Q: Can I build a deck over my HVAC unit?

• <div><p>Yes, you can build a deck over your outdoor HVAC unit, but you need to leave at least 5 feet of vertical clearance above the unit. If you don&rsquo;t want your deck to be that high off the ground, you could <a href="https://www.angi.com/articles/how-to-build-floating-deck.htm">build a floating deck</a> in another part of your yard&mdash;again, as long as you leave at least 4 feet of horizontal space between the deck and your AC unit.</p></div>

Q: Is it worth replacing an AC coil, or should I replace the entire system?

• <div><p>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.</p></div>

Q: How do I know if my AC needs to be recharged?

• <div><p>There are ways to <a href="https://www.angi.com/articles/detecting-refrigerant-leaks.htm">detect a refrigerant leak</a> with several different testing methods. However, most homeowners can figure out something&rsquo;s wrong with their AC unit by noticing these common signs:</p><ul><li><p>Ice forming on the evaporator coil</p></li><li><p>Water leaks near the AC unit</p></li><li><p>Frequent hissing sounds</p></li><li><p>Increased electric bills</p></li><li><p>Unit takes longer than usual to cool</p></li><li><p>Unit is blowing hot air</p></li></ul><p></p></div>

Q: Do mini-splits cool as well as central air?

• <div><p>Yes, mini split systems cool equally as well as central air. While a central system circulates air throughout the entire home at the same temperature, a mini split system allows each room to be cooled or heated at different temperatures based on your own preferences. Hire a HVAC professional to determine which type of system is best for your home. </p></div>

Q: How do I know if I need a new AC condenser?

• <div><p>If your AC condenser is nearing the end of its life, it might leak fluid or make loud or unusual sounds (like grinding or hissing). You might also notice that it isn&rsquo;t heating your home as evenly or effectively as it once did. Also, an aging condenser will have to work harder to cool your home, which may force it to use more power and drive up your utility bills. </p></div>

"As a homeowner in Clovis, CA, I couldn’t be happier with the AC service repair I received from Roo’s Heating and Air Conditioning. From the moment I called, I felt like I was in good hands — they scheduled me quickly, showed up on time, and took the time to explain exactly what was wrong with my AC unit. The technician was friendly, professional, and worked efficiently to get my system up and running again, which made a huge difference in this Clovis heat! I really appreciated their honesty and fair pricing, and I wouldn’t hesitate to call them again or recommend them to friends needing air conditioning repair or HVAC services."

"We own a home-based business which relies heavily on our computers operating efficiently. We have had a service contract with another computer repair business for several years. Recently when we were having problems with our computers, we tried contacting our service contractor multiple times. He never responded. Feeling frustrated, I contacted James at North Alabama Technical Services and explained our situation. He instantly came to our rescue. He "cleaned-up" our computers and took care of all the problems we were experiencing. He went above and beyond to help us in our dire time of need. We would strongly recommend James and his company for computer service needs. We have now retained him on a service contract and are looking forward to working with him in the future."

"My friends had installed a new HVAC system and they told me that the system improved the monthly utilities bills and the house is always warm. I contacted the company that made the installation and I spoke to Ezra. Ezra provide me with some basic information about them and about the system that they installed at my friend’s house and he asked me to pass by and look at my house in order to determine what will be the best system for my house. Ezra arrived to my house and checked the existing system and he explained to me the differences between that one to the new one. I decided to hire them and to go for the system. Before the installation, Ezra came over and did a special test that took close to 4 hours. He covered all the windows and ducts and ran a special machine that supposed to check and detect any leaks of energy. The end results of the test came out good and this was a good relief. The installation of the HAVC system went smoothly and without any issues. The work took 2 days and the new system start to prove itself. I must admit that I’m happy that I was referred to this company and that I hired them for this work.
