"I called them based on reviews on Angie's list. They were very responsive and quickly came over to look at our older air conditioning unit that was not working. They said that while they could repair, it was better to replace it with a new one because the unit was too old and repairs could not carry warranty. We agreed. The price quoted was reasonable. Richard and a co-worker did the work. They replaced both the AC and furnace units (Trane) with TempStar. Overall, we found Cool Air team to be professional and knowledgable. We have not yet used the AC given the weather has been nice but we will in summer for sure! There is 1 year warranty on labor and 10 years on the unit."

"Quick response. I had another company come out and didn't have a clue after 2 hours. Said they were going to come back with parts ordered and never heard back from them. Gordon identified the problem within 20 minutes or so and provided a quote. Same day repair and completed in less than an hour. Gordon was knowledgeable, professional, and efficient. Price was very reasonable but it didn't matter as AC and Heating is essential when weather conditions are high and low. I'm happy to have AC again in our hottest temperatures of the summer."

"Oh My Gosh! What an amazing company to work with! I can’t stress enough what a pleasure it was having them in my home! John and Lauren worked smoothly and respectful throughout the day explaining everything to me. This is the first time I’ve had air conditioning. If I could give these gentlemen a 10 Star ⭐️ rating I would, period! You will not go wrong using their services from the price quote to a professional, thorough completed job! Thought it would take 2 days but no only one! Thank you John and Lauren ??"

"We had Temp Air install our AC unit. The best decision we ever made. They were fast, reliable and dependable. Excellent customer service, did a phenomenal job. After a couple of years something was going on with our unit, I called them and immediately they send out a technician Juan, who was phenomenal. He explained what the issue was and resolved it asap! Highly recommend this company!"

"Tyler Jones from All City Plumbing Air and Electrical did a great job replacing a gas valve in our garage. He was friendly and easy to engage with, clearly knowledgeable, and took the time to explain what he was doing. The work was completed efficiently and effectively, and everything was handled professionally from start to finish. I’d definitely recommend Tyler and All City for plumbing and gas-related work."

Air Conditioning questions, answered by experts

Running an air conditioner with mold is not safe because it can spread harmful mold spores throughout your home. Exposure to these spores can trigger various health problems, including respiratory issues, allergies, coughing, wheezing, sneezing, itchy eyes, and a sore throat. It may also aggravate asthma in household members. Continued exposure can increase the risk of more serious illnesses like sinus infections, pneumonia, and bronchitis. If you suspect mold in your air conditioner, you should stop using the system until it has been properly cleaned to avoid health risks and further contamination.

If your central AC is not blowing cold air, you should try resetting the system. Many systems have a reset button. Make sure your thermostat is off, then turn off the circuit breaker that powers your AC. Hold the reset button for three to five seconds, then turn the circuit back on. Set your thermostat to cool and choose a temperature cooler than the room. Your system should turn on quickly.

No, heat pump maintenance needs are very similar to air conditioners, including keeping outdoor units clean, changing filters regularly, and occasionally scheduling a refrigerant check to see if any has leaked out. Heat pumps typically switch automatically between heating and cooling, so you don’t need to worry about manually changing them every season. However, since they are always on call, they can develop wear and tear faster than an air conditioner.

Keeping your air filter clean is crucial for your heat pump's efficiency. As a general rule, you should check your air filter every 1 to 3 months. However, the actual frequency might vary depending on factors like the type of filter, indoor air quality, and the amount of dust and debris in your area. If you notice the filter is visibly dirty or clogged, it's a clear sign it needs attention sooner. Regular filter maintenance ensures proper airflow and helps your heat pump perform optimally, keeping your indoor air fresh and comfortable.

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.
