"I conducted a lot of research prior to hiring Air Factor, and obtained bids from 6 different contractors. Air Factor was the ONLY company to calculate the size of my home to determine the appropriate size of the AC unit to properly cool my home. They were VERY thorough on the initial visit - spending 2 hours with me. Tim had a great presentation put together, including reviews from customers, insurance information, and BBB ratings/reviews (ZERO complaints by the way). The detailed information he provided built trust in the contractor. I would use them again in a heartbeat, and will definitely recommend them to my friends and family."

"I am a homeowner who is out of state. Gerardo was extremely proactive and responsive when I called him. Within two hours he had done an assessment and provided me a quote that was 15% lower than the next best quote (I had received from another company). Within a day his team had installed the hvac system and had it operational. I highly recommend Sun Devil heating and cooling."

"After a sleepless night (too hot) with little AC, I put in a request for AC service with Angi. Within seconds of completing my request, one hour Heating and Air Conditioning reached out. I scheduled service for a few hours later that same day. Cody came out and worked on the system for around two hours to resolve our issue. He stayed long enough to insure the system was working as it should. Upon completion I was expecting a fairly large bill for the service but was delighted to find I could sign up for regular service for a small fee. Everything is working great and we are happy and Cool!"

"By the time of this review the AC had been down for a week with interior temps almost reaching 100 degrees. During that time we already contacted two other HVAC companies to diagnosis & repair quotes. Both claimed that the Blower wheel & motor needed to be replaced. The quotes received for the parts/labor were really high. We told them our finances were tight & we just wanted to repair the current HVAC system but both repeatedly tried to convince(upsell) us to buy or finance new HVAC units instead of repairing. So we kept looking & we submitted our repair project request on HomeAdvisor. Just minutes later we got a call from Annette at Sinclair Air LLC. She was very courteous & understanding of our financial situation. She said that her husband Troy was on already on a service call nearby & would come by afterwards to take a look. About 30 minutes later Annette called back to let us know Troy had finished up early & was on the way. He arrived just a few minutes later & immediately got to work. A short while later he came down with the Blower motor & wheel assembly unit. He then walked me through what had likely happened & explained that neither the wheel or motor needed replacing but had found a bad capacitor that did need be replaced. He told us he would be able to repair the Blower, replace the bad capacitor & reinstall everything for an extremely reasonable price compared to the previous quotes we had received. We immediately agreed to have him do the repairs which he then proceeded to do then about an hour or so later the AC was pumping out cold air again. Troy even stayed around after the repairs were completed to make sure everything was cooling properly and gave some tips on how to improve cooling down the house. Troy & Annette are both professional, friendly & caring people. Troy is very knowledgeable making sure to explain what he finds in his diagnosis & what he can do to resolve the problem. We are VERY SATISFIED with the excellent & quick service we received from Troy & Annette at Sinclair Air LLC. They helped us out in our time of need & we DEFINITELY RECOMMEND them for anyone looking for quality HVAC work at a reasonable price. We are keeping their number on speed-dial for any of our future HVAC service needs. Thank you Troy & Annette we really appreciate it!!!"

Heating and Air Conditioning FAQs, answered by experts

The simplest indicator is how long it’s been since your last tune-up. You should schedule an annual AC tune-up each spring. Beyond that, there are multiple signs that your AC needs a quick check by a professional. These issues include higher-than-average energy bills, decreased air flow from vents, higher indoor temperatures, and an air conditioning unit that stays on all the time or frequently turns on and off.

A new HVAC system combines components to control indoor temperature and air quality. Features include a furnace or heat pump and an air conditioner or evaporator coil, depending on the climate requirements. It also involves a network of ductwork for air distribution, a thermostat for temperature regulation, and electrical connections. Air purifiers or humidifiers can be integrated to improve indoor air quality.

Some HVAC systems tend to use R410A refrigerant, although if you have an older model it may be using R22. R22 is banned due to its harmful environmental and health impacts, and it is a sign that your AC unit is old enough to consider a replacement and the significant efficiency gains that could come with it.

While an air conditioner can temporarily run with a dirty filter, it is not recommended as it will not work efficiently. A dirty filter forces the system to work harder to circulate cool air, leading to reduced airflow, increased wear and tear, and higher energy bills. This added strain can cause the air conditioner to overheat or fail prematurely. Furthermore, a clogged filter may allow dust and dirt to accumulate in your ductwork, negatively impacting air quality. It is more cost-effective to clean or replace filters regularly than to pay higher utility bills and risk needing to replace the entire AC unit.

The cost to replace an AC unit averages around $5,900, with a typical range between $3,900 and $8,020. The final price depends on several factors, including the type and size of the air conditioner, its efficiency rating, your geographic region, and labor costs for installation. Smaller units like portable and window ACs are much less expensive, costing between $90 and $550, compared to central or ductless systems. If your current unit is less than 10 years old, repairing it may be more cost-effective than a full replacement.
