"I have used Speer Air for several years for HVAC preventive maintenance at my home. We recently expanded and they installed a package unit to take care of the expansion space. The work was good and they have been back for adjustments as necessary."

"I was in desperate need of an AC unit repair and Kyle came to the rescue. Iâ  ve owned my home since 2019 and have been looking for and honest and reliable AC technician. Iâ  ve used a couple of other technicians but Kyle will be my go to moving forward. He kept me informed of everything he was doing and educated me on how my unit should be running. He even gave me info for what filters I should be purchasing to help my unit run efficiently. He gave me several options with regards to repairs and I went with the higher priced option because it was so reasonable and I didnâ  t want to cut corners. I will be scheduling my routine maintenance with him for the summer and winter. Iâ  m so happy I finally found an AC technician I can rely on. I highly recommend him."

"I'm very happy with the work performed by this company plus the technician explained to me in detail of the work he was going to do as well as the correct way the dryer vent should have been installed before as the the exhaust vent was connected to the lower vent instead of the higher vent, saying that connecting it to the higher vent gave it more room for the lint to collect before it started clogging up the exhaust. The air duct cleaning was also conducted professionally and I have no complaint about their work. I would hire them again the next time my heating and cooling ducts needs cleaning. I'd recommend them to my friends."

"I hired Desmond for an AC and heating install. Desmond spent time explaining the different options and was really diligent about selecting the right option for us. Never pushy. He stayed late to ensure the system was working and called to check a few days later. Very professional and good value for money. I ll definitely use him again."

"

we had a leak problem and the tech came and looked over our equipment, fixed the problem and left. It cost us nothing and we have had their home heating service contracts for over 20 years.  They have NEVER ONCE not shown up or not helped and in the two furnace emergencies we had--they were here with in 1hr. 

We are very happy.

"My first and second floors were on one heating/cooling zone. The second floor was always cold. I wanted to modify the ducts in a minor way to get more air up there, but Gerson convinced me that adding a new zone with its own thermostat and separate ducts and dampers in the basement made more sense. I liked his reasoning, and, 2 days later, he and his guys showed up and did the work. They were extremely responsive, professional, and careful. The new system solved the problem. I did not take the usual steps of getting competitive bids because the reviews for MDL were so positive. Now I concur. I can't say whether the price I paid was competitive, but I paid it cheerfully."

Air Conditioning FAQs, answered by experts

Yes, it’s important to turn off your AC sometimes to give it a break and prevent it from freezing up. If your AC runs all the time, your system’s parts will wear down quicker, which may mean that you need to replace it sooner. Plus, using your AC constantly uses more electricity and leads to higher energy bills.

Yes, HVAC zoning is generally considered worth the investment by both experts and homeowners. Zoned systems offer significant benefits in convenience, efficiency, and comfort by allowing you to set different temperatures for various rooms or 'zones' in your house. This ability to heat and cool only the spaces you're using leads to energy savings and lower utility bills. Zoned systems are especially effective in multi-level homes that experience temperature fluctuations, but even smaller homes can benefit from the ability to adjust temperatures more quickly. While the up-front installation cost can be high, many find it's a worthwhile long-term investment, particularly for those who plan to stay in their home for a while.

Yes, HVAC zoning systems offer energy savings by allowing precise temperature control in different zones in your home. Rather than conditioning the whole house uniformly, these systems direct airflow where needed, preventing energy waste. Tailoring comfort to specific areas reduces energy consumption and lowers utility costs, making HVAC zoning an energy-efficient choice.

A window AC unit is not completely silent. You’ll hear the sound of air blowing, and if you put your ear right up next to the unit, you may hear a slight hiss or gurgle as the refrigerant flows through the system. That said, if your system is making a running water sound, a loud banging sound, a grinding sound, or physically vibrating, you may be facing an issue or malfunction with your AC unit.

There are several common types of HVAC systems that you may have, including split systems, hybrid HVAC, duct-free systems, packaged heating and air, geothermal heating, or even portable units for heating or cooling. If you aren’t sure which type is in your home or are looking to install something different, you should consult an HVAC pro to determine which option is right for your heating and cooling needs.
