"Really fast and professional service when our HVAC broke in the peak of summer. Had it up and running in almost no time. My advice to first time homeowners like me in these cases is to always make sure you know what repairs and actions are being done. It'll help in regards to money."

"Ductz of the Upper Bay Region cleaned my ductwork today. The team was professional and friendly. The cost was stated in advance as a firm price and not an estimate. They took before and after pictures which I found very helpful. The owner and his team went above and beyond to suggest ways that I can best maintain my A/C system to minimize the need for cleanings in the future. I recommend them highly."

"I recently had a HVAC and water heater installation by Carroll Mechanical, Cris Lopez and his team. They were very respectful of my home and professional throughout the install. I am grateful and appreciative of working with the owner on deciding the HVAC unit to be installed. I found him to be the consummate professional, a person of integrity, transparent, responsive to my questions and willing to work with me to gain my business. I highly recommend Carroll Mechanical."

"Victory HVAC installed 2 mini splits for me. Great communication, they showed up when they said they would, the job was completed in one day. They worked with me regarding placement as well as advice what brand to buy. Excellent service, reasonable price, they cleaned up when done and were very easy to work with. Yossi is extremely knowledgeable about all things HVAC. Super nice guy to boot. I will definitely use Victory HVAC for all my HVAC needs in the future. 5+ stars"

"I used Regal Duct Cleaning today. Our home is 60+ years old. We have only lived in it for 20 months and there was more dust, dirt and webs than I had ever imagined. Julius and his crew arrived at the scheduled time. He was extremely professional. We went from room to room looking at every every vent, cold air return. His crew worked for five hours, cleaning the ducks, dryer vent and installed a UV light. I highly recommend Regal Duct Cleaning . I will definitely use them again! To see the before and after pictures was a real eye opener. Great Job!"

"Technician showed the mold in the ducts and explained the process for treating the mold. When the work was completed, he then reviewed the process, showed the work that was done and explained how to change the UV lamp."

Heating and Air Conditioning questions, answered by experts

HVAC pros recommend that you replace your AC filter every one to three months to maintain optimal indoor air quality and ensure your HVAC system operates efficiently. However, factors such as filter type, household size, and environmental conditions may influence the frequency of replacement. Regular filter changes help prevent debris buildup, maintain airflow, and prolong the life span of your air conditioning unit.

The standard HVAC warranty is around five years. Still, many brands offer an extension to 10 years if you register the product within a specific timeframe, typically 60 to 90 days post-purchase or HVAC installation. Over the past decade, warranty periods have substantially increased, shifting from 3-5 years in the 90s to the now-prevalent 10+ year warranties. Both warranty types cover parts failing due to manufacturer defects, incurring no additional costs. Some manufacturers provide extended warranties surpassing the usual 15- to 20-year window, though these often involve extra fees. 

A dual evaporator coil is a specific design that allows the AC system to cool different compartments at different levels. It’s usually seen in refrigerators and similar appliances, but not in whole-house air conditioning systems. Talk with your AC technician about the best uses for a dual evaporator coil.

It all depends on the unit’s SEER (seasonal energy efficiency ratio). A higher SEER rating means better efficiency and lower costs for your energy bills. 

Take a look at the product you’re considering purchasing and compare it to other models to decide which one is affordable upfront but will keep your energy costs low over time.

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.
