"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."

"Prompt, courteous, hard working! Called for service and they came the same day and gave me an estimate for repair and an estimate for a new furnace! I decided on a new furnace as mine was 18 years old! They came the next morning and were done within 2 hours! The thing I liked most was they didnâ t pressure me at all but waited patiently for my decision!"

"Alanis Air did a great job with my HVAC project. John Alanis answered all my questions and worked with me in deciding which system I should choose when replacing my very old system. His crew completed the work in one day, cleaned up the area and disposed of my old system. They were very efficient, knowledgeable and friendly. I would recommend Alanis Air for any of your HVAC needs! Thank you John, Santiago, Angel and Ismael :-)"

"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"..."

"Albert Nahman PHC installed new AC and Furnace for my house. I like them for several reasons -- 1. At first Tom explained in detail what equipment I need and how they work, and gave me a reasonable and detailed quote at end of the visit. 2. They offer interest free finance. 3. I got free upgrade for furnace when the original quoted is not available. 4. Their installer did good job, and cleaned up afterward. I highly recommend this company."

"I had my A/C capacitor go out on me during the peak of a heatwave. I got on all the apps to find a hvac company that could come out asap to fix it. 411 heating and AC called me back immediately after reaching out and setup an appointment for the next morning. He showed up on time, was very professional and had great tips for me on how to do some preventative maintenance on my unit to extend its lifespan. I would recommend them and use them again!"

Heating and Air Conditioning questions, answered by experts

Yes, you can potentially save $60 to $200 by handling your own air conditioner capacitor installation. However, capacitor replacement comes with the risk of electric shock. Only attempt this if you have the knowledge and protective gear to carry it out safely. Otherwise, we recommend hiring an HVAC pro with the experience to properly diagnose the issue and avoid damaging other parts of your AC unit.

The size window AC you need depends on the BTU and the size of the room you’re cooling. For a room with 8-foot ceilings, look for about 20 BTU per square foot of the room. For example, a 12-by-12-foot room should have an air conditioner with 2,880 BTU. You can buy something slightly more powerful, but don’t overshoot the BTU for a small room, or you’ll waste energy and have higher bills.

The best time of year to purchase or replace an HVAC system, including components like an air conditioner or furnace, is during the off-season—spring and fall. During these periods, HVAC professionals are less busy than in summer and winter, when extreme temperatures create urgent demand. Shopping during the off-season can lead to savings of 10% to 15% on an AC unit and allows you more time to find the best deal and other cost-saving incentives. Typically, air conditioning units go on sale in the fall after demand drops, while furnace prices tend to decrease in the spring.

Most experts recommend getting three to five HVAC quotes from licensed, insured, reputable local heating and cooling companies. Getting multiple detailed HVAC quotes (but not too many) lets you compare the equipment, services, and prices of several contractors without being overwhelmed by options. It can also let you see if one contractor’s prices are much higher or lower than the others and give you a chance to ask for clarification. That way, you can weed out any contractors who aren’t providing quality services or materials and find the company that best meets your budget, quality requirements, and long-term goals.

If left untreated, a frozen AC unit can lead to costly damage, especially to the compressor and evaporator coils. When ice forms on the evaporator coils, they become brittle and more susceptible to breaking. Plus, a freeze makes your AC system much less efficient, which means it's wasting energy and costing you more in your monthly energy bills.
