"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."

"I needed to have the vents cleaned before I could get my dryer fixed. They came the same day. Assessed the situation and cleaned the vent within 30 mins. A pleasure to have."

"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."

"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."

"Tony was knowledgeable and explained the step by step service to be performed and why it was important to a heating system for efficiency and general maintenance. I thought the price was not inexpensive. However, I chose Ramirex Duct Cleaning due to Tony's presentation. Tony and his 2 assistants were neat, efficient and careful. My 24 year old furnace blade system and 10 vents were cleaned as well as the dryer and vent system within 3 years. Tony took before and after pictures of each phase of the operation which was impressive."

Heating and Air Conditioning questions, answered by experts

No, it isn’t necessarily bad to turn your AC on and off frequently—contrary to popular belief. Even if you stop and start your AC throughout the day, it won’t use as much energy as it would if you ran it nonstop. 

If you’re concerned about your power consumption and energy costs, there are a few simple ways to use your AC more efficiently. Regularly cleaning the filters, scheduling routine maintenance, and using a programmable thermostat are all great choices.

Yes, running your air conditioning unit too cold can cause condensation in the air ducts and built up moisture on the air filter, resulting in a breeding ground for mold and mildew. Mold and mildew growth can irritate those with respiratory issues, so it’s best to keep your AC running at a normal temperature.

If your HVAC system's capacity doesn't match the required CFM (Cubic Feet per Minute), imbalances can occur. An undersized system struggles to maintain desired temperatures, leading to discomfort. An oversized system might short-cycle, wasting energy and causing temperature fluctuations. Properly matching capacity to CFM ensures efficient and consistent heating, cooling, and home ventilation system performance.

At a minimum, an HVAC system should be serviced once per year. However, a twice-a-year service schedule—once in the spring for the cooling system and once in the fall for the heating system—is often recommended, especially for older systems, heat pumps, or in climates with extreme temperatures. Regular service, which includes inspection, cleaning, and maintenance, ensures the system runs efficiently, helps prevent costly breakdowns during peak seasons, and can extend the unit's lifespan. You can also schedule a service if you notice issues like poor performance or strange noises.

A few drips here and there should not be cause for concern, but if your unit is leaking a large amount of water, then it’s advised that you stop using it until the problem is identified and a solution is determined. The more you use it during a leak, the more issues it will cause.
