"Of all the people I've had work on my home renovation in the last year, these guys were my favorite. Prompt, professional, honest, and reliable. When Duke came to give us the estimate, my 2 year old daughter wanted to give him a hug before he left which is unprecedented. That pretty much sealed the deal for us. They were also far and away the most reasonable quote we got. Even a friend quoted us $1500 more for less work. The installers were on time and knew their stuff. The install work is top notch as well. Everything in place and looks well put together. I highly recommend them to anyone looking for HVAC work."

"We had to upgrade our old furnace and AC so we decided to look around and call a couple companies to come and give us a quote. We decided to go with Smart heating and air, their prices were upfront and fair. We got our systems installed in a very professional manner. All the technicians wore masks, they used foot covers and put down cloths to protect our floors. After they installed they tested both ac and heater to make sure it was working. The cool thing about it is that we can control the temperature with our nest app without getting up with our phone. I love this bc I was always forgetting to turn off our system but now I can do it anywhere. I totally recommend this company. We will use them for any HVAC related concerns."

"Perfect Star sent a technician out to assess my HVAC issue. and it turned out to be my ducts had been torn apart by critters getting into my crawl space and trying to nest. I got a crawl space cleanup crew to address that problem but Martin (my HVAC technician) told me about an air purifier that could be installed to my HVAC units. He installed those for me right away and they are working great."

"Jorge, Angel, Ishmael, and George were fantastic. Jorge was honest and straight in the initial conversations. He gave me multiple options for systems and their functionality. When I made my selection I was given a very fair price for the work that was to be done. He was very helpful in acquiring good financing that bested my Credit Union and Bank. The work was done quickly with great attention to the fine details. I now have an efficient and functional HVAC unit. If you need repairs or a replacement HVAC system you could not do better than selecting Elite Heating and Air for your job. I'm telling all my friends that if they need any work done - "I've got a guy"..."

"These guys are just excellent! I made a few mistakes before I got lucky to find New Millennium HVAC. They were professional from the beginning to the end. Jose did a thorough job, cleaning the dryer vent. It was not a straightforward issue and I was afraid that we’d have to open the wall to cure the blockage. However, Jose was able to fix it. He’s an experienced professional excellent at his job, trustworthy and overall great to deal with. I’m a happy customer for years now and will rely on these guys for any HVAC related issues."

Heating and Air Conditioning questions, answered by experts

To find a reputable HVAC company, start by researching providers in your area. Look for companies with mostly positive online reviews and check the Better Business Bureau’s website for customer complaints. Next, verify their credentials. Rule out any companies that aren’t licensed, as this is a requirement in some states and municipalities, and confirm they are insured. Once you have a shortlist, contact each professional to ask key questions: How many years of experience do you have? Do you hold any third-party certifications? Do you have experience working on my specific type of HVAC system or brand? Can you provide references? What is your per-hour pricing? Do you offer maintenance contracts for ongoing savings? Do you provide a warranty for your work?

On average, an AC unit lasts between 10 and 20 years. However, the specific lifespan depends on the type of unit, how often it's used, the local climate, and the quality of maintenance. Central AC units typically last 12 to 17 years, while window units have a shorter lifespan of 8 to 10 years. Portable AC units last about 5 to 10 years, and ductless mini-split systems can last up to 20 years. To extend the life of your AC unit, it's important to perform regular maintenance, such as replacing filters, cleaning coils, and scheduling annual professional tune-ups.

Condensation forms when warmer, outside air combines with cooler air in your ductwork. This can happen when there are leaks in your air ducts, your HVAC system has a dirty air filter, or there’s a lack of insulation around the ducts. To prevent it from happening, replace your HVAC filters as directed. Also, once every five years, hire a local air duct cleaner to clean and inspect them.

Yes, but they don’t feel the same as an AC-cooled room. You’ll feel cool, moist air, opposite from an HVAC system that dries the air as it cools. Ventless units also have less tonnage than alternatives like ductless and central air, which means they aren’t as capable of quickly cooling large spaces or circulating cold air.

A frosty expansion valve that isn't blowing out cool air is a sure sign that it’s time to replace it. It might also be time to replace the TXV valve if your AC unit switches off soon after turning on or if you have poor airflow in your home.
