing the coil can be a worthwhile investment that restores efficiency and extends the unit's life. However, for older systems (nearing the end of their 10-15 year lifespan) or those with extensive damage, it is often more cost-effective to replace the entire AC unit. Mismatched coils in an older system can lead to inefficiency and future breakdowns, so a full replacement ensures optimal performance and avoids further costly repairs.

If you’re shopping around for a rooftop AC unit, you may hear them referred to as “package units.” That’s because rooftop AC systems are all-in-one heating and cooling units that connect directly to your home’s ductwork. If your AC repair pro references a package unit, they are referring to the system on your roof.
