Get matched with top air conditioning pros in Poway, CA

Q: Is it bad to run AC below 70 degrees?

• <div><p>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&rsquo;s 100 degrees outside, your AC will likely not be able to cool your home to 70 degrees. </p></div>

Q: What happens when a return vent is blocked?

• <div><p>A blocked return air vent can cause your HVAC system to work much harder and, therefore, less efficiently. The result is higher utility bills and poorer air quality. A blocked return air vent can also cause unpleasant dust, dander, and odors to linger in your home&rsquo;s air. </p></div>

Q: Is 72 a good temperature for air conditioning?

• <div><p>While 72 degrees is a comfortable setting for many people, it&rsquo;s likely not the most efficient temperature setting for your air conditioning unit. By pushing the temperature up to 75 or 78 degrees, you stand to save money on your energy bill. That said, these temperatures may be too warm to be comfortable for some people and are definitely too warm for most people to sleep comfortably.</p></div>

Q: How much does it cost to install a ductless mini-split AC system?

• <div><p>The cost to install a ductless mini-split AC system ranges from $2,000 to $14,000, depending on the type of unit, the number of zones or rooms, and the complexity of the installation. On the low end, a system for one or two zones in a single room costs around $2,000. Covering two zones for more rooms can cost between $6,000 and $8,000. For a larger multi-zone system to cover an entire home, costs can be $14,000. If you don&rsquo;t already have an AC system in place, you may need to add the cost of permits, an electrician, and a concrete pad.</p></div>

Q: How many quotes should I get for HVAC replacement?

• <div><p>You should get anywhere from three to five quotes for HVAC replacement to get an idea of the average cost of a new unit. Although this quote-collecting process can be time consuming, it allows you to compare what work is required, what type of unit you should install, and how much you should expect to pay for the service.</p></div>

"I had used Ed before with my other house. I recently hired him to clean the dryer duct at my other house. When he moved the dryer, he saw that there was a lot of lint in the body of the dryer (a fire hazard). Because he could access it, he cleaned it all out as well as the duct. The air flow is perfect. I recommend Ed and Air Duct Professionals highly. I have used his company two times, and I am extremely satisfied."

"Pat and Tom installed a 5 ton heating and AC unit in my garage/workshop, last summer, and now I can make saw dust 7/24 all week long. Their work was exceptional. Service after installation was done without question. Pat replaced a part in my electrical panel that was defective. Professionalism, installation was exactly what I needed, based upon the size of the garage/workshop area I work in. Service after installation was right on.
