"Sean was great about repairing my disconnected dryer air duct having to go into the crawl space and figure out what was going on. I'm glad he was able to get it done very quickly as well. He also had a very good attitude about doing the work."

"I highly recommend Trinity A/C & Heating. Our air conditioning system stopped working, so we called another company to diagnose the problem. After a brief inspection, including a trip to the attic, they told us we needed a completely new duct system at a cost of nearly $8,000. Fortunately, we decided to get a second opinion and called Trinity A/C & Heating. Jimmy thoroughly inspected the system and quickly identified the real issue: the system was simply low on refrigerant. They fixed the problem for a little over $300, and the A/C has been working perfectly ever since. Jimmy and Mike were honest, professional, knowledgeable, and took the time to explain everything clearly. Their integrity saved us thousands of dollars and prevented us from paying for unnecessary work. It's refreshing to find a company that puts honesty and customer service first. If you need A/C service, do yourself a favor and call Trinity A/C & Heating before making any major repair decisions. Thank you, Jimmy"

"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 ??"

"I am so glad I did not try to install our new dishwasher myself. Joseph Rand came out from All City Plumbing. We had some difficult existing conditions and our technician finished the job fast, clean and made it look easy. When I call All City back to my home for another job I will request to have Joseph come out.."

"Called in the morning, Bernie arrived in the afternoon and within 2 days we had a new AC unit located on the roof which requires a crane to install. I would highly recommend Air ASAP as you will not find anyone better nor any better price."

Small jobs welcome

"Prior to me selecting Aaceâ s heating air conditioning &swamp cooler, I interview (3) other well know AC/heating company and as most knows the â deceptionâ is real! After the initial consultations with one of the companies ( (name I wonâ t disclose)I was almost in tears about how many of their technicians were out of work and that I would help put food on their table...... I reluctantly agreed and signed the contract. After further thoughts I said to myself â he got me and immediately cancelled!! Aaceâ s heating AC & Swamp cooler they were sooo amazing and I was overjoyed with happiness! Integrity, respect, excellence, and team work they exhibited wellð ð ! I'm very picky and hard too please. I had NO option but to give frank and his team the well deserved compliments they rightfully earned!!!! Without a doubt I would recommend them to my family and friends. I forgot to mention they were very clean and took all the trash away even some of mines ð ð !!!! This review is documented from a real customer and NO one asked/ suggested I write anything. Happy customer ð ð ð !!!!"

"The blower motor on my furnace went out. Every company I asked for a quote told me I needed to replace the entire furnace and quoted me thousands of dollars to do so. I hired Cool Air For You and the tech came out the next day and replaced the blower motor in a few hours. The AC and heating works again and I didn't have to spend 4 or 5 figures. Highly recommended."

Customers say: Quick response

"Nathan is very experienced and knowledgeable. He responds quickly to every text and phone call. He and his crew show up on time, work diligently, are respectful, and focused, and do all the little details like caulking and matching paint. They installed a 5 unit mini-split system and totally completed in 2 days. The price was very good and he even passed on the incentive from the manufacturer. There are always unexpected hiccups in every construction / installation job and there was no complaining, no extra charges, he just handled them quickly and efficiently. All in all, excellent work, excellent service. We highly recommend NT Electric and HVAC."

Air Conditioning FAQs, answered by experts

AC leaks are common, and an HVAC pro can usually fix them. You may be able to resolve some leaks on your own, but a professional HVAC technician should handle most AC leak repair. If left ignored, an AC leak could cause serious damage to your system or leave you with expensive water damage, usually leading to more costly repairs or replacements.

To keep your air conditioner in good working condition, you should have it serviced by a professional at least once per year, ideally in the spring before the cooling season begins. If your AC unit is 10 years or older, consider servicing it twice a year (once in the spring and once in the fall) to catch potential problems early and help it reach its full lifespan. During a service visit, a technician will inspect, clean, and replace parts as needed. Regular maintenance helps avoid costly repairs. As a DIY task, you can also clean the evaporator coils annually.

Dirty filters are almost always the cause of poor airflow, so they should be regularly cleaned and then replaced as needed. The fan blades can also get dirty, so they should be cleaned when the unit is turned off. Make sure that the outdoor area around the back of the unit is unobstructed. Trees, shrubs, trash, and other objects could be too close to your unit.

Yes, you can clean your air conditioner filter as a temporary fix for cleaning up dirt, but you’ll eventually need to replace it once the dust starts to accumulate. Use a vacuum with a hose attachment to clean your air filter at least once per year or more often if you have pets.

You can run an HRV with air conditioning—assuming that you decide to keep the system on during the summer. The HRV will continue to bring in fresh outdoor air, which will then flow into your AC unit and cool down your home. It will also keep moving the stuffy indoor air out of your house.
