Stay cool and comfortable with premium air-conditioning systems and services from No-Frost A/C & Heating. We carry the names you trust to beat the toughest heat spell. As an added bonus, your air-conditioning unit will also remove the humidity from your indoor environment for an added degree of comfort.
Not sure if you should repair or replace? Well, consider this: if you’re operating an inefficient system that breaks down a lot, it’s likely that it’s going to break down again. That means more expensive emergency service calls or possible damage to the other components of your heating and cooling system.
Also, consider the ongoing cost factor. You could save up to 60% on your energy bills with new high-efficiency equipment. You see, even if your air conditioner is only a few years old, it could be terribly inefficient by today’s energy efficiency standards. Installing a new, high-efficiency cooling system can actually pay for itself in energy savings within a relatively short time.
Cooling efficiency for your air conditioner is indicated by its SEER (Seasonal Energy Efficiency Ratio) rating, which tells you how efficiently your unit uses electricity. In general, the higher the SEER rating, the less electricity your unit will use to cool your home. The typical SEER rating of units made before 1992 is about 6.0. In 1992, the government established the minimum cooling efficiency standard for units installed in new homes at 10.0 SEER. In 2018, the Government standard was changed to a minimum cooling efficiency of 14.0 SEER; the maximum efficiency is 25.0 SEER.

Installation of new heating and air conditioning units went very well. Technicians arrived on time and kept me informed throughout the entire process. They were very professional and completed the process in about 6 hours. They are highly recommended.
