"We were recommended to Speer Air by two separate friends who have used them for years for heating and air conditioning service. Our furnace had not been serviced for two years and we wanted it looked over as we approached the heating season. Contacting the company was a snap: very organized office operation took our information and scheduled us for an appointment. Because we called as late as we did, the appointment could not be scheduled sooner than two or three weeks out. Speer Air also mailed us information about service contracts that could save us money on future calls. We did decide to go with a contract, but the initial visit was not covered as part of it.
On the day of service the technician showed up ahead of schedule. He was a delightful young man who spent an hour testing, cleaning, and insuring smooth operation of the furnace and thermostat. He explained what he did. He tolerated our wacky dog with good humor. After the job was done he presented an invoice for the work done that day. (The service contract we had paid by mail previously). No discrepancy between the telephone estimate and the invoice. 
Very satisfied with this company's thoroughness: previous furnace startups from others did not include nearly as much detail. Happy to recommend Speer Air.

"My central A/C return in the attic had a clog and Challenger, which is the best Heating and Air Conditioning Corporation in the Universe, came over a day early and so fast and fixed the clog in the A/C return right away. I love this company. My wife, Debra Jean keeps saying she's a Challenger girl for life and she means it. And the costs are so reasonable and I can't thank you enough for coming over a day early to literally save our lives. If you are in the area where Challenger works, look no further, call them. They are wonderful beyond belief."

"We found VIP HVAC using HomeAdvisor. Based on the high review feedback number we hired them to replace our furnace and the AC unit. We ran out of heat on a cold day in February. The contractor came on a very short notice. He was a subject matter expert on heating/cooling and explained all the options. He gave us a quote that was unbeatable. He also rescheduled multiple times to accommodate our schedule. On the appointed day, they came right on time even though roads were closed due to slippery conditions. Our heat furnace and AC were replaced. As a bonus he changed the fixture on the furnace unit to install a new compensating pump and a air filter enclosure that was easy to access at no cost. I will highly recommend them."

"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."

"Now I feel safe turning on the unit after the ducts and the sealing was done and cleaning my air condition and my dryer and bath room filter and my condenser outside and putting a new cover for the vent outside of my dryer. After seeing the pictures it was worth the price."

FAQs for air conditioning projects in Warren, NJ

Most professional HVAC technicians require two to three hours to complete an expansion valve replacement. The timeframe depends on your unit's accessibility and whether additional repairs are needed. The process involves recovering refrigerant, removing the old valve, installing the new component, and recharging the system. Scheduling during less busy seasons may result in more convenient appointment times.

Operating your air conditioner with a malfunctioning expansion valve isn't advisable. Continuing to run the system could potentially damage other components, particularly your compressor, which is significantly more expensive to replace. If you notice performance issues like inconsistent cooling or unusual noises, it's best to have your system inspected before continuing regular use.

Expansion valves don't have a standard replacement schedule, as their longevity depends on system usage, maintenance frequency, and environmental factors. Regular professional maintenance helps identify potential valve issues before they cause system failure. Having your HVAC system serviced annually allows technicians to monitor component condition and recommend preventative replacements when necessary.

Refrigerant leaks require prompt professional attention. If your expansion valve is leaking, you'll likely notice reduced cooling performance and possibly hear hissing sounds near the unit. Addressing leaks quickly prevents further system inefficiency and avoids the environmental impact of released refrigerant. Your HVAC technician will need to repair the leak and recharge the system with the proper refrigerant type and amount.

Because many AC issues present similar symptoms, professional diagnosis is recommended. Problems like inadequate cooling, inconsistent temperatures, or strange noises could indicate expansion valve issues, but might also stem from refrigerant leaks, electrical problems, or airflow restrictions. A qualified HVAC technician has the tools and expertise to accurately identify the root cause and recommend appropriate repairs.
